Аннотация

We theoretically investigate the anti-reflection (AR) films based on nano multi-layers (NML) of TiO <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sub> and SiO <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sub> . This kind of NML dielectric structures have the advantages of low-cost and flexible. Six kinds of transparent conductive substrate (TCS) have been studied here, which are ITO (indium tin oxide) glass, FTO (fluorine-doped tin oxide) glass, ITO PEN (polyethylene naphthalate), FTO PEN, ITO PET (polyethylene terephthalate), and FTO PET, respectively. The AR effect is about 2.3825% for FTO glass substrate, about 3.4232% for ITO glass substrate, about 5.2703% for FTO PEN substrate, about 5.0914% for ITO PEN, about 3.8584% for FTO PET, and about 4.2371% for ITO PET. In practice, this kind of AR films can be widely applicable to enhance the external quantum efficiency (EQE) of the solar cells, and then improve the power conversion efficiency (PCE). Finally, the improved PCE of perovskite solar cells based on our NML AR films is theoretically obtained.
