有机聚合物与无机纳米阵列的界面问题是聚合物/无机纳米阵列太阳电池的重要问题。无机纳米阵列与聚合物之间相溶性差、无机纳米阵列的表面有大量的缺陷或空位，这些问题严重地阻碍了太阳电池中光生激子的分离及电荷的传输。对纳米阵列表面进行有效的修饰是解决上述问题的最佳办法。目前，在聚合物/无机纳米阵列太阳电池的研究中，有效的无机纳米阵列的表面修饰手段缺乏，表面修饰对器件性能影响的物理机理不清楚。本项目拟引入具有单个高能光子激发多激子性能的纳米PbS、PbSe材料、新的表面修饰材料（例如聚合物PFN系列等）及其它一系列表面修饰手段修饰无机纳米阵列表面，减少纳米阵列的缺陷，提高其与聚合物的相溶性，增加太阳电池中光生激子的数量。探索有效提高太阳电池性能纳米阵列表面修饰方法。利用瞬态光荧光谱、X射线（或紫外光）光电子能谱、阻抗分析技术、单电荷传输器件探究纳米阵列的表面修饰对太阳电池性能影响的物理机理及规律。

Important problem of polymer/inorganic nanowire array solar cells is interface problem of organic polymer and inorganic nanowire array. Compatibility between polymer and inorganic nanowire array is poor, and surface of inorganic nanowire array has a lot of defects and vacant sites, these problems severely hamper disassociation of excitons and transfer of charges in solar cells. Effectively modified nanowire array surface is the best way to solve the above problems. Currently, effective means of surface modification of inorganic nanowire array are lack and physical mechanism of the effect of surface modification on the device performance is unclear in research of polymer/inorganic nanowire array solar cells. This project aims to introduce nano-PbS, PbSe material, which possess the property that a single high energy photon excites multiple Excitons, and new surface modification materials (such as polymer PFN series), and a range of other means of surface modification, modifying surface of inorganic nanowire array, reducing defects of nanowire array, enhancing compatibility between inorganic nanowire array with polymer and the number of photo-excitons in. solar cells. The effective method of surface modification of nanowire array improving the performance of solar cell will be explored. The physical mechanism and regularity affecting property of solar cells by surface modification will be researched by transient photoluminescence spectroscopy, x-ray (or UV ray) photoelectron spectroscopy, impedance analysis techniques, a single charge transfer device.
