BS EN IEC 62787:2021 pdf free.Concentrator photovoltaic (CPV) solar cells and cell on carrier [CoC) assemblies—Qualification.
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 (C0C).
NOTE Note that a variety 01 alternate names are used within the industry, such as solar cell assembly, receiver, etc

3.1 bare cell refers to a semiconductor die level. The physical form during a commercial transaction may be a separated solar cell, a diced wafer on tape, or even a processed wafer. The one common denominator is that the qualified configuration is completely unprotected and not ready for interconnection with the rest of a CPV module.BS EN IEC 62787 pdf free download.
