Abstract


Bulk-heterojunction (BHJ) organic solar cells (OSCs) were fabricated with various active layer materials. Solar cells of configuration ITO/PEDOT:PSS/P3HT:PC61BM/Al, ITO/PEDOT:PSS/P3HT:PC71BM/Al and ITO/PEDOT:PSS/ PCDTBT:PC71BM/Al were fabricated. Current density-voltage (J-V) characteristics were measured in the dark and under illumination in ambient conditions. A single theoretical model was able to explain the J-V characteristics of all freshly prepared cells using realistic parameters.
