  • Publication number: 20180127875
    Abstract: An apparatus for performing a selenization and sulfurization process on a glass substrate is introduced. A low-cost, non-toxic selenization and sulfurization process is performed on a large-area glass substrate in a normal-pressure environment with the apparatus to turn element selenium or sulfur into small molecules of high activity at high temperature by pyrolysis or by plasma, especially linear atmospheric pressure plasma. The process is finalized by dispersing the selenium or sulfur molecules uniformly and allowing the glass substrate to undergo reciprocating motion precisely, thereby achieving large-area, uniform selenization and sulfurization of the one-piece glass substrate.

  • Publication number: 20170155005
    Abstract: A selenization/sulfurization process apparatus for use with a single-piece glass substrate is characterized by two chambers for heating up a glass substrate quickly and performing selenization/sulfurization on the glass substrate to not only prevent the glass substrate from staying at a soaking temperature of a softening point for a long period of time but also increase the thin-film selenization/sulfurization temperature according to the needs of the process to thereby reduce the duration of soaking selenization/sulfurization, save energy, and save time. The glass substrate undergoes reciprocating motion in the chambers to not only attain uniform temperature throughout the glass substrate but also distribute a selenization/sulfurization gas across the glass substrate uniformly during the selenization/sulfurization operation. The recycled liquid selenium/sulfur and inert gas are reusable to thereby reduce material costs.

  • Publication number: 20160293789
    Abstract: The present disclosure relates to a vapor deposition equipment for fabricating CIGS film, in which a Se vapor deposition module, a In/Ga linear vapor deposition module and a Cu linear vapor deposition module are integrated in an identical vacuum chamber, used for fabricating the CIGS absorber layers on a flexible solar cell substrate by an automatic manufacturing process in accordance with an unwinding module, a heating device, a heat reducing device, a speed-controlling roller module, a cooling module, and a winding module. Moreover, in the present disclosure, a film thickness measuring module is used for measures the thickness of the CIGS chalcopyrite crystalline film on the flexible solar cell substrate, and the thickness data of the CIGS chalcopyrite crystalline film would be transmitted to the electromechanical control module for being references of the parameter modulation of following fabricating process, and such way is so-called APC (Advanced Process Control) system.

  • Publication number: 20160172220
    Abstract: A selenization process apparatus for a glass substrate includes a first heating unit disposed in a chamber; a conveying heating module disposed in the chamber and below the first heating unit to not only drive the glass substrate to move but also heat the glass substrate, wherein a thermal mark otherwise formed as a result of contact between the conveying heating module and the glass substrate is reduced with an inert gas; a selenium gas feeding module connected to the chamber to introduce selenium gas into the chamber; and a gas recycling module connected to the chamber to recycle the selenium gas and the inert gas. The glass substrate is prevented from staying at a soaking temperature above the softening point for a long period of time. Selenization temperature is increased to speed up the selenization process. The selenium gas and the inert gas are recycled and reused.

  • Patent number: 8330075
    Abstract: The invention discloses a control method of optical cutting. A laser processing module is used to generate a cutting heat source and an auxiliary heat source. The control method of optical cutting includes the steps of determining a cutting path on the work piece first; then calculating a thermal stress distribution along the cutting path according to a heating condition; next determining an irradiation condition for the auxiliary cutting heat source according to the thermal stress distribution induced by the cutting heat source; and irradiating the work piece along the cutting path with the cutting heat source and simultaneously irradiating the work piece with the auxiliary cutting heat source. The cutting of the work piece is therefore finished.
