3 terms, definitions and symbols
3.1 Terms and definitions
The following terms and definitions apply to this document.
3.1.1
Initial light attenuation initiallight-induceddegradation
The battery used in the initial, after a certain period of time after the light, the internal defects caused by a small number of carriers to reduce the life, causing the battery
The maximum output power is reduced.
3.2 symbols
The following symbols apply to this document.
PI --- the maximum output power of the battery under initial test conditions without initial optical attenuation;
PF --- the maximum output power of the battery after the initial photo-attenuation, the maximum output power in the standard test conditions stabilized.
4 Principle of the method
Under certain conditions, the use of a certain amount of exposure to the indoor simulation of light irradiation of the battery, so that the initial light attenuation. By comparing the photochromic
The maximum output power of the battery under standard test conditions is calculated before subtracting and attenuating the battery, and the initial attenuation rate of the battery is calculated. Standard test strips
The maximum output power of the battery at 1000W/m2, 25 ° C, AM 1.5 is measured according to IEC 60904-1.
