我们报告的实验结果与一个微型光纤光伏聚光器与（a）可交付的功率密度高达104太阳（10 W/mm 2），（B）太阳能电池效率超过30%，（c）完全被动冷却，（d）均匀和个性化的电池照明，和（e）组装从现成的组件。测量包括串联III-V电池的转换效率对（1）功率输入，（2）通量分布和（3）来自光纤集中器的修改光谱的灵敏度。我们的研究结果预示着这种设计在高达数千个太阳的浓度水平上的可行性。
We report experimental results with a miniature fiber-optic photovoltaic concentrator with (a) deliverable power density up to 104 suns (10 W/mm2), (b) solar cell efficiencies above 30%, (c) completely passive cooling, (d) uniform and individualized cell illumination, and (e) assembly from readily available components. Measurements include the sensitivity of the conversion efficiency of tandem III–V cells to (1) power input, (2) flux distribution, and (3) the modified spectrum from the fiber-optic concentrators. Our results augur favorably for the feasibility of such designs at concentration levels as high as thousands of suns.
