Method for producing photovoltaic cell

Abstract

In a method for producing a photovoltaic cell, the improvement comprising: 1) coating a portion of a semiconductor substrate with a layer of a composition comprising donor element-containing glass particles and a dispersion medium, and 2) heating the coated semiconductor substrate to a temperature sufficient to cause donor element diffusion from the glass particles into the semiconductor substrate so as to form an n-type diffusion region in the semiconductor substrate.
