Zusammenfassung:	A thin-film photovoltaic cell having a high photoelectric conversion rate and a preparation process therefor. The thin-film photovoltaic cell comprises a transparent substrate (10) and photovoltaic units provided on the transparent substrate (10) in a mode of facing towards a display module; the photovoltaic unit provided in a display area comprises a transparent front electrode (20) provided on the transparent substrate (10), a light absorption layer (30) provided on the transparent front electrode (20), and a transparent back electrode (40) provided on the light absorption layer (30); the photovoltaic unit provided in a non-display area comprises a transparent front electrode (20) provided on the transparent substrate (10), a light absorption layer (30) provided on the transparent front electrode (20), and a metal back electrode provided on the light absorption layer (30). By configuring the front electrode and the back electrode corresponding to the display area of the display module to be transparent, var
