Efficiency Improvement of Cross-Compound Parabolic Concentrator for Silicon and Dye-sensitised Solar Cells
… device fabricated in the laboratory. A cross-compound parabolic concentrator (CCPC) with a 3.61× concentration ratio was integrated with third-generation dye-sensitised solar cells (DSSCs) by directly synthesising the solar cell onto the concentrator’s receiver. Initially, to assess the impact …

Design of inflatable solar concentrator
Solar concentrators improve the performance of solar collection systems by increasing the amount of usable energy available for a given collector size. Unfortunately, they are not known for their light weight and portability, which is ideal for basic applications like solar cooking. The goal of the …

Silicon concentrator cells in a two-stage photovoltaic system with a concentration factor of 300x
In this work a rear contacted silicon concentrator cell was developed for an application in a two stage concentrator photovoltaic system. This system was developed at Fraunhofer ISE some years ago. The innovation of this one-axis tracked system is that it enables a high geometrical concentration of …
