摘要 以带有中间层的Si基薄膜叠层电池为研究对象,模拟了中间层对入射光在叠层电池中传播和分配的影响,对中间层的材料选择提出了优化方案,并以ZnO作中间层,实验验证了其对入射光的管理作用。模拟结果表明,引入适当的中间层,既能提高短波段的反射率,又能明显增加长波段光的透过率。加入ZnO中间层,可使厚为200nm的顶部非晶硅(a-Si)电池的短路电流提高14.1%。 The influence of interlayer on the transmittion and distribution of the incident light in a-Si/μc- Si tandem solar cells was simulated and realized in experiments. Simulation results indicated the scheme to choose the best interlayer materials in theory. An adequate interlayer could enhance the reflectance in short wavelength range as well as increase the transmittance in long wave range. Using ZnO as the inter- layer, we proved our calculation results and validated its light management effect in fact. Typical ZnO interlayer increased apparently the short current density of the top cell by 14. 1%.
