Comment on "Resolving spatial and energetic distributions of trap states in metal halide perovskite solar cells"
Sandheep Ravishankar, Thomas Unold, Thomas Kirchartz
Ni et al. report minimum bulk trap densities of 10^11 cm-3 and 1-4 orders change in interfacial trap densities derived from drive-level capacitance profiling of lead halide perovsk…
Pitfalls and prospects of optical spectroscopy to characterize perovskite-transport layer interfaces
Eline M. Hutter, Thomas Kirchartz, Bruno Ehrler +2
Perovskite photovoltaics has witnessed an unprecedented increase in power conversion efficiency over the last decade. The choice of transport layers, through which photo-generated…
A highly integrated, stand-alone photoelectrochemical device for large-scale solar hydrogen production
Minoh Lee, Bugra Turan, Jan-Philipp Becker +9
Although photoelectrochemical water splitting is likely to be an important and powerful tool to provide environmentally friendly hydrogen, most developments in this field have been…
Requirements for functional pn-homojunctions in lead-halide perovskite solar cells
Thomas Kirchartz, David Cahen
Cui et al. describe the fabrication and characterization of planar pn-junction solar cells based on lead-halide perovskites. The doping densities measured using Hall effect measure…
Solar Energy Conversion and the Shockley-Queisser Model, a Guide for the Perplexed
Jean-Francois Guillemoles, Thomas Kirchartz, David Cahen +1
The Shockley-Queisser model is a landmark in photovoltaic device analysis by defining an ideal situation as reference for actual solar cells. However, the model and its implication…
High Open-Circuit Voltages in Lead-Halide Perovskite Solar Cells - Experiment, Theory and Open Questions
Thomas Kirchartz
One of the most significant features of lead-halide perovskites are their ability to have comparably slow recombination despite the fact that these materials are mostly processed f…
