  • Patent number: 6262389
    Abstract: A sheet of silicate glass having a thickness of 2 mm and composed mainly of SiO2, and containing Al2O3, B2O3, Na2O, F, etc., is immersed in a molten salt comprising a mixture of 50 mol % of silver nitrate and 50 mol % of sodium nitrate. Na ions in the surface of the glass are eluted, diffusing Ag ions in the molten salt into the glass. When a laser beam is applied to the glass substrate thus formed, the glass substrate is evaporated or ablated progressively from its surface. The glass substrate is processed to a smooth finish without causing cracking or breakage.

  • Patent number: 6248948
    Abstract: A solar cell module comprises a plurality of unit cells connected in series, each of the unit cells comprising in this order an electrode, a first semiconductor layer having a first conductivity type and a second semiconductor layer having a second conductivity type. The electrode has a region not covered with the first semiconductor layer. The second semiconductor layer has a main region and a subregion which are separated by a groove. The main region of the second semiconductor layer in one unit cell is electrically connected to the region of the electrode not covered with the first semiconductor layer in another unit cell adjacent to the one unit cell. The region of the electrode not covered with the first semiconductor layer in the one unit cell is electrically connected to the subregion of the second semiconductor layer in the another unit cell. With this structure, it is possible to simplify the formation of a bypass diode and therefore provide a solar cell module with high reliability at a low cost.
