Solution Introduction
The laboratory testing solution for crystalline silicon solar cells takes "precise characterization + data empowerment" as its core, focusing on the research and development needs of high-efficiency cells and process optimization, and builds a full-process testing system covering material entry, structure preparation, performance evaluation to reliability verification. The solution integrates core technologies such as minority carrier lifetime testing by microwave photoconductivity attenuation method, elliptically polarized film layer characterization, and SEM microstructure observation, precisely controlling key material and structural parameters such as silicon wafer purity, doping concentration, and film layer thickness. By using an AAA-level solar simulator in combination with an IV test system and a quantum efficiency tester, high-precision quantitative analysis of core photoelectric performance such as conversion efficiency and spectral response is achieved. At the same time, infrared thermal imaging technology is utilized to locate potential defects such as hidden cracks and false soldering. In response to the requirements of reliability verification, the solution is equipped with high and low temperature and humidity test chambers, ultraviolet aging test chambers and other devices to simulate the stability performance of batteries under extreme environments, providing data support for long-term service performance evaluation. The entire solution strictly adheres to industry testing
