9322559 Meyer Johns霍普金斯大学约翰霍普金斯大学的Gerald J. Meyer博士和Carlo A. Bigalini，费拉拉，意大利大学，开发光电转换的新技术是由无机，生物无机和有机化学计划和国际计划司的支持。纳米结构的光阳极使用溶胶-凝胶处理和新型的电荷介导的配位络合物将被制备。将对所得电池进行表征，并确定其操作机制。将评估这些系统中发生的限制步骤和不期望的反应，并用于优化其长期性能。 当暴露于光时将转移电荷的过渡金属络合物与高表面积氧化物电极的连接提供了提高光电电池效率的机会。在该项目中，将分别在约翰霍普金斯大学和费拉拉大学开发制备光诱导电荷转移所需的金属氧化物和新型金属化合物的新方法。这两者将结合成新的光电器件，其性能将在约翰霍普金斯进行评估和优化。

9322559 Meyer Johns Hopkins University An international collaboration between Dr. Gerald J. Meyer, Johns Hopkins University and Dr. Carlo A. Bignozzi, University of Ferrara, Italy, to develop new techniques for light-to-electricity conversion is supported by the Inorganic, Bioinorganic, and Organometallic Chemistry Program and the Division of International Programs. Nanostructured photoanodes using sol-gel processing and novel charge mediating coordination complexes will be prepared. The resulting cells will be characterized and their operating mechanism will be determined. The limiting steps and undesirable reactions which occur in these systems will be evaluated and utilized to optimize their long term performance. The attachment of transition metal complexes, which will transfer charge when exposed to light, to high surface area oxide electrodes offers an opportunity to improve the efficiency of photoelectric cells. In this project new methods for preparing the requisite metal-oxides and new types of metal compounds for light induced charge transfer will be developed at Johns Hopkins and Ferrara Universities, respectively. The two will be combined into new photoelectric devices whose properties will be evaluated and optimized at Johns Hopkins.
