Polymer/Organic Solar Cells: Progress and Current Status

Abstract

Organic solar cells (OSCs) have sparked widespread interest in recent decades due to benefits such as low cost, flexibility, semitransparency, non-toxicity, and suitability for roll-to-roll large-scale production. The development of OSCs with high-performance active layer materials, electrodes, and interlayers as well as innovative device architectures has made significant strides. In particular, the advancement of OSCs' power conversion efficiency (PCE) has been greatly aided by the development of active layer materials, including novel acceptors and donors. Photovoltaic cells are one of the most promising renewable energy sources for resolving energy and environmental challenges. Organic solar cells (OSCs) have several advantages over other photovoltaic technologies, including low cost, lightweight, semi-transparency, and flexibility. This final benefit, which results from the inherent flexibility of organic active layers, is unique to OSCs. Flexible OSCs (F-OSCs), which have intriguing applications in areas like wearable electronics and building-integrated photovoltaic, have progressed quickly in recent years, and great progress has been made in this area. In this chapter, we provide an overview of current developments in semi-transparent organic solar cells, polymer-based solar cells and their Fullerene-containing polymers for organic solar cell. Additionally, a brief discussion of fullerene-containing polymers for organic solar cell was specified. The final step is the presentation of difficulties for the advancement of F-OSCs.
