Photocurrent Density Enhancement of DSSC with Existence of ZnO in TiO2 Based Photoanode

Indonesian Journal of Applied Physics, 2023
One of the important components of a dye-sensitized solar cell (DSSC) is photoanode which plays a critical role serving as the center of conversion energy. Photoanode consists of transparent conducting substrate, a semiconductor layer, and dyes molecules

An n-Si/n-Fe2O3 Heterojunction Tandem Photoanode for Solar Water Splitting

CHIMIA, 2013
Few metal oxide photoanodes are able to reduce protons to hydrogen because their conduction band minimum is located at too positive potentials. This can be remedied by biasing the photoanode with a photovoltaic cell placed behind the photoanode.

Metal-free photoanodes for C–H functionalization

Nature Communications, 2023
AbstractOrganic semiconductors, such as carbon nitride, when employed as powders, show attractive photocatalytic properties, but their photoelectrochemical performance suffers from low charge transport capability, charge carrier recombination, and self-oxidation. High film-substrate affinity and well-designed heterojunction structures may address these

Halide Perovskite Integrated Photovoltaic Cathodes Incorporating Pt on ZIF‐8‐Derived Carbon for Solar Hydrogen Production

Advanced Functional Materials, EarlyView.
A low‐Pt catalyst supported on zeolitic imidazolate framework (ZIF‐8)‐derived porous carbon and graphite is integrated with a halide perovskite photovoltaic, yielding cathodes that achieve a high photocurrent density (∼20 mA cm−2) under simulated sunlight and exhibit remarkable stability in acidic media over several days, thereby demonstrating a ...
