Abstract
Plastic solar cells, primarily based on conjugated polymers and fullerene derivatives, have garnered increasing attention due to their potential for low-cost, flexible photovoltaic applications. This paper reviews the recent advancements in device architectures, photophysics, and stability of plastic solar cells, focusing on improved efficiency and scalability for large-area applications. The study emphasizes the significance of donor-acceptor (D/A) heterojunctions and bulk heterojunctions in enhancing power conversion efficiencies. In addition, this paper outlines the challenges related to stability and suggests potential routes for further enhancement. Experimental data are presented, highlighting current-voltage (I-V) characteristics, external quantum efficiency (EQE), and long-term degradation studies.
