A nanopillar-structured perovskite-based efficient semitransparent solar module for power-generating window applications

Abstract

An efficient large-area semitransparent solar module is demonstrated using a nanopillar perovskite absorber. A 40.8 cm2 semitransparent solar module with a PCE of 9.04%, AVT of 30.2%, and high GFF of 95.6% is obtained.

Solar water splitting exceeding 10% efficiencyvialow-cost Sb2Se3photocathodes coupled with semitransparent perovskite photovoltaics

“…The state-of-the-art Sb2Se3 photocathode was fabricated by employing appropriate junction layers, which significantly enhanced the performance, particularly the longwavelength photon-harvesting capability. For the top perovskite PVs, we employed nanopillar-structured semitransparent PVs 17,18 , which allowed us to precisely control the light absorption and performance of the top electrode, thereby helping to determine optimum transmittance and performance as a complementary top electrode for high ηSTH.…”

The Use of Anodic Oxides in Practical and Sustainable Devices for Energy Conversion and Storage

“…The perovskite-type cells (PSC) are a new generation of solar cells known for their high efficiencies, low-cost, flexibility, and semitransparency, which expand their fields of application [ 26 , 93 ]. These solar cells are composed of an organometal halide perovskite with chemical formula ABX 3 where A = methylammonium or formamidinium; B = Pb or Sn; and X = I, Cl, or Br [ 26 ], but the most common material is Pb [ 26 , 94 ]. Current studies involving PSC and anodic oxides applied the AAO scaffold for the perovskite deposition since the alumina allows the control of the perovskite layer’s spatial distribution and volume, which influences the optical properties, such as transparency and color neutrality [ 26 , 94 ].…”

Recent Progress on Advanced Optical Structures for Emerging Photovoltaics and Photodetectors

“…To realize semitransparency in OPVs and PSCs, one can manipulate the coverage, [ 35–43,161–163 ] thickness, [ 10–17,44–48,164,165 ] or bandgap of the active layer [ 2,8,9,18–24,49,50,166–168 ] or replace the opaque metal electrode with light‐transmitting media (e.g., metal nanowires, [ 44,46,51–56,169–171 ] transparent conducting oxides, [ 43,57–61,167,168,172–180 ] transparent conducting polymers, [ 40,62,63,181–184 ] graphene, [ 54,64,164,185 ] and carbon nanotube [ 65,186–188 ] ). Although the most convenient way to fabricate an ST‐PV is to decrease the thickness of the top metal electrode and, thereby, increase its transparency, [ 35,39,40,47,58,66–72,124 ] there is always a trade‐off between conductivity and transparency.…”
