This lecture covers the principles and applications of photodetectors, focusing on photodiodes and photoconductors. Topics include thin-film device types, p-i-n solar cells, spectral sensitivity, and the operation of photoconductivity. The instructor discusses the fabrication and issues of CIGS and CdTe solar cells, as well as the properties required for efficient xerography. Additionally, the lecture explores organic photodiodes, perovskite-based devices, and the structure of photoreceptors for xerography. Various materials used in photodetectors, such as a-Se, a-Si:H, and organic compounds, are also presented.
