Questions of Simplifying the Methods of Testing Photoconverters Based on Cu(In,Ga)Se2. Part 1: A Basis for Mathematical Modeling of the Current–Voltage Characteristics
- 6 Downloads
An analysis of possible errors of laboratory studies of current–voltage (I–V) characteristics for solar cells based on Cu(In,Ga)Se2 (CIGS) using different lamps is provided, and the possibility of simplifying the procedure of testing the cells and panels by calculations and modeling is presented. Formulas are presented to develop mathematical models of the correlation between the quantum efficiency and the spectrum of the used lamp to obtain (I–V) characteristics of solar cells based on CIGS, which simplifies the testing procedure and data collection.
