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. |
