A thin-film GaAs/AlGaAs rear-heterojunction photonic power converter with a back reflector is presented by Henning Helmers and co-workers in article number 2100113. Photon recycling is leveraged to increase the excess carrier density and consequently the output voltage. Optical resonance yields highest absorptance for near-bandgap photons. Thereby thermalization losses are minimized without compromising minimal transmission. A photovoltaic conversion efficiency of 68.9% for 858 nm monochromatic light is demonstrated.

通过光子回收和光学共振实现 68.9% 的高效 GaAs 光子能量转换

Henning Helmers 及其同事在文章编号 2100113 中介绍了一种具有背反射器的薄膜 GaAs / AlGaAs 后异质结光子功率转换器。利用光子回收来增加多余的载流子密度，从而增加输出电压。光学共振对近带隙光子产生最高的吸收率。从而在不影响最小传输的情况下最小化热化损失。证明了 858 nm 单色光的光伏转换效率为 68.9%。
