Abstract Selective emitter (SE) has bcome one of the focus of the PV industry for its high photoelectric conversion efficiency. Using Matlab software, this paper simulated the relation between finger spacing and width to get the minimum energy loss. Under the guidance of the theoretical calculation, we selective emitter solar cells were fabricated whose emitter is fulfilled by printing process. Based on the measuremnt and the analysis of ECV, IV, QE etc., it is found that the SE solar cells are superior to normal solar cells, and the conversion efficiency of the SE solar cell is enhanced by about 1%.
