Traditionally, noble metal cocatalysts are used to increase the activity and selectivity of a photocatalyst. In this work, we systematically investigate different nanomaterials based on the abundant and inexpensive elements Cu and Fe as cocatalysts on TiO₂ (P25) for the photocatalytic hydrogen evolution reaction under simulated sunlight as well as under UV irradiation. All the investigated Cu and Fe sulfides/oxides can be obtained <i>via</i> a simple and fast microwave-assisted synthesis. In addition, we show how further modifications, such as partial oxidation of the sulfides or doping of CuFe₂O₄ with Ni, can have a tremendous effect on the performance as a cocatalyst, increasing the activity by a factor of more than 15 compared to pristine TiO₂ and by a factor of almost 6 compared to TiO₂ equipped with undoped CuFe₂O₄ under AM 1.5G simulated sunlight. Under UV irradiation, an H₂ evolution rate of more than 2.3 mmol h⁻¹ was achieved.

Ferroelectric materials, featuring spontaneous polarization and external-field tunability, offer unique advantages in solar energy conversion. Benefiting from their intrinsic polarization field, ferroelectric materials can efficiently separate photogenerated carriers and generate bulk photovoltaic voltages beyond the bandgap limit. Moreover, by integrating pyroelectric properties, the ferroelectric photovoltaic pyroelectric coupling effect (FPPCE) enables the synergistic regulation of polarization and pyroelectric fields, significantly enhancing carrier separation and transport, thus improving photovoltaic conversion efficiency. This review systematically summarizes the fundamental mechanisms, performance modulation strategies, and potential applications of FPPCE, with a particular focus on the influence of material dimensionality, interface engineering, and stress regulation. The applications of FPPCE in solar devices, self-powered sensors, and smart building systems are also discussed. Finally, future research directions such as machine-learning-assisted material design and multi-coupled energy chemistry are highlighted, aiming to provide new insights for the design and development of high-performance ferroelectric multi-field energy conversion systems.</p>","PeriodicalId":230,"journal":{"name":"Solar RRL","volume":"9 16","pages":""},"PeriodicalIF":6.0,"publicationDate":"2025-07-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144905538","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Existing research has achieved significant enhancement through the development of photothermal materials, but the spatial utilization efficiency of solar energy remains suboptimal.

It couples the 3D hydrogel with a preheating structure composed of a light-absorbing coating and a copper sheet. The experiment has investigated the effects of solar irradiance intensity and preheating structure on evaporation. According to the experimental results, under the solar radiation intensity of only 1 sun, the steam generation amount increases to a maximum of 2.37 kg·m⁻\u0000 ²·h⁻\u0000 ¹. In addition, the preheating structure has a significant effect on improving the evaporation efficiency of the evaporator. Compared with the evaporator without a preheating structure, the maximum enhancement effect can reach 40.1% under the solar radiation intensity of 1 sun. Under a higher radiation intensity, the enhancement effect increases to 43.4%.

Experimental studies show that the DIO solvent additive treatment was beneficial to improve exciton dissociation and balance the charge transport. While the comprehensive analysis of experimental researches also reveals that the DIO solvent additive may go against the charge transport and charge collection to some extent. Overall, DIO addition treatment has a positive effect on the whole photoelectric conversion process for PM6:BTP-eC9-based nonfullerene OSCs.
