NOVELTY - The thin film solar cell module comprises a first light-transmitting substrate, a set of thin film solar cells located in an upper portion of the first light-transmissive substrate, a second light-transmissive substrate sealing the thin-film solar cells, a first electrode located on the first light-transmissive substrate, a photoelectric conversion unit located on the first electrode, and a second electrode electrically connected to the thin-film solar cell. The first electrode is contacted with a p-type doped layer of the photoelectric transform portion.    USE - Used as a thin film solar cell module.    ADVANTAGE - The solar module increases an amount of the incident light in the solar cell, so that the efficiency of the solar cell module can be increased, the charge transfer efficiency is improved, and the leakage current can be reduced. The second electrode is formed using the transparent conductive oxide, so that the manufacturing cost of the solar cell module can be decreased.    DETAILED DESCRIPTION - The thin film solar cell module comprises a first light-transmitting substrate, a set of thin film solar cells located in an upper portion of the first light-transmissive substrate, a second light-transmissive substrate sealing the thin-film solar cells, a first electrode located on the first light-transmissive substrate, a photoelectric conversion unit located on the first electrode, and a second electrode electrically connected to the thin-film solar cell. The light is injected through the electrodes, where the electrodes include a single layer coating film made of transparent conductive oxide including aluminum-doped zinc oxide or a poly coating layer of aluminum and the zinc oxide. The aluminum-doped zinc oxide of the second electrode has the n-type conductivity. The photoelectric transform portion is provided with a p-type doped layer, an intrinsic layer and n-type doped layer, where the first electrode is contacted with the p-type doped layer of the photoelectric transform portion.
