Enhanced Photoelectrochemical Water Oxidation Using TiO-CoO p-n Heterostructures Derived from in Situ-Loaded ZIF-67.

Exposing catalytically active metal sites in metal-organic frameworks (MOFs) while maintaining porosity is beneficial for increasing electron transport to achieve better electrochemical energy conversion performance. Herein, we propose an in situ method for MOF formation and loading onto TiO nanorods (NR) using a simple solution-processable method followed by annealing to obtain TiO-CoO. The as-prepared TiO-ZIF-67 based photoanodes were annealed at 350, 450, and 550 °C to study the effect of carbonization on photo-electrochemical water oxidation.

Effect of Metal-Precursor Stacking Order on Volume-Defect Formation in CZTSSe Thin Film: Formation Mechanism of Blisters and Nanopores.

In this study, we investigated the effect of the stacking order of metal precursors on the formation of volume defects, such as blisters and nanopores, in CZTSSe thin-film solar cells. We fabricated CZTSSe thin films using three types of metal-precursor combinations, namely, Zn/Cu/Sn/Mo, Cu/Zn/Sn/Mo, and Sn/Cu/Zn/Mo, and studied the blister formation. The blister-formation mechanism was based on the delamination model, taking into consideration the compressive stress and adhesion properties.

Enhanced photovoltaic performance of novel TiO2 photoelectrode on TCO substrates for dye-sensitized solar cells.

In this study, we report synthesis and growth of rutile-anatase TiO2 thin film on fluorine-doped tin oxide (FTO) glass by a two-step hydrothermal method. The effects of additional treatments (i.e.

Molecular design and photovoltaic performance of organic dyes containing phenothiazine for dye-sensitized solar cells.

We synthesized novel organic photosensitizers based on fluorine-substituted phenothiazine with thiophene bridge units in the chromophore for application in dye-sensitized solar cells (DSSCs). Furthermore, organic dyes with different acceptors exhibited higher molar extinction coefficients, and better light absorption at longer wavelengths. The photovoltaic properties of organic dyes composed of different acceptors in their chromophores were measured to identify their effects on the DSSC performance.
