FEATURES OF LOADING CHARACTERISTICS OF THE CIGS PHOTOELECTRIC MODULE WHEN OPERATING ON THE SURFACE OF THE LAW

Abstract

The study o f the load current-voltage characteristics o f a solar photovoltaic module based on a polycrystalline semiconductor binary compound Cu (In, Ga) Se 2 under normal sunlight Prad = (800 ± 5) W/m2, in a temperature range o f (32 • 60) оС. It was found that with an increase in temperature, the efficiency o f the solar photovoltaic module first decreases from 10.77% to 10.65%, and then increases to 10.97%, and the coefficient o f temperature dependence o f the efficiency in these regions differs and have values KEffi ~ - 0.18 % /К, and Kejp ~ + 0.13% /К
