Abstract
We investigate the artificial aging of PV modules interconnected with the aluminum-based mechanical and electrical laser interconnection (AMELI) process. AMELI forms a laser welded connection between the Al-metallization on the rear side of the solar cell and an Al-layer on an interconnector substrate. AMELI avoids soldering, conductive adhesives, and Ag-pastes. We investigate glass and encapsulant films as possible interconnector substrates that carry an Al-film. Modules processed with high temperature-deposited aluminum on the cells and an encapsulant as interconnector substrate do not degrade during 200 humidity-freeze cycles. The conversion efficiency η, the fill factor FF, the open circuit voltage Voc, and the short circuit current I sc are unaffected by the artificial aging within an accuracy of 1%.
