- •
Two small molecular donor materials ICT1 and ICT2 have been developed for BHJSCs.
- •
Thermal, optoelectronic and photovoltaic properties of ICT1 and ICT2 are explored.
- •
BHJSCs with PC71BM acceptor showed PCE of 5.12% and 5.90% for ICT1 and ICT2.
- •
Impact of side chain and TSA of active layer is investigated using XRD and AFM.
- •
Moreover, this is the first report on BDT-DTP based donor materials for SMBHJSCs.
