3D Printed Top Electrode for Highly Efficient and Transparent Four-Terminal Tandem Solar Cell |
| 초록 |
An efficient solar power technology is necessary to cope up with the constantly increasing energy requirements. The four-terminal perovskite/silicon tandem solar cell has already achieved a record efficiency 28.3%. In a four-terminal tandem configuration, the top transparent electrode of perovskite solar cell (PSC) must possess high transparency and low sheet resistance (RSHEET). Here, we present a hybrid transparent conducting electrode (TCE) composed of 3D-printed metal grids embossed over a transparent conducting oxide film (TCO) for an inverted type of semi-transparent PSC. The hybrid electrode had an average transmittance of ~84% (@800-1000 nm). A ST-PSC having active area of ~1 cm2 and an AVT of ~73% (@800-1000 nm), rendered a PCE of ~17%. The ST-PSC was applied to a 4-T configuration with a commercial silicon solar cell having a PCE of 17.62%. The tandem cell rendered a total PCE of 23.5%. |
