hotovoltaic (PV) technologies are gain-ing considerable interest as one set of the most promising technologies for clean and renewable solar energy conver-sion. Thin film PV technologies are highly attractive for low-cost applications, due to small material usage and low-temperature processes, as compared with the conven-tional crystalline Si-based PVs. Additionally, lightweight, mechanically flexible thin film solar cells possess a wide range of potential applications from building-integrated PV generation to portable power sources.13 Meanwhile, it is worth pointing out that efficient light absorption is crucial for high
