研究目的
To develop a novel side-chain hole transporting polymer (PVP-CZ) through Mitsunobu post-functionalization for efficient inverted perovskite solar cells (PVSCs).
研究成果
The Mitsunobu reaction is an effective method for synthesizing side-chain hole transporting polymers like PVP-CZ, which exhibit excellent hole-extracting properties and contribute to high-performance inverted perovskite solar cells. This approach offers a promising pathway for developing novel materials for photovoltaic applications.
研究不足
The study focuses on the synthesis and initial application of PVP-CZ in PVSCs, with potential limitations in scalability and long-term stability under operational conditions not fully explored.
