Establishing microscopic photophysics in hybrid perovskite solar cells
Background and motivation
The world-increasing demand of clean energy is pushing towards the production of low-cost and efficient solar cells. To overcome silicon-based technology, new materials have emerged such as hybrid perovskites, a mixed organic-inorganic compound. Hybrid perovskites such as MAPbI3 (MA=CH3NH3+) and mixed halide perovskites such as MAPb(I1-xClx)3 and MAPb(I1-xBrx)3 represent intriguing materials since in just 5 years the power conversion efficiencies matched those of silicon. Despite this, there still exists a dearth of microscopic insight into solar cell performance beyond simple device-level metrics. Major issues are:1) to unveil the microscopic photophysics of the material, linking device performance to local electronic disorder originating from cation/anion phase segregation; 2) the long-term stability of hybrid perovskites, that are susceptible to dynamic transformations linked to ion migration, involving both cations and anions.
We are therefore developing spatially-resolved optical techniques that will enable us to study the microscopic photophysics of hybrid perovskite materials. The project we are seeking a student for centers on linking device performance to local electronic disorder originating from cation/anion phase segregation. This will involve direct optical measurements of perovskite thin film as well as solar cell absorption and emission. It will also entail use of a superresolution infrared absorption technique called photothermal heterodyne imaging to directly image for the first time cation migration under applied bias.

Investigating vectorial protein transport through nanopores
Background and motivation
Understanding how proteins fold is the key to addressing neurodegenerative diseases such as Alzheimer’s and Parkinson’s disease. Most of what we know today regarding this problem stems from experiments that use short model proteins that reproducibly fold to a global minimum. This is not representative of how real proteins behave since they are much larger and can begin folding anywhere along their length. Our research thus seeks to overturn conventional wisdom on protein folding by conducting optical studies of single proteins that fold during what is called vectorial transport. This is more representative of how actual proteins fold. The technique we are pursuing involves fluorescence resonance energy transfer (FRET) measurements where individual proteins have been labeled with donor and acceptor molecules. The proteins are then passed through a nanopore followed by single molecule optical microscopy observations of subsequent folding. This work combines single molecule optical microscopy along with modern protein synthesis and functionalization.
