| 中文摘要 | concentrated photovoltaic systems (cpvss) draw more and more attention because of high photovoltaic conversion efficiency, low consumption of solar cell, and low cost of power generation. however, the fallibility of the tracker in such systems has hindered their practical application for more than twenty years. the tracker is indispensable for a cpvs since only normal-incident sunlight can be focused on the solar cell chips, even a slight deviation of incident light will result in a significant loss of solar radiation, and hence a distinct decrease in electricity output. generally, the more accurate the tracker is, the more reliable the system is. however, it is not exactly the case for a cpvs reliability, because the more accurate the tracker is, the better environment it demands. a cpvs is usually has to subjected to harsh environmental conditions, such as strong wind, heavy rain or snow, and huge changes of temperature, which leads to the invalidation of the system's high-accuracy tracker. hence, the reliability of a cpvs cannot be improved only by enhancing the tracker's accuracy. in this paper, a novel compound concentrator, combination of fresnel lens and photo-funnel, has been adopted in a prototype cpvs. test results show that the compound concentrator can relax the angle tolerance from one tenth to five degrees of arc at 400 suns, which can help a cpvs endure serious environment and remain its reliability over long period. the cpvs with compound concentrator is attractive for commercial application. |
