近年来，纳米粒子增强的薄膜太阳能电池引起了科学界的广泛关注。为了提高这种电池的性能，系统地研究了纳米颗粒材料对增强效率的影响。在优化纳米粒子阵列参数的基础上，讨论和分析了纳米粒子材料的色散和耗散对光活性层光吸收的影响。最后，它表明，使用介电纳米粒子可以导致类似的，甚至更高的增强相比，金属纳米粒子。
Recently, thin film solar cells enhanced by nanoparticles have attracted much attention of the scientific community. To improve the performance of such cells, a systematic study on the influence of the nanoparticle material on the efficiency of the enhancement is performed. Based on optimization of the nanoparticle array parameters, the role of dispersion and dissipation of the nanoparticle material is discussed and analyzed with respect to optical absorption of the photoactive layer. Finally, it is demonstrated that the use of dielectric nanoparticles can lead to similar and even higher enhancements compared to that of metal nanoparticles.
