Topic: Photoelectric Conversion Functional Materials: Synthesis, Characterization, and Applications

Photoelectric conversion functional materials are the core of photovoltaic/photoelectric technologies, which can directly convert light energy into electrical energy. At present, multiple generations of material systems have been developed in this field: the first generation is represented by crystalline silicon (Si) materials; the second generation includes thin-film materials such as gallium arsenide (GaAs) and cadmium telluride (CdTe); the third generation is centered on perovskite, which has both high efficiency and low-cost preparation potential. Currently, the efficiency of single-junction perovskite solar cells has exceeded 27%. In addition, new materials such as copper zinc tin sulfur selenide (CZTSSe), antimony sulfoselenide (Sb2(S,Se)3), and silver bismuth sulfide (AgBiS2) have become research hotspots in the field due to their significant advantages of abundant reserves and environmental friendliness. This special issue focuses on the latest breakthroughs in emerging photovoltaic/photoelectric/electro-optical technologies, with an emphasis on the efficient synthesis, advanced characterization techniques, mechanism analysis, and theoretical modeling of various semiconductor materials (including bulk, thin-film, nanocrystals/quantum dots, etc.), as well as strategies for integrating these cutting-edge materials into the design and manufacturing processes of device systems, comprehensively integrating the entire process of material innovation, performance breakthroughs, and high-efficiency device fabrication.

Based on this, we sincerely invite researchers from all over the world to submit original research papers and review articles, to explore in depth the key challenges in the field, and highlight the latest research breakthroughs in the field of photoelectric conversion functional materials. The purpose of this special issue is to promote the basic scientific research and technological maturity of photovoltaic/photoelectric/electro-optical devices (including solar cells, photodetectors, light-emitting diodes (LEDs), lasers, X-ray detection, infrared imaging, etc.), and accelerate their progress towards sustainable, low-cost, and commercially viable solutions.
