Effects of layered CdTe nano particles on Si solar cells

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 of the deposited nanoparticle layers.
