Revealing the Working Principle of Cadmium Telluride Photovoltaic Glass, Green Energy Technology Gains Attention
2025-07-11
Recently, cadmium telluride power-generating glass has been widely used in green energy and building photovoltaic integration projects due to its unique properties, and its working principle has attracted extensive attention. Cadmium telluride power-generating glass typically uses a "sandwich" structure, adding a layer of cadmium telluride film only a few micrometers thick between two pieces of glass to achieve power generation. Professor Zhu Lei from the School of Civil and Transportation Engineering at Beijing University of Civil Engineering and Architecture explained that the thin-film battery is the core of cadmium telluride power-generating glass, and its basic function is to convert solar energy into electrical energy. When sunlight shines on the surface of the film, the incident photons excite electrons in the film, causing them to move and thus generate an electric current.

According to technical experts, the cadmium telluride thin film is densely packed with millions of PN junctions, acting like miniature "energy switches." The energy carried by photons matches the bandgap of cadmium telluride, allowing electrons in the valence band to jump to the conduction band like a key unlocking a lock, generating mobile photogenerated carriers. These carriers are collected and transmitted through a transparent conductive oxide layer, achieving the conversion from light energy to electrical energy.
At the same time, studies have shown that cadmium telluride material exhibits excellent spectral absorption. Besides visible light, it can also absorb parts of infrared and ultraviolet light. Therefore, even under weak light conditions such as dawn, dusk, or cloudy weather, cadmium telluride power-generating glass can still maintain a certain level of power generation, effectively broadening its applicable scenarios.
Currently, many enterprises in various regions are enhancing the performance of cadmium telluride power-generating glass through various innovative technologies. For example, Jiamusi Zhongjian Material Photovoltaic Materials Co., Ltd. uses near-space sublimation and other technologies, not only overcoming the difficulties in preparing cadmium telluride thin films but also significantly improving the photoelectric conversion efficiency of large-area products. Their products have been applied in many projects, such as the rooftop of the Panzhihua Graphite Industrial Park, achieving good benefits. With continuous technological breakthroughs and cost control, cadmium telluride power-generating glass is expected to be widely applied in more scenarios, contributing to the global green energy transition.
