Transparent p–n Junction in Cu2O/ZnS/ZnO Core–Shell Nanoarrays via In Situ Sulfuration for Enhanced Photovoltaic Stability

“…9,23−25 Owing to the synergism between the appropriate Fermi level and high QY of the in situ dual functional ZnS transition layer, and the better carrier transport pathway and higher solar efficiency of ZnS/ ZnO orderly core−shell nanoarrays, the photogenerated carrier would attain a decent kinetic equilibrium to achieve high PCE. 9,25,[48][49][50]62 Thus, via modification with the in situ dual functional ZnS transition layer, the as-prepared Cu 2 O/ZnS/ ZnO achieves a good balance between PCE and transparency. 46−48 In addition, the ZnS/ZnO core−shell nanoarrays with high Young modulus can increase the physical stability, and the in situ ZnS shell with high chemical stability can inhibit the surface etching and impurity adsorption of ZnO nanoarrays.…”

“…The exhaustion and shortage of nonrenewable resources have recently emerged as urgent issues; therefore, the discovery and exploration of renewable resources are crucial in solving these issues. − Owing to factors such as the wide range of access channels, sufficient energy reserves, and environmental friendliness, , solar energy-based photoelectric devices have become the most effective and reliable technology to address these issues. − However, current research in the field solar energy-based photoelectric devices is primarily focused on the ultimate goal of enhancing solar efficiency. Moreover, these nontransparent solar cells cannot be used in windows, smart buildings, or automobiles, which restrict their wide applicability. , Therefore, developing transparent photovoltaic devices with balanced photovoltaic conversion and transparency is crucial. − Accordingly, to date, a series of wide bandgap semiconductor photovoltaic devices, such as SnO 2 -based and TiO 2 -based devices, has been developed.…”

“…Moreover, they fabricated vertical ZnO–ZnS arrays with excellent photosensing performances by adjusting shell wall thickness to improve solar efficiency . Further, the sulfuration process can efficiently decrease oxygen vacancy, which can in turn decrease the number of scattering centers, thus inhibiting nonradiative transition. , In addition, the ZnS shell with high chemical stability can provide passivation for inhibiting surface etching and the adsorption of impurities on ZnO nanoarrays, which can enhance photovoltaic stability efficiently. Baranowska-Korczyc et al used ZnS surface passivation for improving the stability of ZnO films …”

Remarkable enhancement of photocatalytic performance in LaCrO3 through a controlled chemical reduction process

“…As reported in the literature, LaCrO 3 is not an efficient photocatalyst because it exhibits intrinsic high charge carrier recombination that severely restricts quantum efficiency, leading to a decrease in HER performance. 46,47 According to our data, creating oxygen vacancies by topotactic reduction favors the separation of electrons from holes, thereby enhancing the photocatalytic HER performance of LaCrO 3 -based materials. This method provides an alternative to the usual doping of A and B sites in perovskite oxide-based materials.…”

CuI/BaSnO3 Quantum Dot/ZnSnO3 Perovskite-based Transparent p–n Junction for Photovoltaic Enhancement

“…With the rapid growth in energy demand and environmental pollution, developing green renewable energy sources has become a crucial research topic. Solar energy, with its abundant reserves, cleanliness, and low cost, has gained considerable attention and has been extensively studied as a promising approach for power generation, − particularly through solar cells owing to their high efficiency and convenience of use. − For example, silicon and perovskite solar cells have shown great potential for development. However, long-term stability and toxicity issues associated with organic and inorganic hybrid perovskite solar cells pose serious challenges for their practical applications. − Moreover, while full-spectrum absorption is advantageous for achieving high photovoltaic conversion efficiency (PCE), it hinders wide-ranging applications, − such as in smart windows.…”
