Abstract Photon-enhanced thermionic emission (PETE) solar cell is an emerging of solar cells, and it is a combination of photoelectric and thermionic emission effects, which has high photoelectric conversion efficiency in theory, in which vacuum near-contact structure of PETE solar cells under the condition of 1 000 times more concentrated, the theory of the photoelectric conversion efficiency will be higher than 40%, and the combination of waste heat utilization system can make the total conversion efficiency up to 50%, far above the same concentrated light condition of normal photovoltaic solar cells. Therefore, it has received extensive attention. The paper briefly introduces the structure and working principle of PETE solar cell, summarizes the three main research directions: light absorption, electron emission & surface recombination and space charge effect as well as research progress of PETE solar cell at present, and PETE solar cells for the future development prospect are also discussed, in order to provide references for the development of PETE solar cells.
