Due to the dramatic advances in commercial multi-junction solar cells with 40% conversion efficiency, solar concentrator capable of delivering flux levels of hundreds to thousands of suns at high collective efficiency is the key factor for the success of novel Concentrator Photovoltaic (CPV)...

In the concentrated solar power system, the mirror facets of the solar concentrator have to be aligned correctly in order to obtain an optimally focused solar flux at the receiver. In mirror assembly, therefore, it is necessary to develop an accurate, inexpensive and fast measurement method to...

The surface shape and optical quality of the solar concentrators have a great influence on the solar power plant efficiency, and there need an accurate, inexpensive and fast tool to do this measurement work at the plant start up and during operation. The development of the measurement methods of...
