The development of novel optoelectronic devices is important to achieve sustainability and to improve the technological level of the society. Advanced types of solar cells (such as organic, sensitized and recently perovskite cells, sensitized and not) have been developed with an emphasis on the sustainability and scalability of electricity production, while advanced light-emitting technologies such as OLEDs (organic light emitting diodes) or TTA / TADF (triplet-triplet annihilation / thermally activated delayed fluorescence) based LEDs have been pursued to achieve better performance characteristics as well as scalability and sustainability of production and economic energy use. While the development of materials for these technologies is commonly pursued in different research communities, it faces a set of common challenges, such as achieving of the desired optical properties, band alignment, and electron/hole conductance.

This Research Topic is designed to bring under one roof works aiming at the design and optimization of materials for several solar cell and light-emitting technologies, where similar issues need to be addressed in different technologies, such as the design of optical properties, electron and hole conductance, or achieving good solution processability as well as environmental friendliness and stability and durability under operating conditions. We hope to help cross-fertilization of ideas among these applications. The scope therefore includes materials for perovskite and organic solar cells as well as sensitized solar cells, and materials for organic light emitting diodes. Inorganic solar cells are of interest since they are developed as components of multijunction cells containing perovskites or other advanced solar cells such as quantum dot based solar cells. Experimental studies as well as modelling works are welcome.

Examples of topics include:
- design and/or optimization of device constituent materials such as electron and hole transporting layers, absorbers (chromophores), and selective contacts;
- design and control of the morphology (including interface engineering) and/or crystal structure of the solar cell components;
- characterization of the solar cell materials and components;
- design of emission properties of OLED materials, including optimization of thermal activated delayed fluorescence;
- studies aimed at the enhancement of energy conversion as well as the mitigation of undesired phenomena such as recombination;
- theoretical prediction of yet unexplored and novel materials with potential applicability in PV and emissive devices.

We welcome Original Research papers, Reviews and Brief Research Reports as article types for this collection.


Keywords: perovskite solar cells, organic solar cells, solution-processed solar cells, OLED experiment, modeling
