Optical Transitions in Hybrid Perovskite Solar Cells: Ellipsometry, Density Functional Theory, and Quantum Efficiency Analyses forCH3NH3PbI3
Open accessAbstract
Measuring ultrasmooth layers of the important photovoltaic absorber CH${}_{3}$NH${}_{3}$PbI${}_{3}$, the authors find that earlier studies have seriously overestimated its absorption coefficients. Their calculations show that free-carrier generation occurs via nonexcitonic, semiconductor-type interband transitions within the PbI${}_{3}$ subunit. Using their revised optical constants, the quantum efficiency spectrum of a standard hybrid perovskite solar cell is reproduced very realistically. The wealth of information from this study enables depth-resolved optical simulations for the design of tomorrow's CH${}_{3}$NH${}_{3}$PbI${}_{3}$ solar cells.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
