Abstract:
A method for use in forming a photovoltaic device includes forming a doped semiconductor layer on a surface of a semiconductor substrate and forming a metal film on the doped semiconductor layer. A patterned etched resist is formed on the metal film and a dielectric layer is formed on the doped semiconductor layer and the etched resist. A laser having a wavelength absorbable by the patterned etch resist is applied through the dielectric layer to the patterned etch resist to remove the patterned etch resist.
