Design of High Concentration Reflected Photovoltaic Module with Light Guide Tube

A high concentration reflected photovoltaic (HCRPV) has been designed in 3x3 array module with light guide tube. In this paper, the simulation of the HCRPV system and measurement has been conducted. There are two phases for designing the tracking sun position system and getting the maximum peak power output from the solar chips. First, we had simulated the optimal condition of 3x3 array module of high concentration reflected photovoltaic system. The main parameters include the focal length and radius of curvature of the first and secondary mirror, the slope angle and the length of light guide tube. The simulation results of the light collective efficiency can be reached to about 94.8%. After simulation, the HCRPV module was then fabricated using Aluminum material and coated with silver material. The result of output voltage was measured to be 2.46V~2.47V, the output current was measured to be 0.267A~0.269A. The power can be calculated to be about 0.66W~0.67W. The ratio of concentration/power can be calculated to about 117.8~119.5
