We demonstrated compact SnO<sub>2</sub>thin films prepared by sinter-less spin-coating processes as an electron selective contact for CH<sub>3</sub>NH<sub>3</sub>PbI<sub>3</sub>-based planar-heterojunction perovskite solar cells (PSCs).
Abstract Cascade charge transfer was realized by a H‐bond linked zinc phthalocyanine/BiVO 4 nanosheet (ZnPc/BVNS) composite, which subsequently works as an efficient wide‐visible‐light‐driven photocatalyst for converting CO 2 into and CH , shown product analysis 13 C isotopic measurement. The optimized ZnPc/BVNS nanocomposite exhibits ca. 16‐fold enhancement in the quantum efficiency compared with reported BiVO nanoparticles at excitation of 520 nm assistance 660 photons.

To rationally design single-atom metal-organic framework (MOF)-involving photocatalysts remains an ongoing challenge for efficient CO2 conversion. Here, cuppy microstructures, consisting of a Ti(IV)-oxo node and three linked carboxylic moieties, in the single-coordination-layer Ti2 (H2 dobdc)3 MOF (NTU-9) are exploited to immobilize abundant single Ni(II) sites (Ni@MOF). The coupling Ni@MOF with BiVO4 (BVO) nanosheets by H-bonding-induced assembly process obtains wide-spectrum 2D...
Solar-driven CO2 reduction by water with a Z-scheme heterojunction affords an avenue to access energy storage and alleviate greenhouse gas (GHG) emissions, yet the separation of charge carriers integrative regulation oxidation activation sites remain challenging. Here, BiVO4 /g-C3 N4 (BVO/CN) as such prototype is constructed spatially separated dual CoOx clusters imidazolium ionic liquids (IL) toward photoreduction. The optimized -BVO/CN-IL delivers ≈80-fold CO production rate without H2...

CuI is used to control the molecular orientation of copper phthalocyanine (CuPc) and modify anodes in organic solar cells based on CuPc/C60. By introducing a buffer between indium tin oxide CuPc, power conversion efficiency significantly enhanced by factor ∼70%. Because strong interactions stacking CuPc molecules changed, resulting ∼65% increase absorption coefficient, larger carrier mobility smoother film surface. The anode work function raised formation dipole layer.
Abstract ZnO thin films prepared by spin-coating of nanoparticles at low temperature were utilized as the electron collection layer in CH3NH3PbI3-based perovskite solar cells having a planar heterojunction structure. The thickness key parameter to determine photovoltaic performance was optimized. highest power conversion efficiency up 13.9% with small hysteretic behavior current–voltage curves achieved under AM 1.5 illumination (100 mW cm−2). ZnO-based devices exhibited significantly...

Abstract Solar driven CO 2 conversion into high-value-added chemicals and energy-rich fuels is one of the promising strategies to tackle global warming address energy-supply crisis. Even though enormous effort has been devoted exploring all sorts homogeneous heterogeneous photocatalysts, current efficiency more importantly selectivity valuable are still rather moderate, thus it desired develop high-efficiency photocatalytic system toward reduction with excellent selectivity.
