Title:
SEALING METHOD
Document Type and Number:
Japanese Patent JPS60163469
Kind Code:
A
Abstract:
PURPOSE:To improve the tact time of devices by not only improving the yield but also facilitating the method of temperature detection by a method wherein an infrared ray source is adopted for the heat source. CONSTITUTION:Solar cell elements 5-5 are connected in series and loaded on a substrate 6, and further a resin sheet is superposed; then, they are put on stoppers 10 and 10' of the lower mold 2. Next, the upper mold 1 with a diaphragm 3 made of soft heat- insulating rubber installed hermetically is assembled airtightly. Vacuum exhaust is started by means of vacuum exhaust pipes 8 and 9 at the same time. A glass plate 7 of high photo permeability is mounted on the most part of the bottom of the lower mold 2. When an infrared ray lamp 11 is lighted at the same time with the vacuum exhaust, an infrared ray is reflected by a condenser mirror 12 and the fuses the resin sheet 4 by heating via glass plate 7 by means of the energy of rays 13-13. At the same time, the vacuum degree of the upper mold 1 and the lower mold 2 is adjusted to about 1Torr or less by means of the vacuum exhaust pipes 8 and 9. When this fusion temperature amounts to a fixed temperature, release of the vacuum pressure of the upper mold to the atmospheric pressure leads the diaphragm 3 to desent as shown by the one-dot chain line of 3'; thus, the solar cell elements 5, 5'-5 can be sealed by adhesion to the substrate 6 with the fusion of the resin sheet 4.
