研究目的
Summarizing the recent developments in BDD-based photovoltaic materials, focusing on the chemical structure-property relationships and perspectives on future development.
研究成果
BDD-based polymers are high-efficiency donors for application in OPVs with fullerene or nonfullerene acceptors and play a very important role in promoting the research progress of OPVs. The review suggests several approaches for the design and synthesis of outstanding high-performance BDD-based polymer donor materials, including the design of simple molecular structures, the choice of narrow bandgap nonfullerene acceptors, and the terpolymerization strategy.
研究不足
The review highlights the challenges in further increasing the power conversion efficiency (PCE) of OPVs by boosting the photocurrent while maintaining a high voltage output. It also mentions the need for simple molecular structures and fewer synthetic steps to reduce the cost of materials for large-scale commercial applications.
