CIGS Electroluminescence Offers Insights Into Cell Structure, Quality

 

Abstract

Copper indium gallium (di)selenide (CIGS) thin-film cells for solar energy generation offer decisive economical advantages by enabling the manufacture of lightweight and flexible modules. The development of thin-film solar cell can be accelerated by performing electroluminescence analysis.

Analyzing CIGS cells’ inherent near-infrared electroluminescent radiation with sensitive indium gallium arsenide shortwave infrared (InGaAs SWIR) cameras allows for detailed structural examination that can shorten the development cycle of new module types and support module manufacturing through components and facilities that meet high reliability, high efficiency and long-term operability.
