Simple Synthesis of Flower-Like ln2S3 Structures and Their Use as Templates to Prepare CuS Particles

Flower-like structure In2S3 particles are prepared by a simple and rapid method. The reaction proceeds in a polyalcohol system without using any complex precursors. The phase and morphology of the In2S3 are investigated. Furthermore, flower-like structure CuS particles are synthesized via the reaction of Cu2+ ions with the obtained In2S3 as templates. Both the In2S3 and CuS particles can be used in preparing compound solar cell material CuInS2

CdSe Quantum Dots Sensitized Mesoporous TiO2 Solar Cells with CuSCN as Solid-State Electrolyte

Mesoporous TiO2 is functionalized by 3-mercaptopropyl trimethyoxysilane (MPTMS) to anchor CdSe quantum dots (QDs). The resulting TiO2/CdSe is combined with solid-state electrolyte (CuSCN) to form solar cells. It is found that the efficiency of electron injection from QDs to TiO2 can be improved owing to the substitution of the long chains of organic capping agents at the surface of QDs with MPTMS. The hydrolyzate of MPTMS forms an insulating barrier layer to reduce the recombination at the TiO2/CdSe interface, leading to the increase of open-circuit voltage (Voc)

Growth of In₂O₃ Nanowires Catalyzed by Cu via a Solid–Liquid–Solid Mechanism

<p>Abstract</p> <p>In₂O₃ nanowires that are 10&#8211;50 nm in diameter and several hundred nanometers to micrometers in length have been synthesized by simply annealing Cu&#8211;In compound at a relatively low temperature of 550&#176;C. The catalysis of Cu on the growth of In₂O₃ nanowires is investigated. It is believed that the growth of In₂O₃ nanowires is via a solid&#8211;liquid&#8211;solid (SLS) mechanism. Moreover, photoluminescence (PL) peaks of In₂O₃ nanowires at 412 and 523 nm were observed at room temperature, and their mechanism is also discussed.</p
