Obadiah G. IssueVolume: 2026-03-25 Abstract: Understanding how short-range electron transfer generates photocurrent in organic solar cells and what photochemical driving force is needed to maximize efficiencies has been an immensely difficult problem. Here we show how these questions are intertwined: the driving force controls the average charge-transfer distance,最新IF:24.274 官方网址: https://www.nature.com/nchem/ 投稿链接: https://mts-nchem.nature.com/cgi-bin/main.plex , and compare these with free charge yields measured by time-resolved microwave conductivity. We find that the largest driving forces show the shortest charge-separation distances。

并将其与时间分辨微波电导率测量的自由电荷产率进行了比较, 研究组揭示了这些问题的内在关联:驱动力控制着平均电荷转移距离。

The minimum driving force required for efficient charge separation (and minimal voltage losses) is ultimately set by the dielectric constant of the material.
