Methods of manufacturing a solar cell module are provided. The method may include forming lower electrodes on a substrate, forming a light absorption layer on the lower electrodes and the substrate, patterning the light absorption layer to form a trench exposing the lower electrodes, and forming window electrodes using a conductive film. The conductive film extends from a top surface of the light absorption layer to a bottom of the trench along one-sidewall of the trench and is divided at another-sidewall of the trench.
Abstract:
The present invention provides a method for manufacturing solar cells and the solar cells manufactured thereby. The method is capable of manufacturing flexible solar cells simply, by attaching a flexible substrate on a second electrode after forming multiple layers such as a copper indium gallium selenide (CIGS) absorption layer on a sacrificial substrate under a high temperature process. Additionally, a separation film is removed by a laser or by selective wet etching after the attachment of the flexible substrate. Therefore, flexible CIGS solar cells having high efficiency can be achieved.
Abstract:
There is provided an apparatus for irradiating a beam at a user's eye gaze point and an operation method thereof. The apparatus includes an eye gaze point detecting part analyzing a movement of a user's pupils and detecting the user's eye gaze point, and a beam irradiation part irradiating a beam at the user's eye gaze point detected by the eye gaze point detecting part. The apparatus detects the user's current eye gaze point and irradiates the beam at the user's detected eye gaze point, thereby allowing for the performance of desired control with greater accuracy.
