The world’s current major electricity supply is produced from non-renewable energy sources and it won’t be available once it is fully used as it is depleting at a faster rate. Among the other renewable sources, solar energy is the most promising and inexhaustible source. Organic photovoltaic cells possess low manufacturing cost, flexibility, lightweight, portable and these are the major reasons for pushing the focus on organic solar cells. This report aims to discuss the potential use of an organic solar cell and tweaks made to increase its efficiency. A novel device architecture is developed and a slight modification in the active layer P3HT: PC61BM [poly(3-hexylthiophene):[6,6]-phenyl-c61-butyric acid methyl ester] weight ratio of (1:1.2) which will promote a better electron extraction and increase absorption in UV region. The GO/PEDOT: PSS is used as an hole transport layer (HTL) in the organic solar cell. Mostly organic solar cells can be easily degraded over a period of time. In this work, organic photovoltaic (OPV) cell was fabricated and checked for its stability. While reporting about its performance, the organic photovoltaic cells will play a vital role in the near future if the drawbacks are rectified.
