Abstract: PURPOSE: A method for manufacturing a thin film type solar cell is provided to improve the quality of a solar cell by implementing mixing, temperature raising, and ultrasonic wave processing processes with respect to I-II-IV-VI-based materials. CONSTITUTION: A mixed solution is manufactured by mixing I-family materials, II-family materials, IV-family materials, VI-family materials, and a solvent(S1). The temperature of the mixed solution is raised, and the mixed solution undergoes an ultrasonic wave process(S2). A product obtained through the ultrasonic wave process is dried to obtain I-II-IV-VI-based semiconductor nanparticles(S3). The I-II-IV-VI-based semiconductor nanoparticles are redispersed in the solvent to form a semiconductor nanoparticle solution. The semiconductor nanoparticle solution is applied on a substrate and is thermally treated to form an absorbing layer.

Abstract: A method for preparing a TiO2 photocatalyst doped with platinum ions capable of effectively decomposing various recalcitrant organic matters under the irradiation of a visible light by doping platinum ions capable of making a new trap site between energy band gaps of TiO2 is provided. A method for preparing a TiO2 photocatalyst doped with platinum ions sensitive to a visible light comprises: a step(a) of agitating a solution containing a Pt-ion precursor and a solution containing a TiO2 precursor, thereby doping Pt ions in TiO2 lattices to form TiO2 doped with Pt ions in a sol state; a step(b) of performing flash evaporation of the TiO2 doped with Pt ions in a sol state at 70 deg.C to form TiO2 doped with Pt ions in a powered state; and a step(c) of firing the TiO2 doped with Pt ions in a powered state at 100 to 500 deg.C for 4 hours. The Pt ions are doped into the TiO2 lattices at a ratio of 0.1 to 5% based on the number of titanium atoms. The step(a) comprises: a step(a1) of dissolving chloroplatinic acid(H2PtCl6) into water and adding nitric acid to the dissolved solution; and a step(a2) of dropping a solution in which titanium tetraisopropoxide is dissolved into ethanol into the solution formed in the step(a1), and stirring the resulting solution.
