摘要: Carbon nanotube is one of the promising materials for exploring new concepts in solar energy conversion and photon detection. Here, we report first experimental realization a single core/shell nanowire photovoltaic device (2–4°m) based on carbon amorphous silicon. Specifically, multi-walled (MWNTs) was utilized as metallic core, which n-type intrinsic silicon layers were coated. A Schottky junction formed by sputtering transparent conducting indium-tin-oxide layer to wrap outer shell device. The coaxial showed typical diode ratifying properties with turn-on voltage around 1V rectification ratio ∼104 when biased at ±2V. Under illumination, it gave an open circuit ∼0.26V. Our study has shown simple useful platform gaining insight into charge transport collection properties. Fundamental studies such are important improving efficiency future cells or photo detectors.
