Optical Modeling of Organic Solar Cells Using the COMSOL

Jungho Kim[1]
[1]Department of Information Display, Kyung Hee University, Seoul, South Korea

A solar cell offers a potential solution to energy shortage problems by converting sunlight into electrical power. Organic solar cells (OSCs) are low-cost and versatile, but also tend to be low-efficiency and short-lasted. Three macroscopic parameters determine their power-conversion ... En savoir plus
