Abstract:
The present invention relates to a construction material comprising a solar cell. The construction material of the present invention has an opening and an edge frame. The opening is blocked by a light receiving portion including a light guide portion for guiding light radiated to the opening toward the frame side. The construction material includes a solar cell arranged at the light exit of the light guide portion. The construction material applied to the outer walls of buildings or specifically to doors and windows collects light and supplies the collected light to the solar cell in a vertical direction even under a non-direct solar radiation condition, to thereby improve solar cell generation efficiency, and operate in an efficient manner even under a non-direct solar radiation construction condition. The construction material applied to doors and windows provides semitransparent windows, allows for an unobstructed view, and collects light to enable a high efficiency of the solar cell, thereby satisfying both of the effects of generating power and ensuring an unobstructed view.
Abstract:
The present invention relates to a dye-sensitized solar cell module, and more specifically, to a dye-sensitized solar cell module in which neighbouring cells or sub-modules are electrically connected by having an anodic electrode overlap a neighbouring cathodic electrode. The dye-sensitized solar cell module is characterized in that at least one surface of an overlap portion has a lead line having curved parts or projecting parts which start from one end of the anode or cathode and are curved in the middle. The formation of curved parts or projecting parts in the lead line of the overlap portion between the cells or the sub-modules in the dye-sensitized solar cell results in extending the length of the lead line and increasing the edge density, thereby enlarging a conduction pathway along the edge and leading the current to flow better and evenly along the edge. As a result, the series resistance of the dye-sensitized solar cell module is reduced, and the photoelectric conversion efficiency of the solar cell module is improved.

Disclosed are a vanadia-titania aerogel catalyst having high specific surface area and porosity, a method of preparing the same and a method of completely oxidatively-decomposing a chlorinated aromatic compound using the catalyst under air condition. The vanadia-titania aerogel catalyst of the invention is an aerogel form having many porosities and a high specific surface area obtained by performing a supercritical drying of vanadia-titania wet gel, which is prepared by a sol-gel method, with carbon dioxide and then firing the dried vanadia-titania, with a micro porosity structure being maintained, consists of vanadia and titania wherein a content of the vanadia is 1~15 wt % of an overall catalyst weight. In addition, according to the invention, the vanadia-titania aerogel catalyst may further comprise a manganese oxide of 1-5 wt% or a sulfur component of 0.0001-1 wt%. Since the vanadia-titania aerogle catalyst of the invention has the very high conversion rate and selectivity for the complete oxidation reaction of the chlorinated aromatic compound and is very thermally stable, it can be usefully used in the oxidation reaction having a high heating value capable of generating local heat spots.

The present invention relates to a method of patterning a transparent conductive oxide film of conductive glass, and a conductive glass prepared thereby. Specifically, the present invention relates to a method of patterning a transparent conductive oxide film of a conductive glass comprising the steps of: forming a photoresist pattern on the part of the surface of a glass substrate where a transparent conductive oxide film is not to be formed; forming a transparent conductive film on the glass substrate; and removing the photoresist from the glass substrate, and a conductive glass prepared thereby. According to the present invention, a transparent conductive oxide (TCO) film can be patterned more easily and more inexpensively. Particularly, in the case of using TCO consisting of FTO, a conductive glass comprising FTO pattern formed thereon can be manufactured without using expensive laser equipment, and such conductive glass can be used as an electrode plate of a dye-sensitized solar cell.
Abstract:
A method for preparing carbon aerogels and carbon aerogels obtained therefrom are disclosed. The method for preparing carbon aerogels comprises: mixing organic starting materials including phloroglucinol and furfural with a solvent capable of dissolving the organic materials in a predetermined ratio to form a sol solution; adjusting pH of the sol solution adequately by using an acidic or basic catalyst, gelling the sol solution at room temperature under atmospheric pressure, and aging the resultant gels; substituting the solvent in thus obtained gels with liquid carbon dioxide, followed by drying in a supercritical state, to form organic aerogels; and pyrolyzing the organic aerogels in an electric furnace under inert atmosphere to obtain carbon aerogels. Particularly, the gels are formed at room temperature in a short period of time by adequately adjusting pH of the sol solution. Therefore, the method provides improved time efficiency and energy efficiency as compared to existing methods for preparing gels. Additionally, the method allows supercritical drying while avoiding a need for an additional solvent substitution, thereby simplifying the overall process. Further, the method enables preparation of carbon aerogels for supercapacitors having a high specific surface area and high capacitance even in the absence of additional activation step.
