Обнадеживающие результаты были получены при следующих параметрах слоев: n(DLC) = 2,4, d(DLC) = 50 нм; и n(PS) = 2.2, d(PS) = 100 нм. Отражение в диапазоне 530–560 нм составляло около 0,5% и минимум отражения расположен в области около 535 нм. В целом в видимом диапазоне 400-700 нм отражение не превосходит величины 2,5%. Было четко показано, что возможно значительно уменьшить отражение (на 34,5%) в видимом диапазоне, тем самым повышая эффективность солнечных элементов.</p></abstract><trans-abstract xml:lang="en"><p>In this paper, when modeling the reflection coefficient based on FDTD simulation, the optimal values for the thicknesses of the porous silicon and diamond-like carbon layers of a two-layer antireflection coating (PS/DLC) were determined. Encouraging results were obtained with the following layer parameters: n(DLC) = 2.4, d(DLC) = 50 nm; and n(PS) = 2.2, d(PS) = 100 nm. Reflection in the range of 530–560 nm was about 0.5%, and the reflection minimum is located in the region of about 535 nm. In general, in the visible range of 400-700 nm, the reflection does not exceed 2.5%. It has been clearly shown that it is possible to significantly reduce reflection (on 34.5%) in the visible range, thereby increasing the efficiency of solar cells.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>антиотражающее покрытие</kwd><kwd>пористый кремний</kwd><kwd>алмазоподобный углерод</kwd><kwd>солнечный элемент</kwd></kwd-group><kwd-group xml:lang="en"><kwd>antireflection coating</kwd><kwd>porous silicon</kwd><kwd>diamond-like carbon</kwd><kwd>solar cell</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Ch.
