Abstract
Fluorescent collectors have been considered for being used as a light concentrator in photovoltaic applications. It is able to replace the expensive area of solar cells in order to minimize the energy cost. In this study, fluorescent collectors integrated with microlens arrays were developed in order to improve the collection efficiency. Fluorescent collectors were prepared by casting an epoxy resin solution containing Rhodamine 6G dye in the polydimethylsiloxane master mold. Polydimethylsiloxane-based microlens arrays with actual diameters of 804.06-1008.02 μm were fabricated using a replica molding technique. The microlens arrays were then integrated with the fluorescent collectors with various dye concentrations from 2.5 × 10-4 to 4.5 × 10-4 Molar. Experimental results were demonstrated that the implementation of polydimethylsiloxane microlens arrays on the top of fluorescent collectors was improved for both light absorption and fluorescent intensity.
