  • Publication number: 20140295612
    Abstract: A solar cell and a manufacturing method thereof are provided. A laser doping process is adopted to form positive and negative doping regions for an accurate control of the doping regions. No metal contact coverage issue arises since a contact opening is formed by later firing process. The solar cell is provided with a comb-like first electrode, a sheet-like second electrode corresponding to the doping regions to obtain high photoelectric conversion efficiency by fully utilizing the space in the semiconductor substrate. Furthermore, the sheet-like second electrode can be formed by a material having high reflectivity to improve the light utilization rate of the solar cell. The manufacturing process of the solar cell is simplified and the processing yield is improved.

  • Publication number: 20030234869
    Abstract: A camera for measuring the distance to an object is combined with a laser range measuring device by using a beam splitting device so as to simultaneously take the image of the object and measure the distance between the camera and the object. Using the focal length of the lens, the width and height of the image on the image detector, and the distance between the camera and the object, it is then possible to compute the width and height of the object according to the geometrical optics. By means of obtaining the speed of the image moving on the image detector, the camera of the invention further computes the speed of the object which is projected on a plane perpendicular to the optical axis of the lens.

  • Publication number: 20030197929
    Abstract: A binoculars for capturing images includes two optical systems and a image-capturing device installed in one optical system. The optical system having the image-capturing device includes a beam-splitting element, and the beam-splitting element divides a beam into two beams, wherein one beam is received by eye and another beam is received by the image-capturing device simultaneously. Consequently, the image-capturing device takes photos through the optical system of the binoculars.
