Traditional photo-cells uses silicon in a crystalline state which is expensive to make, but the new technologies, such as from IowaThinFilm, claim to use amorphous silicon.

In my last podcast at theWatt.com I spoke to the CEO of ICP Solar, a company in Canada that makes thin-film PV. He was saying that there's a growing problem in the industry with companies overstating their wattage...so for example, it would say 12W on the box and actually only produce 6W. This has especially been a big problem in Kenya, which has a thriving solar market (at least in growth). There are now rules for importing soalr technology in Kenya because of these scandals, although the same problem exists in North America.

Thanks for a very comprehensive post on this topic. I am very excited about the prospects of thin-film solar technologies. I have researched these companies myself and while they are making some wild claims, I think the likelyhood of their ventures paying off is high. This technology could dramatically lower the cost of PVs and make the dream of solar panels on every rooftop an achievable possibility.

Solar has a long way to go to reach to competitive pricing that wind power has been able to offer lately. Wind has thus been getting the most attention in industrial-scale applications but these technologies could also move solar power into competitive price ranges and see a boom in large-scale solar development as well although I still prefer a distributed solution: there's so much roofspace that could be utilitzed, no sense clearing more space for PV farms, plus you get the added bonus of making the power where its used which avoids transmission losses and transmission infrastructure costs. All in all a great deal.

Nice overview of thin-film PV. I particularly welcome your pointing out that the cost of electricity is not a simple function of manufacturing cost or efficiency, as that is a point that is often missed by folks accustomed to comparing silicon with silicon. I should point out, though, that crystalline silicon is a moving target that still has plenty of room for cost improvement. While I am still a firm believer that it will someday be supplanted, any technology that hopes to dethrone it must first prove that it is manufacturable and scalable with high production yields. So far, nothing -- not even amorphous silicon, in my opinion -- has passed that test, and regardless of the success or failure of the companies you mention I fully expect silicon to continue dominating the PV market for at least another decade.

Live in New England, by the shore -
Very cold in winter, and, windy.
Summer is O.K. , but lots of wind.
Always wondered if wind power on top of roofs, couldn't be harnessed.

I am looking for a clear or nearly clear, flexible thin film PV material to put on windows. I have read a lot about this material online but I cannot find any place to buy it. Does anyone know if this material is available for sale and if so where?

Thanks.

Joe

Excellent Article.
Is there any one to Know more about organic PV.Looking for more information

A photograph (often shortened to photo) is an image created by light falling on a light-sensitive surface, usually photographic film or an electronic imager such as a CCD or a CMOS chip. Most photographs are created using a camera, which uses a lens to focus the scene's visible wavelengths of light into a reproduction of what the human eye would see. The process and practice of creating photographs is called photography. The word "photograph" was coined in 1839 by Sir John Herschel and is based on the Greek φῶς (phos), meaning "light", and γραφή (graphê), meaning "drawing, writing", together meaning "drawing with light".
