Polymer–Fullerene Solar Cells

Abstract

Abstract Polymer–fullerene solar cells are a type of organic solar cells made with conductive polymers and electron‐accepting fullerene derivatives. Among many types of organic solar cells, the polymer–fullerene combination has become the archetype due to their superior efficiency and stability. Compared to conventional solar cells, such as silicon‐based solar cells, polymer–fullerene solar cells are lightweight, potentially disposable, and flexible. Above all, the main advantage of polymer–fullerene solar cells is the fact that they are customizable at the molecular level. Here, we illustrate an insightful description of polymer–fullerene solar cells, their history of development, and methods of fabrication. Other components surrounding the polymer–fullerene active layer as well as ways to improve the performance of solar cells are also discussed. Finally, the current and future commercialization prospects of polymer–fullerene solar cells are discussed in detail.
