摘要： Provided are a CIGS solar cell and a method of fabricating the CIGS solar cell. In the method, a buffer layer exposing protrusions is formed. Then, a window electrode layer having an uneven surface conforming with the protrusions of the buffer layer is formed. Thus, an additional process for making the upper surface of a window electrode layer rough is unnecessary in order to decrease surface reflectance of incident sunlight and increase the solar cell efficiency, so that productivity can be improved.

摘要： Provided is a reflection-type optical modulation module. According to the reflection-type optical modulation module, an anti-reflective thin film is formed on the optical input/output side surface of a waveguide to reduce optical coupling loss, and also a high-reflective thin film is formed on the opposite side surface to feed back a modulated optical signal. Thus, even when the length of an absorption layer is shortened, a sufficient optical path length is available, and it is possible to obtain a sufficient extinction ratio. Since the optical path length is sufficiently long despite a reduction in the length of the device, capacitance is reduced, and high-speed operation is enabled. In addition, only one lensed optical fiber for optical input and output is used, and thus it is possible to reduce production cost and the number of installation processes. Furthermore, a small-sized and low-priced optical amplifier, instead of an external amplifier which is high priced and has a large volume, is integrated with an optical modulator so that production cost can be further reduced.
