Abstract Sb 2 S 3 is a promising environmentally friendly semiconductor for high performance solar cells. But, like many other polycrystalline materials, limited by nonradiative recombination and carrier scattering grain boundaries (GBs). This work shows how the GB density in films can be significantly reduced from 1068 ± 40 to 327 23 nm µm −2 incorporating an appropriate amount of Ce 3+ into precursor solution deposition. Through extensive characterization structural, morphological,...
Abstract Three‐dimensional SnO 2 /α‐Fe O 3 semiconductor hierarchical nanoheterostructures were synthesized for photocatalysis through a low‐cost and environmentally friendly hydrothermal strategy, by crystallographic‐oriented epitaxial growth of on three‐dimensional α‐Fe flowerlike nanostructures. In this photocatalyst, visible‐light‐active Fe nanostructures used as medium to absorb photons convert them into photogenerated charges, nanoparticles charge collectors transport the charges. The...

Abstract As an emerging earth‐abundant light harvesting material, antimony selenosulfide (Sb 2 (S,Se) 3 ) has received tremendous attention for photovoltaics. Manipulating the carrier separation and recombination processes is critical to achieve high device efficiency. Compared conventional planar heterojunction (PHJ), bulk (BHJ) configuration affords great potential enable efficient charge extraction.

Carbon nanotubes (CNTs) have attracted much interest because of their special physicochemical properties. Herein, O2 plasma-treated CNTs (denoted as PS-CNTs) are incorporated within a TiO2 matrix PS-CNTs/TiO2) photoanodes in dye-sensitized solar cells (DSSCs). The PS-CNTs/TiO2 composites provide more uniform holes and rough surface over the photoanode also greater degree dye adsorption lower levels charge recombination, compared to either chemical modified CNTs/TiO2 CM-CNTs/TiO2) or alone....

As a revolutionary photovoltaic technology, the perovskite solar cell has received enormous attention, owing to excellent electronic and optical properties of materials. The mesoporous TiO2 (m-TiO2) framework is extensively used as an electron transport layer (ETL) construct high-performance cells (PSCs), showing efficient extraction capability, enlarged perovskite/ETL interface. However, ETL usually involves high-density oxygen vacancies, low mobility, relatively high photocatalytic...
