Abstract: Cadmium Telluride thin film solar cell is very suitable for building integrated photovoltaics due to its high efficiency and excellent stability. To further reduce the production costs, relieve the scarcity of Tellurium, and apply in building integrated photovoltaics, ultra-thin CdTe photovoltaic technology has been developed. Some study have discussed the research progress of ultra-thin solar cells in terms of silicon and copper indium gallium selenide solar cells, but there are few review papers from the aspect of CdTe solar cells. This review focuses on the ultra-thin CdTe solar cell for the first time and provides a comprehensive and systematic summary. Firstly, the structure of this device is described, and the history of its development is reviewed. Secondly, the advantages and disadvantages of different methods are discussed, and the corresponding solutions are given. Thirdly, the factors limiting device efficiency are analyzed and future directions are suggested. Lastly, the application of ultra-thin device in semi-transparent devices is presented and the challenges are summarized. By reviewing a wide range of materials, we aim to provide valuable insights into the development of ultra-thin cadmium telluride solar cells and to promote its application in building integrated photovoltaics, which is of great importance in reducing carbon emissions to achieve sustainable development.
