Photo voltaic cells convert solar light photons into electricity. Photovoltaic solar cells fulfill two functions: photogeneration of charge carriers (electrons and holes) in a light-absorbing material, and separation of the charge carriers to a conductive contact that will transmit the electricity. Solar cells are commonly used in remote locations where cost-effective access to local power grids are not possible. The following articles contain information relating to solar photovoltaic technology and developments.

Zinc-Oxide Nanostructure Production Made Easy

Zinc-Oxide Nanostructure Two scientists are on a path-breaking method to produce 'sea-urchins' to expedite the work capacity and efficiency of photovoltaic devices. Jamil Elias and Laetitia Philippe are the two scientists from Empa's Mechanics of Materials & Nanostructures Laboratory who have been successful in producing these tiny 'sea urchins' which are ready to revolutionize solar-cell technology. New methods are generally difficult procedures, more so when the aim is to lend materials new characteristics as well by new processes. The two scientists from Thun have used materials that do not cost a bomb and they have achieved these results without utilizing any instrumentation that costs too much time and/or money.

A Power Sticker to Boost Solar Power Generation

Solar Power Sticker New and unique ways of making solar panels more efficient in power generation are coming to light every day. The new kid in the block of one such device is a large transparent sticker applied to the front of the panel which increases the power output by about 10% or so. Genie Lens Technologies is the firm which has developed these polymer film stickers. These polymer films are imprinted with special kind of microstructures. Even the panels that have been prior installed and working can have these polymer stickers applied easily to them and the stickers will boost their efficiency. View Comments

Hybrid Organic Solar Cells Now More Efficient

Hybrid Organic Solar Cells Success greets the research team of National Research Council's National Institute for Nanotechnology (NINT) and the University of Alberta. The plastic solar cells have now an operating life of 8 months instead of mere hours. And they are low-cost, environmentally efficient, unsealed plastic dollar cells - a green energy source. Developing economically viable plastic solar panels and to produce them in large scale has been the long time goal for the scientists as the cost of ultra high-purity silicon used in the traditionally manufactured solar cells is quite prohibitive. These are the solar cells of future - to be available to common man easily. A University of Alberta-NINT team has been focusing on this for quite some time. View Comments

Breakthrough in Thin-Film Solar Cells

Thin-Film Solar Cells Scientists at Johannes Gutenberg University Mainz (JGU) have come out with positive news about increased efficiency of thin-film solar cells. As we know that scientists are trying to increase the efficiency of the solar cells so that they can be considered as serious alternative to the fossil fuels. Researchers at Johannes Gutenberg University Mainz (JGU) too are working at this angle. They opted for the computer simulations to probe deeper into the indium/gallium combination to increase the efficiency of Copper indium gallium (di)selenide (CIGS) thin-film solar cells. Till now CIGS has shown only about 20% efficiency though theoretically they can attain the efficiency levels of 30%. View Comments

Economical Solar Panels to Yield More Energy

Economical Solar Panels There has been research work going on to increase the efficiency of the cost-effective amorphous solar panels. TU Delft has been the center where this research work is being developed. The research will directly help in increasing the efficiency of amorphous solar cells - from a 7% to a 9%. Crystalline silicon is most commonly used in silicon solar cells which increases the production cost quite significantly. There is a more economical type of solar panels using amorphous silicon using rather thin films of silicon. The production cost is comparatively less with these panels. View Comments

Costs for Thermo-photovoltaic Cells Significantly Reduced

Thermophotovoltaic Cell Thermo-photovoltaic (TPV) cells are great for converting radiation from any heat source to power. These cells can generate power from the wasted heat which gets released when glass or steel is produced. Adding these TPV cells to domestic power systems can help generate power along with heating water. TPV systems are also too complex for everyday use. Both of these reasons have made the TPV systems beyond industrial and domestic consumer routine set-up. View Comments
