Wet chemical processes have always played a part in the manufacture of lab-based photovoltaic (PV) cells, from surface etching and texturing through to chemical deposition of various device components and layers. In spite of vacuum-based deposition techniques still dominating many aspects of cell processing, there is growing interest in solution-based depositions and treatments of device components, due to the necessary benign conditions and potential for lower manufacturing costs. This has been exemplified in the recent explosion of interest in thin film lead halide-based perovskite solar cells, where very high quality devices have been processed from simple solution spin-coating techniques. This seminar will present aspects of wet-chemical processing of PV cells, discussing approaches and research carried out at the Institute of Energy Conversion and elsewhere, and consider its possible roles in the development of high quality, low cost solar devices.


Dr. Dobson is an Associate Scientist at the Institute of Energy Conversion at the University of Delaware. He received his Ph.D. in Chemistry from the University of Otago, New Zealand, investigating adsorption to metal oxides from aqueous solution using infrared spectroscopic techniques. Following this he accepted a Post-Doctoral Fellowship at the Weizmann Institute of Science, Israel, investigating contacting and stability aspects of CdTe/CdS solar cells. Dr. Dobson joined the Institute of Energy Conversion in 2001 where he has studied performance and stability of CdTe/CdS solar cells, processing of Cu(In,Ga)Se 2 -related materials for PV application, and chemical treatments for solar device manufacture.
