Our increasing energy requirements have made it necessary for us to develop more highly efficient solar power technology. The perovskite-silicon tandem solar cell structures are one of the most promising approaches to achieve higher efficiency and already achieved a certified efficiency 29.5%. Here, we present a highly transparent top-electrode consisting of 3D-printed multi-layered metal grids embossed over a transparent conducting oxide film (TCO) for semitransparent-perovskite solar cell (ST-PSC) based on a triple-cation perovskite absorber with a bandgap of 1.6 eV. After 3D printing of metal grid, the sheet resistance of TCO dropped from ~45 Ω/□ to ＜1 Ω/□. The ST-PSC having an active area of 1 cm2 and an AVT of 73.1% (@800-1000 nm), rendered a remarkable PCE of 16.99%. Moreover, when applied to a 4-T configuration with a commercially available silicon solar cell having a PCE of 17.62%, the tandem cell achieved a total PCE of 23.50%. |
