Special Issue Information

Photovoltaic technology is the symbol of a sustainable future in many countries around the globe. As a result, numerous investments have been made in research, development, demonstrators, and production lines. No other renewable technology has received such a strong appreciation from the public, politics, and industry. New technologies have traced the way for new materials, products, and additional market segments. Engineering, nanoscience, nanotechnology, and surface science have contributed to introducing new materials and customized processes for solar cell and to developing the sustainable energy sources scenario. In the last decades, many research institutes, companies, and consortia have demonstrated that the new concept of solar cell technology can achieve high performance, large application areas, and industrialization. There are different types of solar devices among the third generation photovoltaics that have recently emerged and their benefits and issues have been exhibited, e.g.: dye-sensitized solar cells, hybrid and organic solar cells, quantum dot solar cells, and perovskite solar cells. This Special Issue aims to be a global reference for research and industrial developments in third-generation photovoltaics. We expect to receive original or review manuscripts that can be of interest and help to researchers, experts, and entrepreneurs.

Perovskite solar cells have achieved remarkable enhancement in their performance in recent years. However, to get an entrance to the photovoltaic market, great effort is still necessary to further improve their efficiency as well as their long-term stability under various conditions. Among various types of approaches (including compositional engineering, dopant engineering, self-assembled monolayers (SAMs), et al.), interfacial engineering through passivation treatment has been considered as one of the most effective strategies to reduce the non-radiative recombination within the PSCs. Thus, this short review summaries recent efforts on chemical interfacial passivation strategies from a different perspective owing to their common phenomena of reconstructing the perovskite surface via the formation of three-dimensional perovskite, low-dimensional perovskite and synergistic effect provided by a mixed-salt passivation system, respectively.

Since the introduction of Perovskite Solar Cells, their photovoltaic efficiencies have grown impressively, reaching over 25%. Besides the exceptional efficiencies, those solar cells need to be improved to overcome some concerns, such as their intrinsic instability when exposed to humidity. In this respect, the development of new and stable Hole Transporting Materials (HTMs) rose as a new hot topic. Since the doping agents for common HTM are hygroscopic, they bring water in contact with the perovskite layer, thus deteriorating it. In the last years, the research focused on “dopant-free” HTMs, which are inherently conductive without any addition of dopants. Dopant-free HTMs, being small molecules or polymers, have still been a relatively small set of compounds until now. This review collects almost all the relevant organic dopant-free small-molecule HTMs known so far. A general classification of HTMs is proposed, and structure analysis is used to identify structure–property relationships, to help researchers to build better-performing materials. Full article
