Abstract

In this paper, Solar Cell Capacitance Simulator-1D (SCAPS-1D) was used to study the absorber layer defect density and n/i interface of perovskite solar cells versus various cell thickness values. The planar p-i-n structure was defined as PEDOT:PSS/Perovskite/CdS, and its performance was simulated. Power conversion efficiency >25% can be achieved at <1014 cm−3 defect density and >400 nm thickness of absorber layer, respectively. The study assumed 0.6 eV Gaussian defect energy level below the perovskite’s conduction band with a characteristic energy of 0.1 eV. These conditions resulted in an identical outcome on the n/i interface. These results show constraints on numerical simulation for correlation between defect mechanism and performance.

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.
