An overview of photovoltaic performance of organic solar cells using PCDTBT:PCBM and PTB7:PCBM active-layer materials

In recent years organic material based SCs (solar cells) has gained huge attention over traditional photovoltaics due to its low manufacturing cost, renewable feedstock, production scalability, light weight and mechanical flexibility. However the efficiency and durability of organic material based SCs need to be enhanced to make it commercially successful. Active layer material used in organic SC plays a significant role in determining its durability. P3HT:PCBM is the widely used active layer material. Various studies were carried out with different combination of active layer materials to enhance the performance of organic SCs. In this article we have studied the performance of organic SCs fabricated using two different active layer materials namely PCDTBT:PCBM and PTB7: PCBM
