Abstract
- A planar perovskite solar cell that incorporates a nanocarbon hole-extraction layer is demonstrated for the first time by an inkjet printing technique with a precisely controlled pattern and interface. By designing the carbon plus CH<subscript>3</subscript>NH<subscript>3</subscript>I ink to transform PbI<subscript>2</subscript> in situ to CH<subscript>3</subscript>NH<subscript>3</subscript>PbI<subscript>3</subscript>, an interpenetrating seamless interface between the CH<subscript>3</subscript>NH<subscript>3</subscript>PbI<subscript>3</subscript> active layer and the carbon hole-extraction electrode was instantly constructed, with a markedly reduced charge recombination compared to that with the carbon ink alone. As a result, a considerably higher power conversion efficiency up to 11.60 % was delivered by the corresponding solar cell. This method provides a major step towards the fabrication of low-cost, large-scale, metal-electrode-free but still highly efficient perovskite solar cells. [ABSTRACT FROM AUTHOR]
