| Abstract Scope |
Functional nanomaterials and composites based on graphene and metal oxides has led to significant advances in the development of perovskite solar cells (PSCs) and multicomponent detecting sensors. We developed simple methods for production of functional nanocomposites such as Ag-graphene, perovskite/Ag-graphene, NiO-carbon-graphite, Al2O3/graphene, perovskite-NiO, perovskite/Sn-graphene, etc and utilized them for the fabrication of highly stable and efficient PSCs. The composites-based PSCs showed an efficiency over 20 % and remarkable stability with retaining 97-99 % of the initial values of photovoltaic parameters with sustaining ~ 93% of initial efficiency over 300 days under ambient conditions. We also developed graphene and metal oxides based functrional nanomaterials for detecting multiple analytes with field-effect transistors (FETs) array chemcial and biological sensors. The development of an integrated FETs array biosensor platform will have a significant impact on rapid detection under critical patient conditions, early identification of disease/disorder and on future generations. |
