Energy conversion, also called energy transformation, is the process of converting energy from one form into another. There are many important categories of light-related energy conversion technology closely relevant to everyday life, such as photovoltaic, electroluminescence, and water photolysis. Many different types of organic or inorganic, microsized or macrosized, low-dimensional or high-dimensional materials have been developed to perform in specific ways in order to meet various needs. Some of these materials were designed at a molecular level in order to achieve energy harvesting or conversion; some were developed as auxiliary additives or dopant materials; and some are used for fabricating high performance devices. Thus, this special issue aims to collect relevant research within the above areas to showcase the current state-of-the art in materials for the production of photoelectricity.

The focus of this special issue is on the development, synthesis, modification, and theoretical study of materials for photoelectric and electrooptical conversion and the applications of these materials in devices. As for photoelectric conversions, the focus will be on third generation solar cells, including dye-sensitized solar cells (DSSCs), perovskite solar cells (PSCs), organic photovoltaic solar cells (OPVs), and quantum dot solar cells (QDSCs). We invite various submissions including original research articles and reviews in this area.

Potential topics include but are not limited to the following:

• Newly developed materials for photoelectric and electrooptical conversion
• Novel synthetic methods or modifications to create materials with desirable properties for photoelectric and electrooptical conversion
• Theoretical studies of materials for photoelectric and electrooptical conversion, especially studies on optimizing material properties
• Novel techniques for analyzing or probing the performance of materials for photoelectric and electrooptical conversion
