THE FABRICATION METHOD OF ELECTRODE FOR SOLAR CELL

摘要

PURPOSE: A method for manufacturing an electrode is provided to the manufacture a device with high crystallization by controlling the crystalline degree of a photoactive layer. CONSTITUTION: Spray solutions are made by solving electron donor organic material and electron acceptor organic material in a solvent. A photoactive layer is formed by electrically spraying spray solutions on a glass substrate with a transparent electrode. A mixing ratio of an electron donor organic material and an electron acceptor organic material is 9:1 or 1:9. The crystalline degree of the photoactive layer is controlled. A band gap of the electron donor organic material is 2.5 to 0.8 eV.
