Future energetics will be strongly dependent on solar cell technologies. Currently, the market is dominated by silicon-based technologies, which are becoming more and more affordable to customers. Historically, the main driving force for cost reduction was an increase in the efficiency of solar panels. However, Si solar cells are approaching the theoretical limit, and therefore conceptually new devices must enter the market as soon as possible. One of the ways to overcome limitations is to construct so-called tandem solar cells. In such devices, two (or more) absorber materials are combined into one device, thus reducing the thermalization losses. Recently, perovskite semiconductor materials have emerged as promising materials for solar cell applications. In particular, they are attractive for use in tandem devices, due to the possibility to adjust their bandgaps. However, for perovskites with different bandgaps, the other components of the solar cell also need to be adjusted. In this scope, self-assembled hole-selective monolayers can serve as a platform to reduce interfacial losses and improve the overall performance of devices by means of molecular design.
