Ti02 Solar Cell Efficiency Rises

摘要

Paint-on solar cells are coming closer to reality every year. Recent research on the use of anatase titanium dioxide in solar cells has once again raised the photovoltaic efficiency bar -now to 15 percent -for solar cells, suggesting that it may yet become a basic block in building-integrated photo-voltaics (BIPV). While research in dye solar cells has been ongoing for decades as a less expensive alternative to silicon solar cells, a new consortium of players is aiming to make Ti02-based BIPV commercially available within a few years. Global research on Ti02-based solar cells include applications on glass, metal, flexible plastic and other surfaces. Unlike silicon-based solar cells, designed to operate in full sunlight, dye solar cells operate well in lower-light conditions.
