PTO2 宽禁带客体给体使三元全聚合物太阳能电池效率达 19.12%
Guest Donor With High Electrostatic Potential Enables Low‐Energy‐Loss Ternary All‐Polymer Solar Cells
AI 导读
研究者在 PM6:PYIT 体系中引入宽禁带、能级更深的客体给体 PTO2，三元全聚合物太阳能电池效率达到 19.12%，开路电压提升至 0.963 V，且未牺牲短路电流密度与填充因子。
推荐理由
原文给出宽禁带客体给体 PTO2 的静电势调控思路，读者可据此理解三元全聚合物太阳能电池降低能量损失的匹配策略。
创新点
用静电势更负的宽禁带客体给体与表面静电势为正的受体配对，构建分子间电场以促进激子解离，在保持短路电流密度和填充因子的同时降低能量损失、提升开路电压。
