Organic-inorganic hybrid materials promise both the superior carrier mobility of inorganic semiconductors and the processability of organic materials. A thin-film field-effect transistor having an organic-inorganic hybrid material as the semiconducting channel was demonstrated. Hybrids based on the perovskite structure crystallize from solution to form oriented molecular-scale composites of alternating organic and inorganic sheets. Spin-coated thin films of the semiconducting perovskite (C(6)H(5)C(2)H(4)NH(3))(2)SnI(4) form the conducting channel, with field-effect mobilities of 0.6 square centimeters per volt-second and current modulation greater than 10(4). Molecular engineering of the organic and inorganic components of the hybrids is expected to further improve device performance for low-cost thin-film transistors.

    • "The halide perovskite (CH 3 NH 3 PbX 3 , X = Cl, Br and I) solar cells (PSCs) have attracted considerable attention due to their great advantages, for example, direct band gap, large absorption coefficient , high carrier mobility [1] [2] [3] [4]. These merits accelerate the rapid development of PSC devices with the power conversion efficiencies (PCEs) increasing from 3.8% to over 20% [5] [6] [7] [8] [9] [10] [11]. "

    • "In order to meet the above challenges, many research groups are working towards the development of a low cost solid state methyl ammonium lead iodide (CH 3 NH 3 PbI 3 ) perovskite based solar cells [6] [7] [8] [9] [10] [11] [12] [13] [14] [15]. Presently, these solar cells have reached a conversion efficiency of 16% [16] and establishing itself as a cheap alternative to conventional silicon solar cells due to its tunable band gap, high absorption coefficient, high carrier mobility and good stability [17] [18] [19].

    ABSTRACT: A solid-state mesoporous titanium dioxide (mTiO2) layer based hetero-junction solar cell, employing nanoparticles (NPs) of methyl ammonium lead iodide perovskite (CH3NH3PbI3) as light harvesters has been studied. The optimum performance parameters of CH3NH3PbI3 are observed as a function of sintering temperature and confirmed by X-ray diffraction analysis and UV-Vis spectrophotometry. A solid-state solar cell with the sandwich structure of mTiO2/CH3NH3PbI3/Graphite paste showed a power conversion efficiency of 1.11% tested under standard Air Mass 1.5 Global (1000 Wm-2, AM1.5G) solar spectrum. Two-diode model is used to explore the performance limiting factors of the developed solid-state perovskite solar cell.

    ABSTRACT: A new magnesium sulfate templated by 2-methylpiperazine, (C5H14N2)[Mg(H2O)6](SO4)2, was prepared by the slow evaporation method. The obtained crystals were investigated by the Raman and FTIR spectroscopy and crystallographically characterised by single-crystal X-ray diffraction. The compound crystallises in the monoclinic system, space group P21/n. Supramolecular network of this hybrid material consists of Mg2+ cations octahedrally coordinated by six water molecules, sulfate tetrahedra and protonated and disordered diamine linked together by two types of hydrogen bonds: OW—H…O and N—H…O. Dehydration of the title compound takes place in three steps. Thermal decomposition of the anhydrous phase consists in the loss of the organic moiety and one sulfate group leading to the formation of magnesium sulfate.
