Stabilization procedures for TOPCon PV modules after UV-induced degradation

Solar Energy Materials and Solar Cells
The study investigates the stabilization behavior of Tunnel Oxide Passivated Contact (TOPCon) photovoltaic (PV) cell technology following UV-induced degradation (UVID). It focuses on the after-effects of lab-induced UVID, particularly the drastic effects of power loss during dark storage after UV irradiation.
