A type II GaSb quantum ring solar cell is fabricated and measured under the concentrated sunlight. The external quantum efficiency confirms the extended absorption from the quantum rings at long wavelength coinciding with the photoluminescence results. The short-circuit current of the quantum ring devices is 5.1% to 9.9% more than the GaAs reference's under various concentrations. While the quantum ring solar cell does not exceed its GaAs counterpart in efficiency under one-sun, the recovery of the open-circuit voltages at higher concentration helps to reverse the situation. A slightly higher efficiency (10.31% vs. 10.29%) is reported for the quantum ring device against the GaAs one.
制备了一种II型锑化镓量子环太阳能电池，并在聚光太阳光下进行了测量。外部量子效率证实了量子环在长波长处的扩展吸收，这与光致发光结果一致。在不同的聚光条件下，量子环器件的短路电流比砷化镓参考器件高5.1%至9.9%。虽然在标准测试条件下量子环太阳能电池的效率没有超过其砷化镓对应物，但在较高聚光条件下开路电压的恢复有助于扭转这种情况。据报道，量子环器件的效率略高于砷化镓器件（10.31%对10.29%）。
