Topic: Emerging Photovoltaics: From Materials to Device

Physics and Characterization

Special Topic Introduction

The continuous development of photovoltaic technologies provides opportunities for improving solar energy conversion
efficiency, stability, and practical applicability. This Special Issue focuses on recent advances in emerging photovoltaic
systems, including perovskite solar cells, organic solar cells, and inorganic thin-film solar cells, with an emphasis on
photovoltaic materials, interface engineering, device optimization, and the understanding of underlying mechanisms.

The articles collected in this Special Issue cover several important aspects of photovoltaic research, including the
development of perovskite solar cells for specific application scenarios, optimization of device performance through additive
engineering and machine learning-assisted approaches, molecular and interfacial modification strategies for enhancing
organic photovoltaic devices, as well as compositional and doping regulation of antimony-based thin-film solar cells to
improve charge transport and photovoltaic performance.

By combining perspectives from materials science, chemistry, and device physics, this Special Issue provides insights into
the relationship between material design, interface properties, and device performance. The collected studies contribute to
a better understanding of emerging photovoltaic technologies and offer useful strategies for the development of efficient,
stable, and sustainable solar energy conversion systems.
