Solar Energy to Fuels, Chemicals and Electricity
ChE-605 - Highlights in Energy Research seminar series
Ecole polytechnique fédérale de Lausanne
In the long run, it is likely that all the basic human needs will be met by renewable sources like solar energy. However, there are several challenges associated with the harness, storage and use of solar energy to meet our daily needs for food, chemicals, heat, electricity and transportation. The research in our group is focused on addressing some of these challenges and we will present our results in a two-part presentation.
In the first part of the presentation, we will discuss results from our energy systems modeling for liquid fuel production. An exciting aspect of producing fuels and chemicals from biomass is learning to produce the array of molecules that we need with minimum process transformation steps and energy use while maximizing biomass carbon recovery. In this respect, recent advancements at Purdue by a team of chemists, biologists and chemical engineers will be presented. We will show the new pathways and the associated catalysts that have been developed for the production of fuel and chemicals from biomass.
In the second part of the presentation, we will discuss our research related to solution-processed thin-film inorganic solar cells. We will present process and technical solutions leading to power conversion efficiencies that are among the highest for Cu(In,Ga)Se2 and Cu2ZnSnSe4 based solar cells by solution based routes. We will also discuss the exciting new chemistry using amine/thiol mixtures for molecular precursor inks and fabrication of solar cells from them. The excitement of solution route’s science and technology along with its challenges will be presented.
