A high value of reflectivity arises from a high refractive index of the base material of the solar cell, which causes a significant percentage of the incident solar radiation to be reflected at the interface between the surface of the solar cell and the air.
Instead of using the conventional parallel stacking tandem, we report here a reflective tandem configuration, with the perovskite solar cell acting as the spectral filter that absorbs high energy photons, while sub-bandgap photons are reflected to a Si sub-cell using a highly reflective back metal electrode.
According to the SCAPS simulations, the efficiency of the CeO 2 /MOF thin film coated solar cell as an anti-reflective layer increases from 13.77 to 21.92% compared to the uncoated solar cell, resulting in a total efficiency increase of 8.15%.

An anti-reflection (AR) coating is an important component for reducing reflection loss, increasing absorption, and improving the power conversion efficiency (PCE) of a solar cell. Some researchers have therefore implemented single- and double-layer AR coatings into solar cells to reduce the reflection loss .
When coupled with AM 1.5G solar radiation, the reflectance of the perovskite solar cell corresponds to a photon current of 14.8 mA cm −2, slightly higher than the 14.6 mA cm −2 obtained in transmittance mode.
However, it gave almost zero reflection for a wide range of wavelengths, acting as a perfect absorbent, meaning that it can be recommended for a broadband high-performance solar cell. The second and third structures gave good results for a wide range of wavelengths.

To overcome this, textured anti-reflective coatings (ARCs) can be used on top of the finished cell, with textured polydimethylsiloxane (PDMS), a promising candidate. In this work, we vary the texture geometry and film thickness of PDMS anti-reflective foils to understand the effect of these parameters on reflectance of the foil.

Anti-reflection and self-cleaning applications are available in the literature together or separately. The applications on the solar cell are only anti-reflective, whereas applications on the cover glass can be both anti-reflective and self-cleaning. The sol-gel method is the easiest and fastest, dating back to 1864 (Ebelmen, 1946).
