Professor Wei Zhan of Auburn University is supported by the Macromolecular, Supramolecular and Nanochemistry (MSN) Program in the Division of Chemistry to develop a new class of molecular photovoltaic systems using chromophores (porphyrins), electron acceptors (fullerenes) and donors (ferrocenes) assembled within solid-supported thin lipid bilayer films. Organothiol adsorbates on gold will be used to adjust the surface properties of the solid support including polarity, charge, work function, redox properties, and degree of electronic conjugation. Photocurrent generation will be correlated with molecular and bilayer structural changes. Understanding the mechanisms of charge transfer and the relationship between film structure and photocurrent generation will shed light on important current-limiting processes, and help improve the efficiency of photovoltaic devices. The educational initiative includes classes and demonstrations to broaden awareness of alternative energy generation, and outreach activities for a broad audience in Alabama.

奥本大学的Wei Zhan教授得到化学系大分子、超分子和纳米化学（MSN）项目的支持，开发了一类新的分子光伏系统，该系统使用生色团（卟啉）、电子受体（富勒烯）和供体（二茂铁）组装在固体支撑的薄脂质双层膜中。吸附在金上的有机硫醇将用于调节固体载体的表面性质，包括极性、电荷、功函数、氧化还原性质和电子共轭程度。 光电流的产生将与分子和双层结构的变化相关。 了解电荷转移的机制以及薄膜结构与光电流产生之间的关系将有助于阐明重要的限流过程，并有助于提高光伏器件的效率。 教育倡议包括课程和示范，以扩大对替代能源发电的认识，并为亚拉巴马的广大受众开展外联活动。
