标题： Electromagnetic approach to ultrathin solar cell efficiencies

摘要： 当前评估太阳能电池效率的方法无法应用于极薄的电池，因为在近场光学领域中出现的现象占主导地位。 我们通过基于涨落耗散定理的严格电磁计算来解决这个问题。 我们的方法通过计算具有金背反射器的GaAs太阳能电池在远低于太阳辐射典型波长的厚度下的效率来加以演示。 结果表明，近场光学效应会影响低维太阳能电池的性能。 显示英文摘要

摘要： Current methods for evaluating solar cell efficiencies cannot be applied to extremely thin cells where phenomena from the realm of near field optics prevail. We overcome this problem by offering a rigorous electromagnetic calculation of solar cell efficiencies based on the fluctuation dissipation theorem. Our approach is demonstrated by calculating the efficiency of a GaAs solar cell with an Au back reflector for thicknesses well below the typical wavelength of the solar flux. It is shown that near field optics affect the performance of low dimensional solar cells.
