Research and development into promising low-cost new materials as an alternative to silicon have been attracting increasing attention in the photovoltaic community.
Among a number of initiatives, a relatively young class of materials, namely hybrid organic-inorganic perovskites (HOIPs), has recently achieved remarkable success in photovoltaic devices. In particular, the efficiencies of perovskite solar cells (PSCs) using prototypical lead hybrid perovskites, for example, methylammonium lead iodide (MAPbI3), have soared from less than 4% in 2009 to over 24% by 2019.1
The extraordinary optoelectronic performance of perovskite materials are attributed to their high carrier mobility, long diffusion lengths. In particular, their cost-effective solution processing has opened up the prospect of applications in solar energy.2,3 Despite the intensive research efforts in this area, however, the commercialization of PSCs faces two major challenges:
