According to the characteristics of different light absorption curves of different types of solar photovoltaic cells, the corresponding anti-reflection films were designed respectively. The transmittance of films under different models was simulated by TFcal software. The films and key parameters suitable for different types of cells were obtained. The optical transmittance of films was tested by ultraviolet-visible-infrared spectrophotometer. The electrical properties of c-Si solar cells covered with anti-reflection film were tested by xenon lamp solar simulator and digital source meter. The results show that the optimal anti-reflection films of different solar cells is different. The highest average transmittance of the prepared film in 380~1 200 nm is 93.1%. When the film with an average transmittance of 92.5% is used, the battery obtains a relatively better battery efficiency, and the output power is 1.129 771 mW.
