The Pastes with Prototype Additive Deposited on Front Side Metallization Used in Photovoltaic Solar Cells

Abstract

In this paper are presented both the fill factor of 0.75 and an efficiency approaching 14.64 % of solar cell, which were achieved, despite the non-optimized process. A new Cu-based additive of pastes were applied for formation of front contact on silicon solar cells. Front contact were screen-printed using commercial silver paste containing the CuXX additive prepared at laboratory. It is the world's first copper based paste appropriate for high-temperature production processes of front contact of the solar cell.
