Abstract

Recent advances in wide-bandgap (WBG) perovskite solar cells (PSCs) demonstrate a burgeoning potential to significantly enhance photovoltaic efficiencies beyond the Shockley–Queisser limit for single-junction cells. This review explores the multifaceted improvements in WBG PSCs, focusing on novel compositions, halide substitution strategies, and innovative device architectures. The substitution of iodine with bromine and organic ions such as FA and MA with Cs in the perovskite lattice is emphasized for its effectiveness in achieving higher open-circuit voltages and reduced thermalization losses. Furthermore, the integration of advanced charge transport layers and interface engineering techniques is discussed as critical to minimizing open-circuit voltage (V_OC) deficits and improving the photo-stability of these cells. The utilization of WBG PSCs in diverse applications such as semitransparent devices, indoor photovoltaics, and multijunction tandem devices is also explored, addressing both their current limitations and potential solutions. The review culminates in a comprehensive assessment of the current challenges impeding the industrial scale-up of WBG PSC technology and offers a perspective on future research directions aimed at realizing highly efficient and stable WBG PSCs for commercial photovoltaic applications.
