- Abstract
- Within recent years, perovskite solar cells have received much attention. They are highly promising candidates for light harvesting in solid-state photovoltaic devices. The power conversion efficiency (PCE) in photovoltaic devices on a rigid substrate has achieved exceeding 20%. Flexible perovskite solar cells have various applications such as wearable electronic textiles and portable devices. The tubular-shaped nanostructure of TiO2 is very interesting, and 3-dimensional highly ordered arrays of TiO2 nanorods and nanotubes can be easily fabricated by anodization of the Ti substrate in specific electrolytes. In this work, TiO2 arrays were made by the anodization of a thin film Ti foil in 0.1 wt% NH4F and 2 vol% H2O containing ethylene glycol at 50 V. The efficient flexible perovskite solar cells based on a Ti substrate have been fabricated using Graphene coated polydimethylsiloxane(PDMS) as the top electrode. The configuration of flexible perovskite solar cell is Ti/TiO2 arrays/CH3NH3PbI3/PTAA/PEDOT:PSS/Graphene/PDMS. The power conversion efficiency (PCE) reached over 12% under AM 1.5 100 mW cm-2 illumination.
