Title:
COMPOSITION FOR FORMING IMPURITY DIFFUSION LAYER, PROCESS FOR PRODUCING IMPURITY DIFFUSION LAYER, AND PROCESS FOR PRODUCING SOLAR CELL ELEMENT
Document Type and Number:
WIPO Patent Application WO/2012/005253
Kind Code:
A1
Abstract:
Disclosed is a composition for forming an impurity diffusion layer, the composition comprising a glass powder containing a donor element or acceptor element, a binder having a weight-average molecular weight of 5,000-500,000, and a solvent. When the composition is for forming an n-type diffusion layer, the glass powder contains a donor element. When the composition is for forming a p-type diffusion layer, the glass powder contains an acceptor element. By applying the composition for impurity diffusion layer formation and subjecting the applied composition to a thermal diffusion treatment, an n-type diffusion layer or a p-type diffusion layer is produced. A solar cell element having the n-type diffusion layer or p-type diffusion layer is produced.
