摘要:
Lateral collection photovoltaic (LCP) structures based on micro- and nano-collecting elements are used to collect photogenerated carriers, wherein the position of the collecting elements is determined by pattern transfer of an alternating depth trench pattern into a material to undergo solid phase crystallization: one depth corresponds to the elements of an electrode and the other depth corresponds to the elements of the counter-electrode. At least one of the metal electrode collecting elements can serve to enhance solid phase crystallization of the surrounding material in which the trenches were formed.

The present invention is directed to thin film transistors using nanowires (or other nanostructures such as nanoribbons, nanotubes and the like) incorporated in and/or disposed proximal to conductive polymer layer(s), and production scalable methods to produce such transistors. In particular, a composite material comprising a conductive polymeric material such as polyaniline (PANI) or polypyrrole (PPY) and one or more nanowires incorporated therein is disclosed. Several nanowire-TFT fabrication methods are also provided which in one exemplary embodiment includes providing a device substrate; deposing a first conductive polymer material layer on the device substrate; defining one or more gate contact regions in the conductive polymer layer; deposing a plurality of nanowires over the conductive polymer layer at a sufficient density of nanowires to achieve an operational current level; deposing a second conductive polymer material layer on the plurality of nanowires; and forming source and drain contact regions in the second conductive polymer material layer to thereby provide electrical connectivity to the plurality of nanowires, whereby the nanowires form a channel having a length between respective ones on the source and drain regions.
