TÓM TẮT
Perovskite solar cell is one of the most promising candidates for future photovoltaic market because of its high power conversion efficiency (>25%). However, most metal top electrodes are typically fabricated by a vacuum deposition method, which makes the fabrication expensive and unsuitable for commercial applications. In this paper, we present devices in which every layer was prepared using a solution process, with a laminated silver nanoparticle film serving as the top electrode. The silver nanoparticle film was produced by spin-coating the nanoparticle silver ink onto a poly(ethyleneterephthalate) (PET) substrate followed by post-annealing at 150 ◦C for 5 min. Introduction of a thin layer of Poly(3,4-ethylenedioxythiophene) polystyrene sulfonate (PEDOT:PSS)/D-sorbitol, plays an important role in improving the adherence of devices and electrical contact during lamination. Thereby, laminated perovskite solar cells with average power conversion efficiency (PCE) of 10.03% were achieved, almost of 90% of the PCE obtained for conventional devices (11.19%) with evaporated silver contact. The electrical and morphological properties of thermally annealed silver nanoparticle film were also investigated.
