Many people envision solar power as rigid silicon panels mounted on a roof. With thin film solar cells, you’re more likely to not see them, or even know they’re there. This article is about a real-life thin film solar project.
Not many bloggers are able to witness the technologies we research and write about. It’s one thing to be able to buy afford a cool “green” gadget (usually not very green), but another to see the many forms of solar, wind, geothermal, etc., which are always changing and developing around the world. So when my employer decided to go solar, you might imagine my excitement.
At the moment I work for Magco Inc., a Tecta America company. Tecta is a national commercial roofing corporation that can install green roofs, solar lighting, and solar panels alongside a variety of traditional roofing systems. This solar project is pretty straight forward: our building has a big, flat roof on top of a hill without any shade. You’d have trouble finding a sunnier spot for solar panels.
I was double delighted when I heard that they ordered thin-film solar! Naturally inquiring minds wanted to know: why and what kind?

A May 16 article in the New York Times focused on the debate in Germany regarding whether generous subsidies for solar energy should be continued. Buried in the story was the remarkable fact that Germany has created 40,000 jobs in formerly blighted industrial areas by “turbo-charging” the growth of the solar industry there. Imagine if our government took a leadership role in jump-starting solar production in areas like [...]

New trends spotted at the American Solar Energy Society conference last week in San Diego (courtesy of Illinois Solar Energy Association President Mark Burger, who attended):
- From Bosch, a new generation of solar flat plate collectors (used in solar thermal water heating applications) that can be mounted on the roof at a lower angle, addressing some peoples’ aesthetic concerns. The panels are also lighter-weight and easier to mount even on high roofs. Low-profile collectors were also

From time to time the National Renewal Energy Lab (NREL) reminds us that the US used to be a leader in innovation. This time it’s in the area of solar thin film technology. The goal with solar thin film technology is to surpass the efficiency level of silicon solar cells. Efficiency refers to the rate at which sunlight falling on a solar cell is converted to electricity. Silicon has been the most efficient material, but it is is expensive and limited, so the world is seeking alternatives. (Picture above from the Dept. of Energy shows thin film manufactured by Iowa Thin Film Technologies.)
NREL has set a new world record using CIGS (copper indium gallium diselenide) thin film, which in tests has reached 19.9 percent efficiency, coming very close to the 20.3 percent level of multicrystalline solar cells.
Who says President George Bush isn't green? Alright, well, most of you — but in a day and age when it's hip to be environmentally-friendly for all the right (and wrong) reasons, the current administration is making green headlines on a more consistent basis. From the Associated Press comes news this morning that Energy Secretary Samuel Bodman is set to announce funding from Bush's Solar America Initiative for growing technology company,
