Progress on Organic Solar Cells: A Short Review

Abstract

Thin film organic solar cells have emerged as a replacement to inorganic solar cells based on silicon. Organic solar cells offer several advantages compared to silicon-based devices. In the last 10 years, concentrated research attempts towards accomplishing the mandatory power conversion efficiency of 10 % and environmental stability of the device still remain a main challenge. In order to influence the efficiency, polymers are frequently utilized to fabricate the absorber and buffer layers. Also, binary and tenary polymer blends have been devised to influence the performance in micro/nanostructures. In addition, the advantages of organic solar cells for realistic application, and potential solutions are also considered.
