摘要:
Embodiments of the present invention generally provide methods and apparatus for material removal using lasers in the fabrication of solar cells. In one embodiment, an apparatus is provided that precisely removes portions of a dielectric layer deposited on a solar cell substrate according to a desired pattern and deposits a conductive layer over the patterned dielectric layer. In one embodiment, the apparatus also removes portions of the conductive layer in a desired pattern. In certain embodiments, methods for removing a portion of a material via a laser without damaging the underlying substrate are provided. In one embodiment, the intensity profile of the beam is adjusted so that the difference between the maximum and minimum intensity within a spot formed on a substrate surface is reduced to an optimum range. In one example, the substrate is positioned such that the peak intensity at the center versus the periphery of the substrate is lowered. In one embodiment, the pulse energy is improved to provide thermal stress and physical lift-off of a desired portion of a dielectric layer.

A display method and an electronic apparatus include a display unit with various kinds of different display modes, so that when the current display mode of the display unit is the first display mode, the first application in the electronic apparatus is initiated, and then the electronic apparatus detects the first parameter information of the first application, and then determines the correspondence relationship between the first parameter information and the display modes, determines the second display mode corresponding to the first parameter information, and adjusts the display unit from the first display mode displayed currently to the second display mode at last. Determining the display modes according to different applications running in the electronic apparatus increases the display effect of the electronic apparatus and reduces the power consumption of the display of the electronic apparatus.
