Scope

This document specifies the method for testing the light-induced degradation of crystalline silicon photovoltaic cells under simulated light sources. The light-induced degradation value of crystalline silicon photovoltaic cells is obtained by comparing the maximum output power of the photovoltaic cells under standard test conditions (STC) before and after the test. The test should be conducted under specified temperature and irradiance conditions.
This document is applicable to the testing of the light-induced degradation of crystalline silicon photovoltaic cells.
