Abstract
Abstract Field test for the conversion efficiency determination of high concentrating solar cells with fresnel lenses in a tropical location was conducted at the top of NRRU Science Center Building, Nakhon Ratchasima, Thailand . The seven of square shape of 5.5 x 5.5 mm. mutijunction solar cells were series connected to be a module for total 2 modules. Each cell was fabricated with 200 suns silicon-glass fresnel lens for a concentrating purpose. We also determined the conversion efficiency of 160 watts peak monocrystalline solar cell panel for total 2 panels for a comparing purpose. All of solar cell modules, solar cell panels, pyreheliometer and light sensor were set up on the dual axes sun tracker. Data were gathered every 2 minutes all day from December 2012 to May 2014 via the automatic data logging system. The results have presented that the average conversion efficiencies of high concentrating solar cell module with fresnel lenses and of the 160 watts peak monocrystalline solar cell panels were 18.90 % and 11.36 % respectively, while, the average output powers per unit area of them were 13,503.28 watt/m2 and 85.77 watt/m2 respectively. It is clearly seen that, in terms of conversion efficiency and output power per unit area, the advantage of high concentrating solar cell with fresnel lens module significantly better than the typical monocrystalline solar cell panel. Economical aspect, the dominant of high concentrating solar cell with fresnel lens
