“…Thus, a wavelength-selective intermediate reflector is required to maximize the light-trapping benefits of a textured surface. A large body of work has been published on light-trapping in micromorph Si cells (a thin-film tandem of α-Si:H and µc-Si:H), which are typically deposited onto textured substrates with sub-wavelength features [13][14][15][16][17][18]. Combining a selective intermediate reflector (IR) with these surfaces can provide significant light-trapping in the top cell.…”

Perovskite-on-silicon tandem solar cells show potential to reach > 30% conversion efficiency, but require careful optical control. We introduce here an effective light-management scheme based on the established pyramidal texturing of crystalline silicon cells. Calculations show that conformal deposition of a thin film perovskite solar cell directly onto the textured front surface of a high efficiency silicon cell can yield front surface reflection losses as low as 0.52mA/cm(2). Combining this with a wavelength-selective intermediate reflector between the cells additionally provides effective light-trapping in the high-bandgap top cell, resulting in calculated absolute efficiency gains of 2 - 4%. This approach provides a practical and effective method to adapt existing high efficiency silicon cell designs for use in tandem cells, with conversion efficiencies approaching 35%.

“…Herein we present a more uniform solution whereby a conducting Bragg reflector composed of alternate layers of SiO 2 nanoparticles and sputtered tin‐doped indium oxide (ITO) is employed as the counter electrode for DSCs. These conducting 1D photonic crystals, referred to as selectively transparent and conducting photonic crystals (STCPCs) can be utilized as intermediate reflectors in micromorph Si solar cells; theoretical studies show that STCPC intermediate reflectors can boost the photocurrent in micromorph cells by more than 20% . Their remarkably high conductivity is the result of the alternating porous silica nanoparticle film being partially infiltrated by the ITO, enabling their use as a replacement for the usual FTO‐glass counter electrode.…”

“…20 They can shield part of UV light and most of NIR light. 25 Due to the vast difference between the refractive index of PVC and Sb 2 O 3 , Sb 2 O 3 particle is eligible for all of the light shielding function. 21 UV326 is one of the UV absorbers, which can absorb UV light and keep high transmittance in visible and infrared light region.…”

In this work, some additives were added into plasticized poly(vinyl chloride) (PVC) matrix for the purpose of shielding ultraviolet light (UV), high-energy visible light (HEV) and near-infrared light (NIR). Furthermore, the flame retardance of the plasticized PVC films were also enhanced by adding organo-phosphorus flame retardant plasticizer such as tris(1-chloropropan-2-yl) phosphate (TCPP). The properties of PVC films were investigated by the limiting oxygen index (LOI) test and ultraviolet-visible-near-infrared (UV-vis-NIR) spectrophotoscopy. With the incorporation of Sb 2 O 3 and polyester plasticizer (PEP) into the PVC films, the resultant LOI was increased from 26% (LOI value of PVC with PEP) to 32% (LOI value of PVC with PEP/Sb 2 O 3 ), while the transmittance of visible light decreased from 84.84% to 0.18%. The replacement of PEP in PVC films by TCPP resulted in a significant improvement in flame retardancy. The LOI increased from 26% (LOI value of PVC with PEP) to 35% (LOI value of PVC with TCPP), and the transmittance increased from 84.84% to 91.79%, respectively. Hence, a flame retardant functional PVC film was achieved by the combination of a UV absorber, pigment yellow, TCPP and indium tin oxide (ITO), which possesses a high LOI value (35%), high transmittance in the visible region (81.56%) and low transmittance in the UV region (0.40%), HEV region (62.79%) and NIR region (39.04%).
