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 removes portions of a dielectric layer deposited on a solar cell substrate according to 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.

摘要： The present invention relates to solar cells and discloses a difluoro benzotriazolyl solar cell material and preparation method and use thereof. The solar cell material is represented by formula (I), wherein both R1 and R2, are C1 to C20 alkyl, and n is an integer from 10 to 50. In the difluoro benzotriazolyl solar cell material, since the 1,2,3-benzotriazole solar cell material contains two fluorine atoms, the HOMO energy level is reduced by 0.11 eV, while the fluorine-substituted 1,2,3-benzotriazole has two imido groups with electron-withdrawing ability; the fluorine-substituted 1,2,3-benzotriazole is a heterocyclic compound with strong electron-withdrawing ability, and an alkyl chain can be easily introduced to the N-position of the N—H bond of the benzotriazole. The functional group of the alkyl chain can improve the solar energy conversion efficiency, thus solving the low efficiency problem of solar cells made of the solar cell material.
