New Types of Solar Technology

It is an exciting time in the solar industry right now, with various breakthroughs and important discoveries made lately to further the quest for better and better solar cells. Scientist from around the world, including top notch Australian researchers, have developed ingenious ways of making solar energy more viable and cost effective.

Thin Film Solar Cells

Scientists have discovered that thinner solar cells are capable of trapping more sunlight than traditional arrays of solar cells. By making them thinner and intentionally roughing the surface of the cells, the light bounces inside the cell which results in better absorption and efficiency.

Thinner solar cells are also cheaper to manufacture, and by improving the absorption of electrons also further boost efficiency and output. University of New South Wales professor Martin Green recently revealed that this breakthrough will also serve as a backbone to organic semi-conductors and even plastic solar cells.

Though plastic is not an ideal material for solar panel arrays, Professor Green said that the thickness that the researchers are dealing with will allow plastic to work because of the low optical density that the thin solar cell processing will require.

Nano-sized solar cells

Recently this year Australian researchers invented a nano-sized solar cell about 1/100th the size of an average solar cell found in regular solar panels. These solar cells, or quantum dots, are made from cadmium telluride, which has good light absorbing characteristics.

The quantum dots are so small that they can be suspended in a liquid medium.

This will allow solar manufacturers to directly mass produce roofing materials that have built in solar cells, and they will be a cheaper price because of its less complex process.

The reduced size of the quantum dots hasn’t greatly compromised their efficiency rate; researchers said that the solar cells have an efficiency rate of 12% against the current 18% of traditional solar panels. This new technology will not be limited by your available roof spaces though, so you can generate more energy per home.

Stacked printable Solar cells

Lead researcher Dr.Udo Bach from the Monash University in Melbourne, in collaboration with the University of Ulm in Germany, discovered that stacked printable solar cells are capable of producing more energy than a single active electrode solar cell.

Dr. Bach explained that printable solar cells already have 2 electrodes stacked on each other,however one of them is inactive. The breakthrough is thatDr. Bach and his team found a way to replace that inactive electrode with an active one making it more efficient.

Although this technology is still under extensive research and development because of the relatively low efficiency rate compared to today’s solar panels, researchers believe that due to the fact that it can be printed onto cheap polymers, this technology will someday revolutionise the solar industry.

3-D solar panels

Dr Zhong Wang of the Georgia Institute of Technology, together with US scientists, is now developing the so called “3-D” solar panels which use fibre optic technology instead of the typical solar cells.

The fibre optics work by collecting sunlight into the protruding tip, and as the light travels down the length of the cable the zinc oxide converts it to electricity. The two stage conversion process allows the zinc oxide to convert any missed light during the first stage.

Currently the technology has an efficiency rate of 3.3%, which as an example means that a 10 watt light bulb will be powered per 4 inches of fibre optics.

While mostly still in the development phase these innovations in solar power promise an exciting and better future for us, with sustainable and clean energy becoming cheaper and more effective, and the bonus of greatly reducing carbon emissions around the world.

Solar Cells

A solar cell is a device that converts the energy of sunlight directly into electricity by the photovoltaic effect. Sometimes the term solar cell is reserved for devices intended specifically to capture energy from sunlight such as solar panels and solar cells, while the term photovoltaic cell is used when the light source is unspecified.

The term “photo” derives from the Greek word for “light,” and the term “voltaic” comes from the word “volt” which means “electrical force.” A “cell” is a small receptacle or container containing electrodes which generate power.

Thus, a photovoltaic cell is a container that creates electric force, through light.

Whereas a solar cell can generate electricity from any light source, its intended use is the collection of solar energy from the sun.

How a Solar Cell Works

The solar cell works as follows:

Photons (which are particles of light in sun rays) hit the surface of the solar cell and are absorbed a semiconductor, such as silicon.

These photons (bits of sunlight) knock electrons loose from the atoms inside the semiconductor. The photons then push the electrons along, leaving a “gap” in the atom. Another electron is then pulled from an adjacent atom to fill the gap. And so an electrical flow is generated.

The simplicity of this is that one atom has an extra electron, and the other atom is missing one. This is referred to as a “difference in potential.” Nature, wanting to remain balanced, tries to even things out by pulling another electron from the neighboring atom.

A solar panel is comprised of a group of solar cells which are linked together to produce the desired amount of electrical energy.

A group of solar cells linked together can also be referred to as a “module.” Thus the terms “solar panel,” and “solar module,” are synonymous to each other, and essentially mean the exact same thing.

“Solar panel” is the more common term, and “solar module” is the technical term.

One can use solar panels individually or one can link several together in order to generate more electricity. When a group of solar panels are linked together, it is called a “solar array”. The more solar panels are included in a solar array, the more power they produce.

Solar Power is a clean and virtually unlimited source of energy. I say “virtually unlimited” because the sun itself won’t last forever. But we won’t have to worry about that for the next few billion years.

Since solar power is a clean energy source which has been around for decades, one might wonder why its not used more. The answer to this lies partially in the cost of producing solar panels, as well as in the efficiency of the solar panels.

We are currently in the second generation of solar panel technology and verging on the third. A lot has changed since the first generation. Solar panels a are becoming a viable source of clean energy.

The solar cells of earlier times were relatively large and bulky compared to our current models. In view of the amount of energy and material required to produce them, and the amount of energy they actually produced, it was more costly to use solar energy than to use fossil fuels. The only exception was in places where little or no fossil fuels were available, such as in space.

With the second-generation solar cells, we attempted to tackle this exact problem. We attempted improve manufacturing techniques so as to reduce the costs, materials and energy needed for the production of solar cells.

Recently, major advances have been made in the production of solar cells, which have reduced production costs.

One contribution in this area was the development of techniques to coat glass or ceramic materials with very thin layers of semi-conductive substances. This made it possible to produce solar panels using only a fraction of the semi-conductive material that was required earlier. The production of solar panels using this second-generation technology is referred to as “Thin Film Technology.”

Third-generation solar energy technologies are currently being researched and developed. The objective is to improve the power of solar cells even further (while keeping production costs to a minimum) in which case thirty to sixty percent of the sunlight hitting the panels will be converted into electricity. (Currently, solar panels convert only about twenty percent.)

But regardless of third generation solar technology, the second-generation solar cell is efficient enough to make solar technology viable – and a host of new solar-powered products have hit the consumer market.

Solar-powered calculators have been in use for a while now, we’ve all seen them. We have even seen a few other novelty devices. But only in the last few years have solar devices come into serious and practical use.

The last two years in particular have seen a virtual explosion of solar devices hitting the market. Solar flashlights (I’ve often wandered what use they were), solar-powered radios, and, recently, solar battery chargers.

One can also now find a wide range of portable solar chargers and panels, which are lightweight and easy to transport, yet capable of providing a decent amount of power in even the most remote locations. Solar chargers are becoming a standard part of wilderness survival kits and emergency preparedness kits.

All of this is a result of the developments in solar cell technology, and the coming of the Solar Age.

Solar Power – Pool Solar Heaters

Solar power products that are used at home include solar heaters which focus thermal energy from the sun.  This principle can be used to heat water to replace the cold water in the pool. The pool solar heater system is a solar powered hot water system to use in pools. Unlike other types of solar powered devices, pool solar heaters are rather simple and can extend the swimming season considerably.

Solar power products have been in the market for a long time, ranging from home solar power products to solar products for large scale consumption like street lighting. Solar power products for lighting are fixed with batteries, chargers, solar panels and converters which all work together to produce electricity. 

Solar powered hot water heaters are now replacing electric heaters that burn fossil fuels, and in the process release harmful carbon and other greenhouse gas emissions that contribute to global warming. You could help the environment by using solar powered hot water heating systems. 

Solar heating systems are generally composed of solar thermal collectors, a fluid system to move the heat from the collector to its point of usage. When a solar water heating and hot-water central heating system are used in conjunction, solar heat will either be concentrated in a preheating tank that feeds into the tank heated by the central heating, or the solar heat exchanger will be lower in the tank than the hotter one. When the initial costs of a solar system are properly financed and compared with energy costs, then in many cases the total monthly cost of solar heat can be less than other more conventional types of hot water heaters (and also in conjunction with an existing hot water heater).

There are lots of companies out there that can provide you with everything you will need to convert your heating system to run on solar power. You can buy solar powered water heaters in many different sizes and shapes; this makes them suitable for different applications. A solar powered water heater should pay for itself over time as you don’t need to pay for hot water again.

There are some do-it-yourself plans for creating your own pool solar heater, but that obviously will take some time and a certain amount of expertise.

It is really not that difficult and well within the reach of a person with average skills. I, however, would go for an already built system.
