摘要
Part Ⅰ Here, we report an ultrathin titanium foil that integrates a perovskite solar cell and electro-chemical supercapacitor, unlike the approach of using two independent components.When the self-powered integrated energy device was illuminated with simulated solar light, the power pack can be charged to about 0.64 V within thirty seconds, and the stored energy was supplied for 75 seconds at a current density of 0.5 mA cm~(-2).The total value of photoelectric conversion and storage efficiencies for this system can be reached to 5.1 %.Part Ⅱ We present a highly transparent conducting CuS-nanosheet(NS) networks with an optimized sheet resistance(Rs) as low as 50 ? sq~(-1) at 85% transmittance as counter electrode(CE) for flexible quantum-dot solar cell(QDSC).CuS NS network electrode exhibits remarkable mechanical flexibility under bending tests compared to traditional ITO/plastic substrates and sputtered CuS film.Herein, CuS NS networks not only served as conducting films for collecting electrons from the external circuit, but also as superior catalysts for reducing polysulfide(S~(2-)/S_x~(2-)) electrolytes.A power conversion efficiency(PCE) up to 3.25% was achieved for the QDSCs employing CuS NS networks as CEs, which was much higher than those of the devices based on Pt networks and sputtered CuS film.We believe such CuS network TCEs with high flexible, transparent, conducting and catalytic activity could be widely used in wearable electronic products.
