Existing photovoltaic (PV) metallization techniques are far from optimal across the three incumbent technologies - crystalline silicon (x-Si), copper indium gallium (di)selenide (CIGS), and cadmium telluride (CdTe) - resulting in efficiency loss, high cost of metallization materials, and low yields. With the push for cost reductions across the entire PV value chain, optimization is needed. This report covers innovations in metallization techniques which address the key metallization issues.
