Physics and design of bifacial perovskite photovoltaic devices

Bifacial photovoltaic devices harvest solar irradiance from their front and rear surfaces, boosting electrical power production per footprint area. Metal halide perovskite solar cells possess the potential to realize efficient bifacial thin-film photovoltaics owing to their outstanding optoelectronic properties and unique features of device physics. This talk will discuss device physics, design principles, fabrication, and measurement of highly efficient bifacial perovskite solar cells. Our technoeconomic analysis shows that bifacial perovskite solar cells can outperform their monofacial counterparts with higher energy yields and lower levelized costs of energy (LCOE) in future commercialization.
