Abstract:
PURPOSE: A method for preparing a cellulose phosphite compound is provided to suppress side reaction such as the degradation of a cellulose polymer chain or intermolecular cross-linking bond and to prepare a cellulose phosphite compound with excellent solubility in water. CONSTITUTION: A method for preparing a cellulose phosphite compound comprises the step of performing the phosphorylation of cellulose in the ionic liquid consisting of amine-based cations and phosphite-based anions. The amine-based cation is selected from the cations represented by chemical formula 1. In chemical formula 1, R1, R2, R3, R4, R5, R6, R7, and R8 are the same or different and represent a C1-6 alkyl group, C1-6 alkylcarboxylic acid group, C1-6 alkylester group, hydroxyl C1-6 alkyl group, dihydroxy C1-6 alkyl group, C1-6 alkoxy C1-6 alkyl group or phenyl group.
Abstract:
PURPOSE: A quantum dot sensitive solar battery and a manufacturing method thereof are provided to easily recover the supercritical fluid or the subcritical fluid including unabsorbed quantum dot precursor. CONSTITUTION: A quantum dot precursor(60) is introduced within a high pressure reservoir(11), and is dissolved by using the subcritical fluid or the supercritical fluid. The manufactured quantum dot precursor solution is transferred to a conductive film substrate(61) consisting of metal oxide introduced within the high pressure reactor, and is absorbed in metal oxide thin films. The quantum dot precursor solution which is not absorbed is transferred with the subcritical fluid or the supercritical fluid to the high pressure reservoir and recovered. The subcritical fluid or the supercritical fluid in a gas phase is eliminated from the high pressure reactor. The adsorbed quantum dot precursor is reacted with the compound including the second element forming the quantum dot.
Abstract:
Fabrication of thin film for solar cells using paste and the thin film fabricated thereby are provided to minimize consumption of a metal material by a paste or an ink for CIGS or CIS thin film. A Cu precursor and In precursor, and Ga precursor are mixed to manufacture a mixture(103). The mixture is appropriately heat-treated and then the precursor compound or oxide is formed. The precursor compound or oxide is mixed with a Se precursor and it is reacted to water-based solvent or alcoholic solvent and then a paste is obtained(105). After the paste is coated on the substrate, the substrate is heat-treated under the inert gas or the reducing gas.
