発明の名称 (英語) OPTICAL WAVEGUIDE DEVICE, PHOTOELECTRIC CONVERSION DEVICE, ARCHITECTURAL STRUCTURE, ELECTRONIC APPARATUS AND LIGHT-EMITTING DEVICE
発明の概要(英語) An optical waveguide device comprises a planar optical waveguide 10, a transparent layer 20 located on a principal surface thereof and having refractive index anisotropy, and a reflecting mirror array 30 located thereon. Reflecting mirrors 31 of the reflecting mirror array 30 reflect three-dimensional space propagation light entering from outside and causes the reflected three-dimensional space propagation light to enter the layer 20 having refractive index anisotropy. The layer 20 having refractive index anisotropy permits transmission of light that enters the layer 20 having refractive index anisotropy by the reflection of the three-dimensional space propagation light by the reflecting mirrors 31, and restricts transmission of light that enters the layer 20 having refractive index anisotropy after entering the planar optical waveguide 10 through the layer 20 having refractive index anisotropy and then being fully reflected by the back surface of the planar optical waveguide 10. A photoelectric conversion device is configured by providing a semiconductor layer for photoelectric conversion at an end of the planar optical waveguide 10.
従来技術、競合技術の概要(英語) BACKGROUND ART
Cyclic society as a key technology of the future, also simply referred to as well as to prevent the global warming potential, consistent with the natural environment and green for subsequent generations of the earth to the parking attendant human, more effective use of the sunlight is desired. The world from this point of view by the solar battery is attracting attention, the photoelectric conversion efficiency is improved and manufacturing cost can be reduced so as to reduce the research and development has been actively performed.
Before the present inventor, the dead zone for the incident light can be eliminated, staebler, the ski and the conduction (Staebler Wronski) effect and ultraviolet components can be suppressed and the degradation of the organic semiconductor, it is possible to obtain a high photoelectric conversion efficiency, a large area is also very simple, suitable for use as a solar cell of a photoelectric conversion device is proposed (see Patent Document 1.). And the photoelectric conversion device, 3 - dimensional space propagation light can be converted into propagation light 2 and the three-dimensional space structure, 2 the three-dimensional space of the planar waveguide propagating light and the optical waveguide, the planar light waveguide is provided at the end of the photoelectric conversion semiconductor layer and the, the planar light waveguide of the light incident on the main surface of the planar optical waveguide is guided in the light incident on the semiconductor layer is configured, the planar light waveguide of the light being wave guided within the traveling direction of the net, the planar optical waveguide from the end face of the light incident on the semiconductor layer on the semiconductor layer by the carriers generated in the direction of movement of the net angle and substantially at right angles. 3 2 Three-dimensional space propagation light can be converted to propagating light three-dimensional space as a structure, the main surface of the planar optical waveguide or planar optical waveguide provided in the diffraction grating is used. The most effective as a diffraction grating having a structure as described below have been proposed (Patent Document 1 described in paragraph 0073, see Fig. 23 and Fig. 24.). That is, the main surface of the planar optical waveguide (light incident surface) of rectangular cross section in a part of the comb-teeth-shaped convex portion is periodically formed in a concavo-convex structure is formed periodically, this periodic concavo-convex structure is a diffraction grating. The main surface of the planar optical waveguide to the opposite surface (back surface), the relief structure periodically over the area larger than that of aluminum (Al) functions as a reflective film formed on the back metal. And the back metal at the interface of the planar optical waveguide and a saw-tooth shape, in the saw-like interface of a small back metal the light impinging on the inclined surface which is reflected in various directions respectively. Using this model the surface of the optical waveguide is to verify the performance of the waveguide according to the result of simulation carried out, the relief structure periodically in a direction perpendicular to the incident light, many of which are diffracted by the periodic concavo-convex structure on the altered 90° the traveling direction of the optical waveguide is guided in a planar shape. That is, the direction of the optical waveguide propagating light wave guide can be said that the redirection (redirection waveguide) (3 incident light in the three-dimensional space and to 2 after the three-dimensional space propagating light, guided in a transverse direction immediately in order to cause the functional thin film structure) was shown to be feasible. With respect to light of other wavelengths, by appropriately changing the dimension of the protruding part and the period corresponding to possible.
