An efficient organic inverted solar cell with AnE-PVstat:PCBM active layer and V_2O_5/A1 anode layer

摘要

An inverted organic solar cell, which is based on anthcene-containing poly (p-phenylene-ethynylene)-alt-poly(p-phenylene-vinylene) (PPE-PPV) polymer (AnE-PVstat) and phenyl C_(61) butyric acid methyl ester (PCBM), was fabricated with Titanium dioxide (TiO_2) electron transport layer and V_2O_5/Al anode layer. In this study, we have investigated the effect of V_2O_5 thickness on solar cell efficiency. Power conversion efficiency of 3.26% has been achieved for 15 nm V_2O_5 layer. The lifetime of the cell was investigated using ISOS-L-1. The test indicated that the durability of the solar cell, which is designed in ITO/TiO_2/AnE-PVstat:PCBM/V_2O_5 (15 nm)/AI configuration, is 99% under standard solar irradiation of 100 mW/cm~2 (AM 1.5 G) at ambient conditions for 24 h.
