摘要:
A thin film solar cell includes a substrate, a first electrode positioned on the substrate, a second electrode separated from the first electrode, and a photoelectric conversion unit positioned between the first electrode and the second electrode. The photoelectric conversion unit includes a p-type semiconductor layer, an intrinsic semiconductor layer, and an n-type semiconductor layer. The p-type semiconductor layer includes a first doped layer, a second doped layer, and a third doped layer. A carbon content of the second doped layer positioned between the first doped layer and the third doped layer is more than a carbon content of the first doped layer and a carbon content of the third doped layer.

A thin film solar cell and a method for manufacturing the same are discussed. The thin film solar cell includes a plurality of cells positioned on a substrate. Each of the plurality of cells includes a first electrode positioned on one surface of the substrate, at least one photoelectric conversion unit positioned on the first electrode, a back reflection layer including a first reflection layer contacting the at least one photoelectric conversion unit and a second reflection layer having an opening exposing a portion of the first reflection layer, and a second electrode positioned on the back reflection layer. The second reflection layer contacts the first reflection layer. The second electrode is electrically connected to the first reflection layer through the opening.

The present invention relates to a prism for inducing Brewster's angle transmission and a fluorescence detection apparatus for enhancing a signal-to-noise ratio using thereof, and more specifically, to a prism for inducing Brewster's angle transmission and a fluorescence detection apparatus for enhancing a signal-to-noise ratio using thereof, in which evanescent waves are generated when light is cast onto fluorescence material applied on a sample surface at an angle greater than a critical angle, and the evanescent waves are used as excitation light of fluorescence to induce total internal reflection of the light so that the light may pass through the prism at a Brewster's angle. Therefore, effects of the re-reflected light on the sample surface are removed, and a signal-to-noise ratio (SNR) is improved at the same time. In addition, the prism is miniaturized, and therefore, usage of the sample area and efficiency of the light amount are improved.

A door handle module and a door lock using the same are disclosed. The door handle module according to the present invention is provided with a hollow rotating piece, a torsion spring enclosing an outer circumference of the rotating piece and being engaged with the locking protrusion formed in the mounting recess by both ends thereof, and a hollow operating piece being fixed to the outside of the rotating piece and includes a shoulder edge formed on a circumference thereof to mount the both ends of the torsion spring and an operational edge formed on an inner circumference thereof to be connected to the handle. Accordingly, the handle that has been turned to open the door can be turned back by a recovery force of the torsion spring so as to be able to maintain its neutral position, and the structure of the door handle module and the door lock can be simplified.

The present invention relates to the method for tagging of carbohydrates with active methylene compound. Particularly, it relates to the method for tagging of carbohydrates with active methylene compound comprising the step of preparing carbohydrate conjugate in which carbohydrate and methylene compound are combined by mixing carbohydrate mixture and methylene compound under aqueous polar aprotic solvent containing amine base catalyst. The tagging method of the present invention does not need many kinds of chemical reagent and the reactions can be taken even in the presence of certain amount of impurities. So, it can be used for the analysis of oligosaccharide present in the various kinds of samples.
