摘要

InxGa1-xN是制备高效多结(MJ)太阳能电池的极具潜力的材料。由III-V材料组成的MJ太阳能电池的成本高于硅太阳能电池。为了解决成本问题,采用聚光系统,用透镜集中太阳光,从而增加照射在太阳能电池上的太阳光强度。建立了具有聚光器的MJ太阳能电池的仿真模型,以优化电池的高效设计。8个结的效率约为72.79%。并对温度对效率的影响进行了评价。在am1.5下计算每个结的光电流密度和开路电压,并假设每个结都吸收了前一个结没有吸收的太阳光子。

High Efficiency InxGa1-xN-Based Multi-Junction Photo Voltaic Cells with Concentrator
InxGa1-xN has been found to be very potential materials for the fabrication of high efficiency multi-junction (MJ) solar cells. The cost of MJ solar cells composing of III-V materials is higher than that of Si solar cells. To resolve the problem of cost is to employ concentrator systems, which concentrate sunlight with a lens, thereby increasing the intensity of sunlight striking the solar cells. A simulation model is developed which optimizes the design of MJ solar cells with concentrator for high efficiency. An efficiency of about 72.79% is achievable for eight junctions. Also the influence of temperature on efficiency is evaluated. The photocurrent density and open circuit voltage of each junction are calculated under AM 1.5 and it is assumed that each junction absorbs the solar photons that are not absorbed by the preceding one.
