摘要
Part Ⅰ CuS nanosheet films grown on transparent conducting fluorine-doped tin oxide(FTO) substrates were obtained by combining a RF sputtering CuS seeding process with a facile hydrothermal method.The latter XRD patterns of CuS seeds produced by RF sputtering and CuS films obtained by further hydrothermal reaction revealed that the hydrothermal treatment facilitated the transformation from amorphous CuS seeds to crystal CuS nanosheet arrays.Quantum dot-sensitized solar cells(QDSSCs) assembled by employing the CuSseeds and CuS-films as counter electrodes showed superior electrocatalytic compared to Pt CEs.The time effect of RF sputtering was also investigated, indicating that the optimum sputtering time is 30 min.The resulting seed sample marked as CuS-30 min, and the corresponding hydrothermal sample marked as CuS-30 min-hy CEs exhibited enhanced PCE values up to 3.08 % and 3.83 %, which increased 57 % and 95 % as compared to conventional Pt CEs, respectively.Part Ⅱ Fiber-shaped solar cells are a type of photovoltaic device fabricated on one-dimensional conductive substrates, which could be potential candidates for wearable/portable electronics.In this study, we prepared to integrate the inverted structure of Ti(stainless steel)/PEDOT:PSS(NiO)/perovskite/PCBM/Al(Au,CNTs) into the fiber format.The fibershaped inverted perovskite solar cells is expected to reach a considerable PCE under AM 1.5 illumination.All the processes for device fabrication will be easy to handle and energy-saving.The fiber devices exhibited high reproducibility, which could open new doors towards efficient solid fiber shaped photovoltaic cells.
