degradation

Researchers at the University of New South Wales (UNSW) have developed the world's first comprehensive map of ultraviolet (UV) radiation for solar modules.

Researchers from the University of New South Wales (UNSW), Australia, have directly observed how silicon solar cells can self-repair UV damage under sunlight.

The use of POE as an encapsulant in TOPCon module construction could limit the effects of degradation on the module’s electricity generation.

The inclusion of a thicker aluminium oxide layer in TOPCon solar cells could provide superior resistance to UVID, according to UNSW.

TOPCon solar modules show signs of accelerated degradation, which undermines the long warranties promised by many manufacturers, according to new findings from German researchers.

Researchers have called for enhanced international standards to detect ultraviolet-induced degradation (UVID) in PV modules after identifying “severe” levels of the problem in operational n-type panels.             

Wenzhong Shen, Sheng Ma and Huanpei Huang present an overview of the ultraviolet-induced degradation affecting TOPCon cells and modules.

Researchers in Japan have undertaken a comprehensive study to test the degradation of perovskite solar cells in extreme heat and humidity.

Fraunhofer ISE’s study uncovered critical degradation effects caused by moisture ingress and UV irradiation in accelerated aging.

Modules will need to pass the 2021 version of the IEC 61215 testing series if they are to be approved by the CEC.
