Title
Metal-Black Scattering Centers To Enhance Light Harvesting By Thin-Film Solar Cells
Abstract
Small metal particles are investigated as scattering centers to increase the effective optical thickness of thin-film solar cells. The particular type of particles used is known as "metal-black", well known as an IR absorber for bolometric infrared detectors. Gold-black was deposited on commercial thin-film solar cells using a thermal evaporator in nitrogen ambient at pressures of ∼1 Torr. A broad range of length scales, as revealed by scanning electron microscope images gives rise to effective scattering over a range of wavelengths across the solar spectrum. The solar cell efficiency was determined both as a function of wavelength and for a solar spectrum produced by a Xe lamp and appropriate filters. Up to 20% increase in short-circuit photo-current, and a 5% increase in efficiency at the maximum power point, were observed. © 2011 SPIE.
