NEW LIGHT MANAGEMENT CONCEPTS FOR STANDARD SI SOLAR CELLS FABRICATED BY EMBOSSING OF POLYCARBONATE FRONT BACK SHEETS

摘要

In this article the design, realization and the performance evaluation of optical structures in solar modules arepresented. The work aims on redirecting light within a PV module to avoid light loss due to reflections on themetallization grid and the interspace regions between the single cells. A ray tracing software was used to designstructures which can be implemented by hot embossing into the front and back sheet of a polycarbonate based solarmodule. Based on the simulation results test modules were fabricated and characterized by means of I-Vmeasurements. The results show the usability of ray tracing software for light management purposes in solar modulesand point toward a low cost performance improvement for solar modules.
