In recent times, perovskite solar cells (PSCs) have been of wide interest in solar energy research, which has ushered in a new era for photovoltaic power sources through the incredible enhancement in their power conversion efficiency (PCE).
Five new poly(selenophene–thiophene) were synthesized for polymer optoelectronic applications. The hole field effect mobility and polymer photovoltaic power conversion efficiency could be as high as 0.27 cm2 V−1 s−1 and 2.3 %, respectively.
