“…The wide band gap (3.69 eV) PbTiO 3 exhibits a strong inversion symmetry breaking due to its spontaneous electric polarization, and related band bending promotes the separation of photo-excited charge carriers [189,190]. Do et al successfully employed a TiO 2 /PbTiO 3 mixture as a buffer layer in DSSC, improving the DSSC PCE to 8.39% [191]. Ferroelectric PbTiO 3 reduces the defect density at the interface that facilitates the electron transfer for enhanced DSSC performance.…”

Since its discovery, the dye-sensitized solar cell (DSSC) technology with its low-cost, simple fabrication procedure and promising photovoltaic (PV) performance remains a fertile research topic. Most DSSC research is focused on the TiO2, ZnO and other binary metal oxides based photoelectrodes and costly platinum (Pt) based counter electrodes (CEs). However, the overall PV performance of these traditional DSSCs is still inadequate compared to other standard PV technologies. The nanostructured perovskite oxides (POs) with their easily tunable interesting photophysical properties, higher stability, relatively simple synthesis procedure and high PV performance emerge as the promising alternatives for the binary metal oxide-based photoelectrodes and costly Pt-based CEs. Though there has been significant improvement in inorganic PO photoanode and CE based DSSCs in the last decade, a combined report on it is still missing. This review reports the underlying mechanisms, latest advances, and prospects of the PO photoanodes and CEs, with a particular focus on PO-based transparent conductive electrodes. We have summarized the shortcomings of the conventional DSSCs and highlighted the potentials of POs to overcome those limiting factors, which will guide the rational design of a highly efficient, cost-effective, and stable DSSC.

“…The valence band top edge should be more positive in reduction potential to generate O 2 from H 2 O and the bottom energy level of the conduction band should be more negative with respect to the reduction potential of CO 2 in order to produce CH 4 . 23 The band gaps of AEM@GeZnS, Pd@GeZnS and Au@GeZnS were determined to be 2.8, 2.6 and 2.5 eV, respectively by UV-vis absorption spectra. The position of the conduction band of the photocatalyst could be estimated using the Mulliken electronegativity method.…”

Open framework metal chalcogenides as efficient photocatalysts for reduction of CO₂into renewable hydrocarbon fuel

et al. 2016

Open framework metal chalcogenides are a family of porous semiconducting materials with diverse chemical compositions. Here we show that these materials containing covalent three-dimensional superlattices of nanosized supertetrahedral clusters can function as efficient photocatalysts for the reduction of CO2 to CH4. Unlike dense semiconductors, metal cations are successfully incorporated into the channels of the porous semiconducting materials to further tune the physical properties of the materials such as electrical conductivity and band gaps. In terms of the photocatalytic properties, the metal-incorporated porous chalcogenides demonstrated enhanced solar energy absorption and higher electrical conductivity and improved photocatalytic activity.

Enhanced Efficiency and Stability of Inverted Perovskite Solar Cells Using Highly Crystalline SnO₂ Nanocrystals as the Robust Electron‐Transporting Layer

Highly crystalline SnO2 is demonstrated to serve as a stable and robust electron-transporting layer for high-performance perovskite solar cells. Benefiting from its high crystallinity, the relatively thick SnO2 electron-transporting layer (≈120 nm) provides a respectable electron-transporting property to yield a promising power conversion efficiency (PCE)(18.8%) Over 90% of the initial PCE can be retained after 30 d storage in ambient with ≈70% relative humidity.
