Sea-urchin shaped gamma-MnO2 hierarchical structures have been synthesized using a facile hydrothermal method without employing any template or surfactant with mild conditions. The as-synthesized samples were characteriz...
Controlling the morphology in bulk-heterojunction solar cells is the preferred and most effective way to achieve high efficiency. To control the morphology, we synthesized a novel hydrophobic end-functionalized P3HT to i...
Galvanic wet etching was adopted to fabricate Si nanowire arrays (NWAs) as a near-perfect subwavelength structure (SWS), which is an optically effective gradient-index antireflection (AR) surface and also exhibits super-...
Ethynylene-containing benzo[1,2-b:4,5-b'] dithiophene derivatives 1a-c (BPEBDT, BTEBDT and BHPEBDT) were designed and synthesized. Their physicochemical properties were studied by absorption spectra and electrochemistry....
The edges of pristine graphite were covalently grafted with para-poly(ether-ketone) (pPEK) in a mildly acidic polyphosphoric acid (PPA)/phosphorus pentoxide (P2O5) medium. The resulting pPEK grafted graphite (pPEK-g-grap...
The beta-phase of Zn4Sb3 was rediscovered as a very promising thermoelectric material in the mid-nineties. The material seemed to have it all: a very high thermoelectric figure of merit in the technologically important m...
Extensive research activities in polymer synthesis and device engineering have been devoted to the development of donor-acceptor (D-A) bulk heterojunction solar cells in the last years. In such devices, several photophys...
Field-effect mobility and threshold voltage are modulated by functionalizing gold electrodes with chemisorbed SAMs of aromatic thiols having an increasing number of phenylenes. The contact resistance in poly(3-hexylthiop...
