Abstract:
1. A method of manufacturing solar cells, the method comprising: depositing, in a liquid phase, an etch-resistant dopant material on a silicon substrate, the etch-resistant dopant material comprising a dopant source and a solvent; forming a cross-linked matrix in the etch-resistant dopant material using a non-thermal cure of the etch-resistant dopant material, the cross-linked matrix having a structure, and the non-thermal cure causing a phase change of the etch-resistant dopant material from liquid to solid; subsequently, removing the solvent from the etch-resistant dopant material without altering the structure of the cross-linked matrix; and heating the silicon substrate and the etch-resistant dopant material having the cross-linked matrix to a temperature sufficient to cause the dopant source to diffuse into the silicon substrate.
