    摘要: Disclosed are a solar cell and a method for manufacturing the same. The solar cell comprises asymmetric nanowires each of which has an angled sidewall, and thus incident light can be concentrated at a p-n junction portion by means of a total reflection phenomenon of light caused by the difference between the refractive indices of a semiconductor layer and a transparent electrode layer, and light absorption may increase due to an increase in the light travel distance, thus improving photoelectric efficiency. Further, the method for manufacturing the solar cell involves etching a substrate and integrally forming the substrate and a p-type semiconductor layer including the asymmetric nanowires each of which has the angled sidewalls, thereby enabling reduced manufacturing costs and simple and easy manufacture of the nanowires having the angled sidewalls.

    摘要: A switching mode power supply includes an EMI filter unit, a PFC unit, a DC/DC unit, a PFC controller including a feedback stage to which a link voltage at an output side of the PFC unit is fed back and an overvoltage protection stage, a DC/DC controller generating a burst mode operation signal in a light-load or no-load condition, an error signal generation unit for sensing an output voltage of the power supply to generate an error signal, and a control unit for enabling the PFC unit to operate in a burst mode by connecting the overvoltage protection stage and the feedback stage. When the error signal is smaller than a predetermined value, the DC/DC controller generates the burst mode operation signal. When the link voltage fed back to the feedback stage exceeds a threshold voltage of the overvoltage protection stage, the PFC controller deactivates the PFC unit.
