摘要: The mismatch in film thickness and incident angle between reflectance and transmittance extrema due to the presence of lossy film(s) is investigated toward the maximum transmittance design in the active region of solar cells. Using a planar air/lossy film/silicon double-interface geometry illustrates important and quite opposite mismatch behaviors associated with TE and TM waves. In a typical thin-film CIGS solar cell, mismatches contributed by TM waves in general dominate. The angular mismatch is at least 10° in about 37%-53% of the spectrum, depending on the thickness combination of all lossy interlayers. The largest thickness mismatch of a specific interlayer generally increases with the thickness of the layer itself. Antireflection coating designs for solar cells should therefore be optimized in terms of the maximum transmittance into the active region, even if the corresponding reflectance is not at its minimum. 其他題名: Opt Lett 出版者: United States 出版日期: 2013-09-01 出處: Optics letters, 2013-09, Vol.38 (17), p.3257-3260 資源來源: Optica Publishing Group Journals 識別號: ISSN: 0146-9592 識別號: ISSN: 1539-4794 識別號: EISSN: 1539-4794 識別號: DOI: 10.1364/OL.38.003257 識別號: PMID: 23988928
