Organic photovoltaics has drawn immense attraction in recent years due to advancements in development of new materials. Despite the encouraging efficiency boost witnessed, the technology is still lacking behind others, hence the need of new materials design is necessary. However, it is equally important to evaluate and understand the efficiency limiting parameters and improve the characterization methods addressing these. Ultrafast spectroscopy has been utilized to evaluate the exciton generation, recombination, and charge transfer processes, yet the complete picture of the photophysical processes is not known. With this, there is a significant room for improvement and understanding of these critical parameters controlling the efficiency.
The understanding of efficiency limiting processes hampering the solar cell’s figures of merit is vital to improve and provide guidelines for designing new materials. Fabricating highly efficient organic solar cells and providing new characterization directions aiding in evaluating the blend morphology, the alignment of energy levels, and the charge transfer mechanism are crucial. Additionally, examining the photophysics of solar cells is necessary, thus bridging theory and experimental work is a prerequisite to compete with other technologies.
We welcome Original Research, Review, Mini Review and Perspective articles on themes including, but not limited to:
• New polymers
• Applications in solar cells
• Organic-perovskite tandem solar cells
• Charge transfer in polymer based solar cells
• Spectroscopy and efficiency limiting processes in polymer based solar cells.
Keywords:
Keywords polymer, nonfullerene acceptors, photophysics, charge transfer, OPV
Important Note:
All contributions to this Research Topic must be within the scope of the section and journal to which they are submitted, as defined in their mission statements. Frontiers reserves the right to guide an out-of-scope manuscript to a more suitable section or journal at any stage of peer review.
