초록

It is very important to optimize the reflectance of incident light in solar modules for improving output power and reducing loss of cell-to-module (CTM). It is assumed that a higher reflectance backsheet may improve optical efficiency. However how much output power is related to optical properties by reflectance property of backsheets have not been revealed clearly yet. A total of 3 types of industrial backsheets with 3 type of industrial encapsulants (EVA or POE) were analyzed as fabricated mini modules used shingled cells. According to the type of backsheets, the difference between the highest and lowest average reflectance in the range of 400 nm to 1200 nm was found to be 13.08% by UV-visible spectroscopy. Also, when using the same encapsulant, the maximum gap value of the output power increase was measured by about 3.755 mW% (166.02 mW). The correlation between reflectance and output power was experimentally found by measuring the output property of the fabricated shingled mini modules.
