Fabrication and characterization of silicon solar cells

Abstract

Silicon solar cells have been fabricated in our laboratory by way of diffusing phosphorus into silicon through glassy layers, that is, the introduction of elemental phosphorus into silicon through a layer of molten phosphorosilicate glass. An electrically conducting paste applied through screen printing techniques has been used as a source for ohmic contact on the side of the cell to be exposed to sunlight, while aluminium has been used for the ohmic contact on the other side of the cell. Electrical output characteristics, transient characteristics and the spectral analysis of our cells and those Df a similar but commercially prepared have been investigated.
