For efficient electrochemical CO2 conversion, we demonstrated perovskite solar cell wired CO2 conversion process. The efficiency of perovskite solar cell was ~ 10 % with ~ 20 mA cm-2 and ~ 1.0 V. CO2 conversion process was performed with copper-based electrocatalysts and products were analyzed by Gas chromatography. The electrochemical analysis was employed with the 3-electrode system comprising with the electrocatalysts as a working electrode, Ag/AgCl as a reference electrode, and Pt mesh as a counter electrode. Electrochemical properties were characterized with linear sweep voltammetry, electrochemical impedance spectroscopy, and Tafel plot. |
