Patent
·
OSTI ID:7277981
A method of fabricating low-cost polycrystalline silicon solar cells supported on a steel substrate, which comprises: coating said steel substrate with a diffusion barrier selected from the group consisting of silica, borosilicate, phosphosilicate or mixtures thereof; and depositing successive layers of polycrystalline silicon containing appropriate dopants over said coated steel substrate such that p-n junction devices are formed which effectively convert solar energy to electrical energy.
