About this Research Topic
Organic photovoltaic (OPV) technology has seen a rapid evolution over the last decade, based on comprehensive understanding of the physics and chemistry of fundamental mechanisms and working principles of the device, development of characterization, engineering and processing techniques, implementation of high efficiency materials, introduction of novel contexts and concepts for efficient design and light management, and progress of machinery and printing methods. The unique selling points of OPVs, such as excellent light harvesting capability, freedom of form, color and transparency, environmental friendliness, easy scalability and lower manufacturing costs based on roll-to-roll printing methods, position this technology for the mobile power market, and this most properly reflects the state of the art in commercialization. A certified power conversion efficiency of over 16 %, recently reported by J. Hou et al, has further reduced the performance-gap between OPVs and other technologies such as Si or Perovskite PVs. To achieve the ultimate performance potential of OPVs, however, there is still a plenty of room for improvement through various strategies.
This call for papers is open to all interested applicants to submit an Original Research, Review or Mini Review article focused on the recent advances and the following issues and challenges in the field of solution-processable as well as thermally-evaporated OPVs:
- Novel materials design, device engineering, and fine-control of the morphology;
- Light management;
- Implementation of advanced approaches such as tandem and ternary solar cells;
- Green formulation and eco-friendly processing;
- Scale-up production methods;
- Theoretical calculation/simulation;
- Effective strategies for reducing the fabrication and maintenance costs of the panels and their recycling;
- Investigation and prolonging the photo- and thermal-stability of OPVs; and
- Reliable packaging.
