A new analytical technique may lead to the formation of cheaper, more efficient solar cells. The technique uses infrared spectroscopy for studying light-sensitive organic materials.
The technique uses infrared spectroscopy to study the atom-vibrations within the material. Such study provides information about the electron movement within a film of carbon-based materials. This information, obtained, is a critical step for developing a new class of solar cells.
Developed by a team led by Penn State University researcher John B. Asbury, assistant professor of chemistry, this new analytical technique — compared to conventional silicon-based cells — will save the cost of producing solar cells significantly.
