Problems description

Perovskite-based solar cells convert sunlight to electricity more efficiently than classical silicon solar cells. The current sunlight conversion efficiency is 34.6%. The efficiency is particularly high in nanotextured perovskite solar cells. However, why these cells have better electronic properties has largely remained a mystery.

Goals

Correctly model and simulate multi-dimensional charge carrier dynamics as well as optical effects to understand the improved electronic performance of perovskite solar cells.

Methods

Modelling, Drift-diffusion, Finite volume simulationss, Numerical analysis, Time-harmonic Maxwell’s equation

Outcome

A physical explanation of the device performance (reduced detrimental recombination); Open-source simulation tool implemented in ChargeTransport.jl
