THIN FILM TYPE SOLAR CELL AND METHOD FOR MANUFACTURING THE SAME, AND THIN FILM TYPE SOLAR CELL MODULE AND POWER GENERATION SYSTEM USING THE SAME

摘要

A thin film type solar cell with a plurality of unit cells connected in series is disclosed, wherein uniform energy conversion efficiency is maintained in all of the unit cells by improving the energy conversion efficiency in the unit cell with the relatively-low energy conversion efficiency, to thereby realize the improved energy conversion efficiency, the thin film type solar cell comprising the plurality of unit cells, each unit cell including a front electrode, a semiconductor layer, and a rear electrode sequentially deposited on a substrate, wherein the thin film type solar cell includes a first unit cell set including at least one first unit cell with a first cell width, and a second unit cell set including at least one second unit cell with a second cell width which is different from the first cell width, wherein the first unit cell set occupies 80 to 95% of an entire area of the unit cells, and the second unit cell set occupies 5 to 20% of the entire area of the unit cells.
