Abstract
A method for fabricating an absorbing layer of a solar cell and a thermal treatment device thereof adapted for forming an absorbing layer on a substrate are disclosed. The method includes the following steps. First, a solid-phase vapor source in a chamber and an absorbing layer precursor on a substrate are maintained by a predetermined distance. The solid-phase vapor source contains tin. The absorbing layer precursor contains copper, zinc, tin and sulfur. The temperature inside the chamber is raised to a forming temperature, so that the absorbing layer precursor forms an absorbing layer on the substrate.

26. A thermal treatment device, used for performing a thermal treatment on an absorbing layer precursor on a substrate of a solar cell, the absorbing layer precursor containing copper, zinc, tin and sulfur, the thermal treatment device comprising:
-
a chamber having a heating zone and a thermal treatment zone in sequence, the temperature in the heating zone is lower than the temperature in the thermal treatment zone, wherein a solid-phase vapor source is disposed in the thermal treatment zone, and the solid-phase vapor source contains tin; a mobile carrier movably disposed in the chamber, wherein the mobile carrier is adapted for moving from the heating zone to the thermal treatment zone along a first direction, and the substrate is disposed on the mobile carrier; and a temperature controller, assembled at the chamber, wherein the temperature controller is adapted for adjusting the temperature in the chamber; wherein, when the mobile carrier moves to the thermal treatment zone, the absorbing layer precursor on the substrate and the solid-phase vapor source are kept by a predetermined distance. - View Dependent Claims (27, 28, 29, 30, 31, 32, 33)
