The structure of natively textured SnO/sub 2/ films suitable for the transparent electrode of an a-Si:H solar cell was studied. An a-Si:H solar cell on the textured SnO/sub 2/ film, which had a columnar bulk structure with a (200) single X-ray diffraction peak, showed better open-circuit voltage (V/sub oc/) and fill factor (FF) with the relatively high short-circuit current density (J/sub se/) compared with a-Si:H solar cells on the other textured SnO/sub 2/ films with multiple X-ray diffraction patterns. The texture effect on the collection efficiency of the solar cell with textured front surface transparent conductive oxide (TCO) or textured back surface TCO was also studied. Texturing at the incident side TCO improved both short wavelength response (from 0.3 to 0.6 ..mu..m) and long wavelength response (from 0.6 to 0.8 ..mu..m) of an a-Si:H solar cell, while texturing at the back side improved only long wavelength response. The SnO/sub 2/ film with an average surface gain size around 0.2 ..mu..m or larger was effective for sufficient optical confinement of the incident light over a wide wavelength range from 0.3 to 0.8 ..mu..m.
