Abstract

The present invention relates to a CIGS solar cell having both transparency and flexibility and a method of manufacturing the same. The method of manufacturing a CIGS solar cell having both transparency and flexibility according to the present invention is characterized by including the steps of: preparing a carrier substrate on which a transparent polymer film is stacked; sequentially stacking a rear transparent electrode, a CIGS light-absorbing layer, and a front transparent electrode on the transparent polymer film; irradiating a long-wavelength laser to an interface between the rear transparent electrode and the CIGS light-absorbing layer in some areas to remove the CIGS light-absorbing layer and the front transparent electrode, thereby forming a light-transmitting region that exposes the rear transparent electrode; and irradiating a short-wavelength laser to an interface between the carrier substrate and the transparent polymer film to separate the carrier substrate and the transparent polymer film from each other.
