Layered CdTe nanoparticles were deposited on surfaces of n-on-p crystalline Si solar cells. Their short-circuit current and conversion efficiency were enhanced due to the nanoparticle deposition. Measurements of reflectance and external-quantum-efficiency spectra as well as atomic-force-microscope observations implied that the enhancements in cell performances were attributable to textured structures...
The effective removal of nano particles from silicon wafer surface was demonstrated using the self-channeled plasma filament excited by a femtosecond (130 fs) Ti:Sapphire laser (lambdap=790 nm). This process has achieved successfully the removal of 100 nm sized polystyrene latex (PSL) particles from the surface. The photoinduced self-channeled plasma filament in air reached a length of approximately...
