This document specifies the minimum requirements for the qualification of concentrator photovoltaic (CPV) cells and Cell on Carrier (CoC) assemblies for incorporation into CPV receivers, modules and systems. The object of this qualification standard is to determine the optoelectronic, mechanical, thermal, and processing characteristics of CPV cells and CoCs to show that they are capable of withstanding assembly processes and CPV application environments. The qualification tests of this document are designed to demonstrate that cells or CoCs are suitable for typical assembly processes, and when properly assembled, are capable of passing IEC 62108. This document defines qualification testing for two levels of concentrator photovoltaic device assembly: a) cell, or bare cell; and b) cell on carrier (CoC). NOTE Note that a variety of alternate names are used within the industry, such as solar cell assembly, receiver, etc.<\/p>\n
