SR-156 Solar Cell Spectral Response Measurement System

Product Name : Solar Cell Full-Area Spectral Response Measurement System

Item No. : SR-156

Description

SR-156 is a solar cell spectral response measurement system designed by Enli Technology Co., Ltd., and also is the first modular full-area (156×156 mm2 ) illumination equipment in the world, can measure the spectral response of the whole cell. The full-area result resembles the overall cell response better and can be utilized to calculate the Spectral Mismatch Factor according to IEC standard. This resolves the situations when localized-area measurement or mapping results might misrepresent the whole cell. It is now implemented by target research centers and major cell manufacturers to improve the conversion efficiency of solar cells.
