Current Status and Future of Organic–Inorganic Hybrid Perovskites for Photoelectrocatalysis Devices

Abstract

Given the importance of positive impacts on the environment, it is necessary to evaluate the progress made thus far with water-splitting or electrocatalysis devices. Thus, this review aims to provide a broad picture of artificially developed hybrid materials, including organic (macro)­molecules and perovskites, that can function in a synergistic manner and catalyze water-splitting events. This review highlights efficient hybrid organic–inorganic molecular systems integrated within an electrocatalysis device for the purpose of extracting energy from water, by splitting it in a cheaper way, with less energy input to initiate the pathway. The following review will highlight a large number of organic (macro)­molecules, such as oligomers, polymers, and metal–organic frameworks, that have been introduced as tandem layers within a water-splitting device. The organic tandem layer is supposed to provide extra stability and enhance the photocatalytic activity. The review also discusses the drawbacks of existing devices based on hybrid organic–inorganic molecular systems to show what improvements are needed and what could be the future of these eco-friendly devices in a sustainable society on Earth and beyond.

Review on CO2 Management: From CO2 Sources, Capture, and Conversion to Future Perspectives of Gas-Phase Electrochemical Conversion and Utilization

“…C and O in the resulting chemicals in eq are commonly 1 to 3 (C 1 –C 3 products) and 0 to 2, respectively. The chemical products could be obtained on various transition-metal-based catalysts, metal–organic frameworks, organic mediators, MXenes, or carbon-based materials. ,,− …”

Advancements in Photovoltaic Cell Materials: Silicon, Organic, and Perovskite Solar Cells

“…By combining layers of different photovoltaic materials, each tuned to absorb a specific segment of the solar spectrum, tandem cells can convert a broader range of the solar spectrum into electrical energy. This composition often involves inorganic/organic, inorganic/perovskite, and organic/perovskite combinations, each offering unique synergistic benefits [ 158 ].…”

“…Single-junction cells, constrained by the Shockley–Queisser limit, can only convert a fraction of the solar spectrum to electricity due to their fixed bandgap, which limits the range of photon energies that they can effectively absorb. Tandem solar cells, by contrast, are engineered to harness a broader spectrum of solar radiation by stacking multiple photovoltaic layers, each with a different bandgap, in a single device [ 157 , 158 ]. This configuration allows each layer to absorb different segments of the solar spectrum more efficiently than a single-junction cell could.…”

“…Inorganic/organic tandem solar cells combine the high stability and efficiency of inorganic materials with the flexibility and tunable absorption spectra of organic compounds [ 158 ]. Inorganic materials, such as silicon or gallium arsenide, have well-established manufacturing processes and excellent electrical properties but are limited by their rigidity and high manufacturing costs.…”

“…Nanosized TiO 2 with modifiers exhibit a notable photocatalytic reaction toward hydrogen production, CO 2 reduction, nitrogen fixation, or pollutant removal. Kumar et al reviewed efficient hybrid organic–inorganic photocatalysts based on perovskites. They highlight a large number of organic (macro)­molecules, such as oligomers, polymers, and metal–organic frameworks.…”
