Obtaining a photomultiplication-type organic photodiode with a high gain–bandwidth product is challenging. We show that a newly designed regioregular polymer enables the formation of a highly oriented face-on structure with a low trap density, leading to a high EQE and a fast response time. As a result, a gain–bandwidth product of over 4 × 10⁵ Hz is achieved.

一种区域规则的供体-受体共聚物，允许在光电倍增型有机光电二极管中获得高增益带宽积

获得具有高增益带宽积的光电倍增型有机光电二极管具有挑战性。我们表明，新设计的区域规整聚合物能够形成具有低陷阱密度的高度取向的正面结构，从而导致高 EQE 和快速响应时间。结果，实现了超过 4 × 10 ⁵ Hz的增益带宽积。
