Perovskite Photodetector

Perovskite solar cellsPerovskite solar cell (PSC) (PSCsPerovskite solar cell (PSC)) have attracted significant attention owing to their remarkable power conversion efficiencyPower conversion efficiency (PCE) and cost-effective production. Hybrid organic metal halideOrganic-inorganic metal halide perovskiteMetal halide perovskite (MHP) solar cellsHalide perovskite solar cells, with their heightened power conversion efficiencyPower conversion efficiency (PCE), and straightforward fabrication process, are currently a focal point in both scientific and photovoltaicPhotovoltaics circles. Perovskite materialsPerovskite materials are widely employed in optoelectronic components and offer advantages such as a high absorptionAbsorption coefficient, long carrier diffusion length, high carrier mobilityCarrier mobility, and lower defect level. These materials play a role in photoelectric devices, converting light radiation impulses into electrical signals, thereby finding applications in scientific research, as well as military and civic domains. This chapter places a strong emphasis on perovskite-based photodetectorsPhotodetectors. It delves into the physics of photodetectorsPhotodetectors, the operational principles, and the evolution of perovskitePerovskites photodetectorPhotodetectors technology.
