Abstract: The present invention relates to a colorimetric detection of a target material based on a hydrogel particle. A colorimetric detection of a target material based on a hydrogel particle according to the embodiment of the present invention comprises the steps of: reacting a sample containing the target material with the hydrogel particle, which is loaded on the inside with a probe that specifically binds to the target material; and accumulating and amplifying an insoluble colorimetric material in the hydrogel particle so as to label the target material bound to the probe. Here, the hydrogel particle is made of a polymer network, the probe is loaded by binding to the polymer network, and the insoluble colorimetric material is fixed to the polymer network.

Abstract: Disclosed is a method for manufacturing a multi-junction solar cell including forming a lower cell, depositing a metal thin film layer on the lower cell, heat-treating the metal thin film layer to form a recombination layer and an intermediate charge transport layer, and forming an upper cell on the intermediate charge transport layer. After depositing a metal thin film on top of the lower cell, the deposited metal thin film is heat-treated at a high temperature, so that metal atoms in the metal thin film diffuse to the top of the lower cell to form the recombination layer of silicide at an interface between the metal thin film and the lower cell, and at the same time, oxygen atoms diffuse into the metal thin film to form metal oxide (the charge transport layer) at a surface of the metal thin film.
