Hybrid solar cells with vertically aligned CdTe nanorods and a conjugated polymer

Abstract: Vertically aligned CdTe nanorods were fabricated by electrodeposition and were applied for the active layer of solar cells after being combined with poly(3-octylthiophene) (P3OT), a conjugated polymer. The electrodeposited CdTe showed an n-type behavior with the electric resistivity and the electron density of 2×106Ωcm, 1.3×1010cm−3, respectively. Quantum efficiency curve of the hybrid solar cells exhibited a peak at the same wavelength as the optical absorption for CdTe nanorods. The hybrid solar cells demonstrated a power conversion efficiency of 1.06%, whereas the efficiency was only 0.0006% without the nanorods.

A class of narrow-band-gap semiconducting polymers

Abstract: Scientific interest in electrically conducting polymers and conjugated polymers in general has been widespread among workers in polymer science, chemistry, condensed matter physics, materials science and related fields since the discovery of doped conductive poly acetylene1,2 Many doped conducting organic polymers with conductivity spanning the range from insulator to near-metallic ∼10−15–103 ohm−1cm−1) are now known1–13 Of prime importance and fundamental interest in the continuing experimental and theoretical search for new conducting, and perhaps superconducting, polymers is the achievement of small or vanishing values for the semiconductor band gap (Eg), which governs the intrinsic electronic, optical and magnetic properties of materials Existence of a finite Eg in conjugated polymers is thought to originate principally from bond-length alternation, which is related to the Peierls instability theorem for one-dimensional metals114–17 Here I describe a novel class of conjugated polymers, containing alternating aromatic and quinonoid segments, whose members exhibit intrinsic band gaps as low as 075 eV, the smallest known value of Eg for an organic polymer

Preparation of highly conductive polymer nanocomposites by low temperature sintering of silver nanoparticles

Abstract: Highly conductive polymer nanocomposites with very low resistivity (4.8 × 10−5 Ω cm) were prepared by thermal sintering of silver nanoparticles with silver flakes dispersed in a polymer matrix at 180 °C. By comparative studies of thermal behavior of Ag nanoparticles, the critical processing temperature required to obtain very low resistivity of polymer nanocomposites has been identified for Ag nanoparticles with different surface properties. The results indicate that the decomposition temperature of surface residues on Ag nanoparticles plays a key role in the sintering of Ag nanoparticles and thus the electrical resistivity of the polymer nanocomposites. Electrical measurements of the polymer nanocomposites showed that morphological changes induced by sintering of Ag nanoparticle with Ag flakes considerably contribute to the reduction of the contact resistance between conductive fillers, increasing the nanocomposite conductivity.
