The dehydrogenation treatment is executed at 700 to 900 deg.C in such a manner that the absolute pressure in the atmosphere is gradually reduced in a multistage. Moreover, the 1st dehydrogenation treatment is executed in such a manner that it is held for 1 to 30 min in a hydrogen partial pressure atmosphere of 1 Pa to 1 kPa.  Moreover, the absolute pressure is preferably controlled to 40 to 100 kPa in the 1st stage, to 300 Pa to 10 kPa of He or Ar in the 2nd stage and to <=150 Pa in the 3rd stage.

Title: Manufacture of thin film solar cell
Inventor: TAKEMURA KAZUO
IPC: G02B1/10
Filed: 1988-03-17
Abstract: PURPOSE:To enhance photoelectric conversion efficiency without an increase in the manufacturing steps by a method wherein an anti-reflection layer is formed on the incident side of a translucent insulating substrate and a layer for preventing diffusion of alkaline ions from the opposite side of the substrate is formed of the same material. CONSTITUTION:Translucent insulating films 2 and 7, lower than the translucent insulating substrate 1 in refraction index, are simultaneously formed on both sides of a translucent insulating substrate 1, respectively. Further, a semiconductor photoelectric conversion layer 4 is formed on a translucent insulating film 2, with a transparent conductive film 3 between the transparent insulating film 2 and semiconductor photoelectric conversion layer 4. An incident light beam 6 is guided to the semiconductor photoelectric conversion layer 4 without a loss thanks to the anti-reflection effect of the low refraction index translucent insulating film 2. The resultant current is efficiently taken out after passing through the transparent conductive film, which is adequately reduced in resistance thanks to the alkaline ion diffusion prevention effect of the low refraction index translucent insulating film 2 formed on the rear side, where it experiences no undesired consumption. This design increases the photoelectric conversion efficiency without any new manufacturing steps.
