Zusammenfassung:Paper is an ideal substrate for the development of flexible and environmentally sustainable ubiquitous electronic systems. When combined with nanomaterials, it can be harnessed for various Internet-of-Things applications, ranging from wearable electronics to smart packaging. In this study, we present a non-vacuum spray deposition of arrays of hybrid single layer graphene (SLG)-CsPbBr3 perovskite quantum dots (QDs) photodetectors on a paper substrate. This approach combines the advantages of two large-area techniques: chemical vapor deposition (CVD) and spray-coating. The first technique allows for the pre-deposition of CVD SLG, while the second enables the spray coating of a mask to pattern CVD SLG, electrode contacts, and photoactive QDs layers. The prepared paper-based photodetectors achieved an external responsivity of 520 A/W under 405 nm illumination at
