	abstract = {<p>Combined perovskite/crystalline-silicon four-terminal tandem solar cells promise \&gt;30\% efficiencies. Here we propose all-thin-film double-junction architectures where high-bandgap perovskite top cells are coupled to ultrathin c-Si bottom cells enhanced with light trapping. A complete optoelectronic model of the devices was developed and applied to determine the optimal intermediate layers, which are paramount to maximize the cells{\textquoteright} photocurrent. It was ascertained that by replacing the transparent conductive oxides by grid-based metallic contacts in the intermediate positions, the parasitic absorption is lowered by 30\%. Overall, a 29.2\% efficiency is determined for \~{}2 um thick tandems composed of the optimized interlayers and improved with Lambertian light trapping.</p>
