dc.description.abstractThe production of uniform layers without defects is crucial for the efficient upscaling of perovskite solar cells. To understand the origin of defects and their impact on efficiency, we compare steady-state (DC) and alternating current (AC) measurements with simulation results obtained by an electro-thermal 2D+1D finite element method (FEM) implemented in the software Laoss. The software supports the upscaling process from small- to large-area devices by solving for the potential and temperature distribution in 2D top and bottom electrode domains, which are coupled by a vertical 1D coupling law. Recently, we extended this FEM model to the frequency domain in order to study both DC and AC characteristics of solar cells. Here, we report on the extension of this frequency-dependent FEM model to the thermal domain, allowing us to calculate amplitude and phase images of solar cells that are voltagemodulated in the dark. We measured and modelled a screen-printed carbon-based hole-transporter-free perovskite solar cell with a defect, appearing as a hotspot in temperature measurements. In contrast to the traditional DLIT method using a large voltage modulation, we introduce a small-signal DLIT (SS-DLIT) imaging method which our model is capable to reproduce. Fitting thermal AC simulations to measured data, allowed to quantify the defect and examine its behaviour and origin.de_CH
