AI Article Synopsis
- Researchers demonstrate that quantum interference can improve coherent electron transmission in perovskite tandem solar cells by using ultrathin layers of indium tin oxide (ITO).
- They create a model utilizing a finite difference time domain approach to solve the time-dependent Schrödinger equation, incorporating an imaginary component to account for losses from incoherent scattering.
- Their findings align with observed efficiency trends based on ITO thickness, indicating a possible optimized design for better solar cell performance.
Article Abstract
We show quantum interference effects can enhance coherent electron transmission in perovskite tandem solar cells using ultrathin indium tin oxide (ITO) layers. We develop a model for the behavior of the power conversion efficiency based on a finite difference time domain solution of the time-dependent Schrödinger equation. The modeled potential includes an imaginary part to simulate probability loss by incoherent scattering. The results agree with observations of efficiency as a function of ITO thickness, suggesting an optimized design.
