Low cost high efficiency single crystal silicon solar cells for terrestrial applications have been fabricated by using inexpensive materials such as solar grade silicon wafer and pastes, and mass production processes such as screen printing and spray. Under 100 mW/cm$^2$ (AM 1.5) and $25^{\circ}C$ conditions conversion efficiency of 16.48% was obtained by anon fire-thru process and 15.55% by fire-thru process.
