It just occurred to me that solar cells are expensive, so why do we just lay them out? By this I mean, why don't we use mirrors to concentrate light onto a smaller cell? Mirrors are cheaper, and last longer, and the smaller cell can be of optimal...
Yes, there are a number of companies such as this one http://www.technologyreview.com/business /22582/ trying to make concentrators work.
There are two basic issues to be solved with concentrators. First, you generally need to...
From towers to dishes to linear mirrors to troughs, concentrating solar power (CSP) technologies reflect and collect solar heat to generate ...
First generation solar cells began with a large amount of Silicon and only single junctions.
Second Generation solar cells called thin film cells, began with much less Silicon. In addition first generation solar was improved with...
They have recently come up with a way to turn radiation directly into electricity. Current cells must use photons only, the new ones will work with any type of radiation. Also, current radiation power sources utilize the heat to boil water to...

There is not enough concentrated sunlight in outer space to power the cells.
this answer i chose ,..i think science will have to either increase the sensitivity of solar cells or use perpetual motion power ( magnetic ) to re-power batteries in
I'm not too sure how solar cells work, but I was wondering... If we made solar cells black, would that not concentrate the light/heat and provide more energy? Or would that just block out the light from reaching the cells at all?
Solar cells don't absorb solar energy as heat.
They absorb photons into the metal, which ejects an electron. The ejected electrons forms an electric current, and voila, you have solar power.
The use of capturing heat...
I want to build a parabolic solar concentrator for the production of photovoltaic energy.
It's possible to use the normal single crystal solar cell with a concentration of 40 sun and one heat dissipation system, or I must search special...
It's possible, but you need to avoid the cell reach high temperatures, for this applications AsGa cells are much better than silicium(Si) cells, because AsGa are more efficient and are much less disturbed by high temperatures(but they need cooling...
can u explain in your own words what these mean!

Perspectives on Plastics in Solar Cells
Plastic materials are being evaluated by several leading research institutions for broadened commercial solar cell applications due to their advantages of significant cost-savings and flexibility. Concentrated photovoltaic (CPV) solar cells use materials such as glass and plastic to concentrate solar radiation onto small, high-efficiency photovoltaic cells. However, the jury is still out in many camps on whether plastics are truly reliable over typical 20 year warranty periods for solar-related products.
Several CPV manufacturers such as Amonix use plastic-based fresnel lenses for concentrating solar radiation, but many competitors like Solenergy have retained glass-based materials for optics in their systems. Many companies are designing CPV systems for enhanced reliability and longevity and are conducting more aggressive accelerated performance evaluations that extend beyond the typical 20-year forecast period; thus increasing the stringency of requirements for plastics used in CPV systems.
Amonix Concentrating Solar PV Cells achieve 39 Percent Efficiency ...
Kleiner Perkins Caufield & Byers, a venture capital firm that has up to now shown limited interest in green technology, has invested $129.4 million in Amonix , a new concentrating photovoltaic solar power company that is obtaining a 39 percent conversion rate with their III-V multi-junction cell technology. According to figures released by Kleiner Perkins, the Amonix concentrating photovoltaic method uses plastic Fresnel lenses that can “collect sunlight and concentrate it to 500 times its usual intensity onto very small, highly-efficient III-V multijunction solar cells. As a result, [these solar cells] provide the solar industry’s highest efficiencies.”
