Performance improvement of c-Si solar cell by a combination of SiN_x/SiO_xpassivation and double P-diffusion gettering treatment

Abstract

SiNx/SiOx passivation and double side P-diffusion gettering treatment have been used for the fabrication of c-Si solar cells. The solar cells fabricated have high open circuit voltage and short circuit current after the double P-diffusion treatment. In addition to better surface passivation effect, SiNx/SiOx layer has lower reflectivity in long wavelength range than conventional SiNx film. As a consequence, such solar cells exhibit higher conversion efficiency and better internal quantum efficiency, compared with conventional c-Si solar cells.

Fuzzy evaluation model of software project performance based on grey clustering analysis

“…according to the designated project performance evaluation criteria, in accordance with certain procedures, through quantitative and qualitative analysis and comparison, to make an objective, fair and accurate comprehensive evaluation of the benefits and performance of the project in a certain period of operation. With the continuous development of information, the government and enterprises pay more and more attention to the return of information development [1]. Promoting the performance evaluation of project performance and the performance evaluation of enterprise information transformation has become an urgent task for information to drive industrialization in China.…”
