- Abstract
Minimizing the photon losses by depositing an anti-reflection layer can increase the conversion efficiency of the solar cells. In this paper, the impact of anti-reflection coating (A R C) for enhancing the efficiency of silicon solar cells is presented. Initially, the refractive indices and reflectance of various A R C materials were computed numerically using the O P A L 2 calculator. After which, the reflectance of SiO 2 , TiO 2 , SiN x with different refractive indices (n) were used for analyzing the performance of a silicon solar cells coated with these materials using P C 1 D simulator. SiN x and TiO 2 as single-layer anti-reflection coating (S L A R C) yielded a short circuit current density ( J s c ) of 38.4 mA / cm 2 and 38.09 mA / cm 2 respectively. Highest efficiency of 20.7 % was obtained for the SiN x ARC layer with n = 2.15 . With Double-layer anti-reflection coating (D L A R C) , the J s c improved by ∼0.5 mA / cm 2 for SiO 2 / SiN x layer and hence the efficiency by 0.3 % . Blue loss reduces significantly for the D L A R C compared with S L A R C and hence increase in J s c by 1 mA / cm 2 is observed. The J s c values obtained is in good agreement with the reflectance values of the A R C layers. The solar cell with D L A R C obtained from the study showed that improved conversion efficiency of 21.1 % is obtained. Finally, it is essential to understand that the key parameters identified in this simulation study concerning the D L A R C fabrication will make experimental validation faster and cheaper.
