Special Issue Information

Dear Colleagues,

Rapid advancements in nanotechnology have revolutionized the field of photoelectric materials, ushering in a new era of highly efficient and versatile devices, such as solar cells and photoelectrochemical water-splitting applications. Among these, nano–micro materials have emerged as pivotal components, exhibiting exceptional photoelectric properties that are essential in next-generation solar cells and photoelectrochemical applications. In particular, perovskites, nanocrystals (NCs), quantum dots (QDs), and metal–organic frameworks (MOFs) have garnered significant attention due to their unique optical and electronic characteristics. Perovskite/NC/QD/MOF materials, with their outstanding light absorption and charge transport properties, have led to remarkable progress in solar cells and photoelectrochemical applications. The integration of these advanced nano-micro materials into photoelectric devices holds immense potential in addressing global energy challenges and driving sustainable technological development.

This Special Issue will collate pioneering research and developments in the field of photoelectric materials, focusing on their applications in solar cells and photoelectrochemical systems. By bringing together cutting-edge studies and innovative approaches, this collection seeks to highlight the current progress and emerging trends in the use of perovskites, NCs, QDs, and MOFs. The contributions will not only advance the scientific understanding of these materials but also align with the journal's scope of disseminating high-impact research that addresses critical scientific and technological challenges. This Special Issue will serve as a comprehensive resource for researchers and practitioners, fostering collaboration and knowledge exchange in the rapidly evolving field of advanced energy materials.

This Special Issue, "Photoelectric Research in Advanced Energy Materials", will bring together significant contributions from researchers in academia and industry, highlighting advancements in nanomaterial science across various applications. Please join us in this exploration of cutting-edge photoelectric materials and their transformative impact on solar energy and photoelectrochemical technologies.

We look forward to receiving your contributions.

Perovskite-type materials containing Bi3+ cations at A sites are interesting from the viewpoints of applications and fundamental science as the lone pair of Bi3+ cations often stabilizes polar, ferroelectric structures. This can be illustrated by a lot of discoveries of different new functionalities in bulk and thin films of BiFeO3 and its derivatives. In this work, we investigated solid solutions of BiCr1−xFexO3 with 0.1 ≤ x ≤ 0.4 prepared by a high-pressure (HP) method and post-synthesis annealing at ambient pressure (AP). HP-BiCr1−xFexO3 modifications with 0.1 ≤ x ≤ 0.3 were mixtures of two phases with space groups C2/c and Pbam, and the amount of the C2/c phase decreased with increasing x. The amount of the C2/c phase was also significantly decreased in AP-BiCr1−xFexO3 modifications, and the C2/c phase almost disappeared in AP-BiCr1−xFexO3 with 0.2 ≤ x ≤ 0.3. Fundamental, strong reflections of HP-BiCr1−xFexO3 and AP-BiCr1−xFexO3 were almost unchanged; on the other hand, weak superstructure reflections were different and showed clear signs of strong anisotropic broadening and incommensurate positions. These structural features prevented us from determining their room-temperature structures. On the other hand, HP-BiCr1−xFexO3 and AP-BiCr1−xFexO3 showed high-temperature structural phase transitions to the GdFeO3-type Pnma modification at Tsrt = 450 K (x = 0.1), Tsrt = 480 K (x = 0.2), Tsrt = 510 K (x = 0.3), and Tsrt = 546 K (x = 0.4). Crystal structures of the GdFeO3-type Pnma modifications of all the samples were investigated by synchrotron powder X-ray diffraction. Magnetic properties of HP-BiCr1−xFexO3 and AP-BiCr1−xFexO3 were quite close to each other (HP vs. AP), and the x = 0.2 samples demonstrated negative magnetization phenomena without signs of the exchange bias effect.

During the process of producing potassium fertilizer from salt lake resources, a large amount of waste liquid brine, rich in raw materials such as magnesium chloride, is generated. In this work, a MoS2/MgAl-LDH composite material was constructed using the secondary hydrothermal technique. Characterizations including X-ray diffractometer (XRD), scanning electron microscopy (SEM), and X-ray photoelectron spectroscopy (XPS) confirmed the distribution of MoS2 nanosheets on the surface of MgAl-LDH. Under full-spectrum irradiation, the degradation efficiency of Rhodamine B reached 85.5%, which was 69.2% higher than that of MgAl-LDH alone. The results from the electrochemical, UV-Vis, and XPS-VB tests indicate that the internal electric field accelerated the separation and transportation of charge carriers between MoS2 and MgAl-LDH. These findings demonstrate the great potential of MoS2/MgAl-LDH as a photocatalyst in the degradation of organic dyes, which will aid in the green recycling utilization of magnesium resources from salt lake by-products.
