The integration of photoelectrochemical photoanodes and solar cells to build an unbiased solar-to-hydrogen (STH) conversion system provides a promising way solve the energy crisis. key point is develop highly transparent photoanodes, while its bulk separation efficiency (ηsep. ) surface injection are as high possible. To resolve this contradiction, first novel CdIn2 S4 /In2 S3 heterojunctions in interior nanosheets designed photoanode with transparency ultrahigh ηsep. up 90%. Furthermore,...
Abstract Perovskite photodetectors with bipolar photoresponse characteristics are expected to be applied in the field of secure optical communication (SOC). However, how realize perovskite photodetector response remains challenging.

Wavelength‐dependent realized based on absorption difference photoactive region different...
Dual-absorber photoelectrodes are attractive candidates for solar water splitting due to their broadened absorption spectrum and improved photovoltage compared single-absorber systems.
An internal electric field with controllable direction and full-space action scope is constructed through gradient Sn-doping into a hematite photoanode, which achieves the highest saturated photocurrent density for gradient-decreasing doping.
Optical wireless communication has garnered significant interest, yet its inherent transparency poses a formidable challenge to ensure security. encryption (OEC) emerges as potential remedy; however, widespread adoption is hindered by intricate design and high operational complexity. Herein, we propose an OEC scenario employing self-powered dual-polarity Dember photodetectors (PDs) composed sandwich configuration of ITO/MASnI3/Ag. The highly manipulated photonic responses (i.e., direct...

Finite-element simulation reveals that a highly...
Dual-absorber photoelectrodes have been proved to possess greater potential than the single-absorber systems in applications of photoelectrochemical (PEC) cells (e.g., solar-driven water splitting); however, mismatching energy bands and substantial carrier recombinations at two absorber interfaces are normally subsistent. Here, we introduce an intermediate layer conformal Al2O3 into silicon/hematite (Si/α-Fe2O3) microwire photoanode for enriching understanding interaction among interlayer,...

The oxygen vacancies (Ov)...
Abstract Photovoltaic devices with nanostructured active layers have attracted considerable attention for their outstanding light‐trapping capability. Although the promise of an efficient light‐conversion, realistic performance is still far from expectation. This because detailed electrical mechanisms seldom been included into design, leading to a substantial discrepancy between prediction and reality. paper reports complete optoelectronic simulation nanowire nanohole solar cells by...
Maximizing the optical absorption of one-dimensional Si nanostructure arrays (1DSiNSAs) is desirable for excellent performance 1DSiNSA-based optoelectronic devices. However, a quite large surface-to-volume ratio and enhanced surface roughness are usually produced by modulation morphology 1DSiNSAs prepared in top-down method to improve their absorption. Surface recombination mainly determined characteristics significantly affects photogenerated carrier collection. In this paper, we...
Hematite (α-Fe2O3) material is regarded as a promising candidate for solar-driven water splitting because of the low cost, chemical stability, and appropriate bandgap; however, corresponding system performances are limited by poor electrical conductivity, short diffusion length minority carrier, sluggish oxygen evolution reaction.
