Abstract
A silicon solar cell having a silicon substrate includes p-type and n-type emitters on a surface of the substrate, the emitters being doped nano-particles of silicon. To reduce high interface recombination at the substrate surface, the nano-particle emitters are preferably formed over a thin interfacial tunnel oxide layer on the surface of the substrate.
