Embodiment 1

[0165] array of optoelectronic devices

[0166] Build what is described in this paper as follows and according to Figure 10 with Figure 11 An array of optoelectronic devices is illustrated. with SiO 2 or TiO 2 Planarization and adhesion layers to coat arrays of plastic optical fibers. For example, at 1000rpm SiO 2 layer, spin-coated on SiO 2 Sol on the plastic optical fiber array. Form SiO by stirring and aging a mixture of tetraethylorthosilicate (TEOS), ethanol, hydrochloric acid, and water 2 Sol. In allowing the deposition of SiO 2 After the layer dried overnight, ITO was sputter-deposited on the coated SiO 2on the fiber array. A photosensitive layer of a-Si:H is then deposited on the ITO layer using reactive radio frequency plasma-enhanced chemical vapor deposition (RF PECVD) from a Si source. The a-Si:H photosensitive layer is deposited in p-i-n order. First, a 100 nm thick layer of p-doped a-Si:H is deposited. Next, a 200 nm layer of intrinsic a-Si:H is d...

Abstract

In one aspect, optoelectronic devices are described herein. In some embodiments, an optoelectronic device comprises a fiber core, a radiation transmissive first electrode surrounding the fiber core, at least one photosensitive inorganic layer surrounding the first electrode and electrically connected to the first electrode, and a second electrode surrounding the inorganic layer and electrically connected to the inorganic layer. In some embodiments, the device comprises a photovoltaic cell.

Description

[0001] References to related applications [0002] Pursuant to 35 U.S.C. §119(e), this application claims U.S. Provisional Patent Application Serial No. 61 / 394,319, filed October 18, 2010, and U.S. Provisional Patent Application Serial No. 61 / Priority No. 525,335, the entire contents of which are hereby incorporated by reference. technical field [0003] The present invention relates to optoelectronic devices (photovoltaic devices) and, in particular, to inorganic fiber optoelectronic devices (photovoltaic devices). Background technique [0004] Optoelectronic devices convert electromagnetic radiation into electricity by generating a photogenerated current when connected across a load and exposed to light. Electricity generated by photovoltaic cells (photovoltaic cells) can be used in many applications, including lighting, heating, battery charging, and powering devices requiring electrical energy. [0005] When irradiated with an infinite load, a photovoltaic device prod...
