High performance of large-sized dye sensitized solar cells based on a novel low-cost metal grids manufactured process

In this study, a novel low-cost fabrication process of Al-based metal gr ids for large-sized dye sensitized solar cells (DSSCs) was developed. The Al-based metal grids layer is introduced by sputtering deposition on FTO glass to collect current and reduce the R
_TCO
of large area DSSCs. With the Al-based metal gr ids technology, we achieved 4.8% conversion efficiency in the active area of 12.8cm
²
, an improvement by 120% in contrast with the counterpart without using the Al-based metal grids technology.
