Photo-thermoelectric energy converter with black-Si absorber

Thermal to electrical energy conversation was increased by ~ 50% by dispersing 50-nm-diameter Au nanoparticles over the black-Si light harvesting surface at an optimized concentration of the Au-colloidal solution. The size of Au nanoparticles corresponds to the extinction maximum at the spectral location of the reflection dip of black-Si substrate. Black-Si… CONTINUE READING
