    摘要： Embodiments of the present invention generally relate to the fabrication of solar cells and more specifically to a buffer layer for improving the performance and stability of surface passivation of Si solar cells. Generally, a passivation layer stack containing a buffer layer (interlayer) is formed on a surface of the silicon-based substrate. In one embodiment, the passivation layer stack may be formed on the back surface of the substrate. In another embodiment, the passivation layer stack is formed on the back surface of the substrate and a front emitter region (light receiving surface) of the substrate.

    摘要： This invention involves a fiberglass composition containing the following components: SiO2, Al2O3, CaO, MgO, B2O3, F2, TiO2, K2O, Na2O, Fe2O3 and SO3. The weight percentage of each of the components are as follows: SiO2 58˜65%, CaO 20˜26%, Al2O3 9˜17%, MgO 0.5˜1%, B2O3 0˜5%, F2 0˜1%, TiO2 0.1˜1%, K2O+Na2O 0˜0.8%, Fe2O3 0.1˜0.5%, SO3 0˜0.6%. The ternary system, SiO2—Al2O3—CaO, is basis of the fiberglass composition in this invention, which also has low quantities of MgO and B2O3. In addition, the total amount of alkaline earth oxide and the proportional relationship between MgO and CaO are rationally designed, which helps to improve the mechanical strength, heat resistance, and chemical stability of the glass. It also has excellent manufacturing performance. Moreover, the raw materials of the fiberglass composition in this invention are low in cost, and the invention meets environmental protection requirements.

    摘要： A regenerated optical waveguide is fabricated by hydrogenating an optical waveguide (12) and exposing a grating section (28) to a UV laser beam interference fringe pattern (14) to form a Type I grating. The grating section (28) is exposed for a second period to erase the Type I grating, and then a third period to cause a regenerated optical waveguide grating to form. The resonant wavelength increases during the third period from being substantially the same as the final wavelength of the Type I grating.
