Functional and Transparent Coatings
We use an atmospheric pressure plasma discharge to fragment and subsequently polymerize small molecules into highly transparent and functional thin films. We constantly develop new processes for the growth of a wide range of materials, including silica, metal oxides, nitrides, and polymer coatings, onto both organic and inorganic substrates.
Perovskite Solar Cells
The impressive carrier lifetimes and diffusion lengths of perovskites, coupled with their optoelectronic resilience to defects, and amenability to remarkably simple solution-processing set them apart from other active PV layers in the solar field. These properties present a special opportunity for rethinking solar cell architectures allowing for innovations that will result in efficient low-cost cells with improved service lifetimes, essentially solving the mechanical and thermal instability in current monolithic layer perovskite architectures.
Biological Tissues and Treatments
Using methods ranging from thin-film analysis techniques adapted for biological tissues to spectroscopic assays, we characterize the effects of environmental exposures and topical treatments on human skin. These studies yield fundamental insight into the mechanisms and biomechanical behavior of the human body's key protective barrier.
Membranes for Energy Storage
Mechanical reliability of polymer membranes is important for a range of energy applications. Our research investigates relevant thin-film mechanical properties such as tearing energy, adhesion and cohesion energy, stiffness and hardness. In particular, we are interested in studying the thermomechanical effect caused by the operation condition and the role of mechanical constraint imposed by the device hardware on the mechanical properties.
