Abstract:
A method of manufacturing a non-single-crystal silicon or silicon alloy thin film solar cell, which comprises laminating together (a) a first-conductivity-type layer comprising mainly microcrystalline phases, (b) an intrinsic i-type semiconductor layer comprising mainly microcrystalline phases, and (c) a second-conductivity-type layer of a reverse-conductivity-type to said first-conductivity-type layer, to form a lamination layer comprising mainly microcrystalline phases, on a substrate coated with a conductive film, and forming a transparent electrode and a metal grid electrode, said method comprising the steps of:forming a first part of said lamination layer at a first substrate temperature that prevents formation of amorphous phase at an initial stage of film formation, and forming the rest of said lamination layer thereon at a second substrate temperature higher than said first substrate temperature that (a) increases crystal grain size to improve crystallinity and photoelectric characteristics of the film, and (b) anneals the first part of said lamination layer.
