Thin film type Solar Cell and method of manufacturing the smae, and Thin film type solar cell module and Power generation system using the same

摘要

The present invention, in the thin film solar cell made of the front electrode on a substrate, the semiconductor layer and the back, including the electrode is a unit cell having the thin-film solar cells are in at least one of the first unit cell formed by the first cell width a first unit cell sets and at least is made to a second unit cell set comprised of a second unit cell, the first unit cell, a set formed by the first cell widths and different from the first cell width consisting of a unit cell as occupies 80 to 95% of the total area of, on the thin-film solar cells to the second unit cell set it is characterized in that account for 5-20% of the total area of ​​the unit cell, ; The present invention is full to enhance the short-circuit current of a relatively low unit cell by forming larger, the energy conversion efficiency than the cell width of the energy conversion efficiency is relatively low unit cell cell width is relatively large unit cell energy conversion efficiency of the implement a uniform energy conversion efficiency in the unit cell, and thus has the effect of enhancing the energy conversion efficiency of the thin-film solar cell. ; Thin-film solar cell, conversion efficiency, cell width
