The spatial collection efficiency of photogenerated charge carriers in photovoltaic and photoelectrochemical devices
Gideon Segev, Hen Dotan, David S. Ellis +7
The spatial collection efficiency portrays the driving forces and loss mechanisms in photovoltaic and photoelectrochemical devices. It is defined as the fraction of photogenerated…
Van der Waals Materials for Atomically-Thin Photovoltaics: Promise and Outlook
Deep Jariwala, Artur R. Davoyan, Joeson Wong +1
Two-dimensional (2D) semiconductors provide a unique opportunity for optoelectronics due to their layered atomic structure, electronic and optical properties. To date, a majority o…
High Photovoltaic Quantum Efficiency in Ultrathin van der Waals Heterostructures
Joeson Wong, Deep Jariwala, Giulia Tagliabue +4
We report experimental measurements for ultrathin (< 15 nm) van der Waals heterostructures exhibiting external quantum efficiencies exceeding 50%, and show that these structures ca…
Grand canonical electronic density-functional theory: algorithms and applications to electrochemistry
Ravishankar Sundararaman, William A. Goddard, Tomas A. Arias
First-principles calculations combining density-functional theory and continuum solvation models enable realistic theoretical modeling and design of electrochemical systems. When a…
Experimental and ab initio ultrafast carrier dynamics in plasmonic nanoparticles
Ana M. Brown, Ravishankar Sundararaman, Prineha Narang +3
Ultrafast pump-probe measurements of plasmonic nanostructures probe the non-equilibrium behavior of excited carriers, which involves several competing effects obscured in typical e…
Pattern Decomposition with Complex Combinatorial Constraints: Application to Materials Discovery
Stefano Ermon, Ronan Le Bras, Santosh K. Suram +4
Identifying important components or factors in large amounts of noisy data is a key problem in machine learning and data mining. Motivated by a pattern decomposition problem in mat…
