A tapered dielectric waveguide solar concentrator for a compound semiconductor photovoltaic cell
Park, Minkyu,Oh, Kyunghwan,Kim, Jeong,Shin, Hyun Woo,Du Oh, Byung The Optical Society 2010 Optics express Vol.18 No.2
<P>A novel tapered dielectric waveguide solar concentrator is proposed for compound semiconductor solar cells utilizing optical fiber preform. Its light collecting capability is numerically simulated and experimentally demonstrated for feasibility and potential assessments. Utilizing tapered shape of an optical fiber preform with a step-index profile, low loss guidance was enhanced and the limitation in the acceptance angle of solar radiation was alleviated by an order of magnitude. Using a solar simulator the device performances were experimentally investigated and discussed in terms of the photocurrent improvements. Total acceptance angle exceeding +/- 6 degrees was experimentally achieved sustaining a high solar flux.</P>
