While Silicon photovoltaic (PV) cells have been the workhorse of solar power generation, many different PV technologies will need to be employed to achieve a greener energy future. One promising emerging technology is Perovskite solar cells, which have demonstrated >25% power conversion efficiency (PCE) with only a decade of research. It has been found that this material also has desirable properties for another emerging technology: All-Back-Contact (ABC) thin-film PV devices. This work investigates Perovskite absorbers in two different ABC designs: Quasi-Interdigitated Back Contact (QIBC) and Metasurface Lattice Back Contact (MSLBC) consisting of a periodic array of photo-absorbing cylinders. Due to the similarity to MSLBC designs, a Metasurface Perfect Absorber (MSPA) was also investigated. The optoelectronic performance of these devices was simulated using COMSOL Multiphysics®, which uses the finite element method to solve sets partial differential equations. It was found that a textured front surface for the QIBC device provides superior optical absorption over a flat front surface at higher wavelengths due to light trapping and optical resonance. Despite the inferior optical performance, the flat front surface QIBC design was shown to achieve a PCE >23%. The MSPA design was found to have high absorption for a wide range of incident angles due to Mie resonance within the periodic cylindrical structures. Strong absorption was also observed in the MSLBC device due again to Mie resonance. The PCE of this device was found to be superior under bottom illumination with room for improvement. Optimization of this design was performed by targeting the cylinder diameter and cylinder height. By comparing the optical and electronic performance for a wide range of these parameters, optimal values were found. The bifacial performance of this device was then examined and it showed little improvement over single-side illumination.
