Abstract

 


Fig. 1	a Evolution of PSC efficiencies from 2009 to 2016 [8–14]. b Graphene is a 2D hexagonal lattice of carbon atoms (i). It can be stacked into 3D graphite (ii), rolled into 1D nanotubes (iii), and wrapped into 0D buckyballs (iv). Reprinted with permission from Ref. [41] Copyright 2012 American Chemical Society

Perovskite solar cells (PSCs) have raised research interest in scientific community because their power conversion efficiency (PCE) is comparable to that of traditional commercial solar cells (i.e., amorphous Si, GaAs, and CdTe). Apart from that, PSCs are light-weight, flexible, and have low production costs. Recently, graphene has been used as a novel material for PSC applications due to its excellent optical, electrical, and mechanical properties. The hydrophobic nature of graphene surface can provide protection against air moisture from the surrounding medium, which can improve the lifetime of devices. Herein, we review recent developments in the use of graphene for PSC applications as a conductive electrode, carrier transporting material, and stabilizer material. By exploring the application of graphene in PSCs, a new class of strategies can be developed to improve the device performance and stability before it can be commercialized in the photovoltaic market in the near future.
