A transparent pn junction comprising CuI/LaCoO3 QDs/SrTiO3 was synthesized using the solgel-hydrothermal-freeze drying-sputtering in situ iodization method. The achieves transmittance of ∼85%, photoelectric enhancement ∼2.2 × 103-fold to intrinsic CuI/SrTiO3, and good stability 5 months. It can be primarily attributed LaCoO3 QDs. In addition appropriate Fermi level high QY, QDs with carrier inducing–injecting–driving ameliorate dynamics for PCE-transparency balance, meanwhile increasing hole by Cu vacancy. Furthermore, CuI, LaCoO3, SrTiO3 maintain structural potential devices.

Nickel hydroxide has ultra-high energy storage capacity in supercapacitors, but poor electrical conductivity limits their further application. The use of graphene to improve its is an effective measure, how suppress the stacking and overall performance composite materials become a new challenge. In this work, well-designed substrate N-doped carbon nanowires with reduced oxide (NCNWs/rGO) was fabricated by growing polypyrrole (PPy) between GO nanosheets layers then calcining them at high temperatures. This NCNWs/rGO can effectively avoid rGO nanosheets, provides sufficient sites for subsequent situ growth Ni(OH)2, forming uniform stable Ni(OH)2/NCNWs/rGO material. Benefiting from abundant pores, specific surface area (107.2 m2 g-1), conductive network throughout substrate, deposited Ni(OH)2 not only realize loading ratio, also exposes more active surfaces (221.3 g-1). After comprehensive electrochemical test, it found that positive have capacitance 2016.6 F g-1 scan rate 1 mV s-1, exhibit significantly better stability. assembled Ni(OH)2/NCNWs/rGO//AC asymmetric supercapacitor could achieve density 85.2 Wh kg-1 power densities 381 W kg-1. addition, excellent stability retain 70.1% initial after 10,000 cycles. These results demonstrate feasibility using construct high-performance electrode materials, expected be promoted other materials.
