Title:
THIN FILM TYPE SOLAR CELL AND METHOD FOR MANUFACTURING THE SAME
Document Type and Number:
WIPO Patent Application WO/2012/044006
Kind Code:
A3
Abstract:
Disclosed is a thin film type solar cell with superior efficiency and a method for manufacturing the same. The thin film type solar cell includes a substrate, one or more front electrodes arranged on the substrate such that the front electrodes are spaced from one another through a first trench, a semiconductor layer arranged on the front electrode, wherein a part of the semiconductor layer is removed by a second trench adjacent to the first trench, and one or more rear electrodes arranged on the second trench and the semiconductor layer such that the rear electrodes are spaced from one another through a third trench adjacent to the second trench, wherein the semiconductor layer include one or more connection members which are adjacent to the second trench and are divided by the second trench. Based on such configuration, the thin film type solar cell and the method for manufacturing the same provide superior photoelectric transformation efficiency by connecting semiconductor layers arranged at both sides of the second trench through the connection member.
