项目摘要

The main objective of this project is to overcome the low conductivity problem by developing photoconductive materials for the application as interlayers in optoelectronic devices, especially in polymer solar cells. Photoconductive materials proposed here are the composite of inorganic semiconductors like zinc oxide and titanium dioxide and organic photosensitizers, in particular perylene bisimide dyes, and the enhanced conductivity is based on the photo-induced electron transfer from organic dyes to the inorganic semiconductor. The energy level alignment between the inorganic semiconductor and organic dye molecule is essential for the photo-induced electron transfer between them. The interaction between the organic molecule and the inorganic semiconductor must suppress intermolecular interactions between molecules of one type to avoid the possible phase separation, and thus obtain a molecularly dispersed doping system. Thus, the molecular design for the energy level alignment and also for the proper interactions is the essential step. The optimization of the doping concentration of the composite materials and the device engineering will be then pursued in this proposal. Accordingly, the materials synthesis and device fabrication comprise the major two objectives of this project that will be explored in two research groups in Germany and China, respectively.

该项目的主要目标是通过开发光电导材料作为光电器件，特别是聚合物太阳能电池的中间层来克服低电导率问题。本文提出的光导材料是无机半导体如氧化锌和二氧化钛与有机光敏剂，特别是二萘嵌苯双酰亚胺染料的复合物，并且增强的导电性是基于从有机染料到无机半导体的光诱导电子转移。无机半导体和有机染料分子之间的能级对准是它们之间光诱导电子转移的必要条件。有机分子和无机半导体之间的相互作用必须抑制一种类型的分子之间的分子间相互作用，以避免可能的相分离，从而获得分子分散的掺杂体系。因此，能级排列和适当相互作用的分子设计是必不可少的一步。然后，在该提案中将追求复合材料的掺杂浓度和器件工程的优化。因此，材料合成和器件制造构成了该项目的两个主要目标，将分别在德国和中国的两个研究小组中进行探索。
