Abstract
A method of photoplating a metal contact onto a surface of a cathode of a photovoltaic device is provided using light induced plating technique. The method comprises: a) immersing the photovoltaic device in a solution of metal ions, where the metal ions are a species which is to be plated onto the surface of the cathode of the photovoltaic device; and b) illuminating the photovoltaic device, using a light source of time varying intensity. This results in nett plating which is faster in a direction normal to the surface of the cathode than in a direction in a plane of the surface of the cathode.
