研究了SnO<inf>2</inf>透明导电膜表面平均晶粒尺寸与a-Si：H太阳电池转换效率的关系。在不同晶粒尺寸的SnO<inf>2</inf>/玻璃衬底上制备了a-Si：H太阳电池。晶胞结构为glass/p（SiC）-i-n/Al，有效晶胞面积为4 × 10<sup>-</sup> 2cm<sup>2</sup>。随着晶粒尺寸从0.1 μ m增加到0.8μm，玻璃基板的反射率降低到约7%，短路电流从12 mA/cm 2增加到14 mA/cm<sup>2</sup>。在AM-100 mW/cm<sup>2</sup>下，使用平均晶粒尺寸为0.4 µm的乳白色SnO<inf>2</inf>薄膜实现了7.9%的转换效率。
The relationship between average grain size on the surface of SnO<inf>2</inf>transparent conductive film and conversion efficiency of the a-Si:H solar cell was investigated. a-Si:H solar cells were fabricated on SnO<inf>2</inf>/glass substrates with various grain sizes. The cell structure was glass/p(SiC)-i-n/Al and the effective cell area was 4 × 10<sup>-2</sup>cm<sup>2</sup>. The reflectivity from the glass substrate was reduced to about 7 percent with increasing the grain size from 0.1 to 0.8µm, and the short-circuit current was inceased from 12 to 14mA/cm<sup>2</sup>. A 7.9 percent of conversion efficiency was achieved using milky SnO<inf>2</inf>film of 0.4-µm average grain size at AM-100mW/cm<sup>2</sup>.
