Hydrogen-argon mixed dilution has been applied for the deposition of boron-doped nanocrystalline silicon carbide (nc-SiC) thin films. The variations of structural, compositional, electrical and optical properties with the varying H/Ar ratio are systemically investigated through various characterizations. It is shown that by using H-Ar mixed dilution for deposition, B-doped nc-SiC thin film possessing both wide optical band gap (∼2.22 eV) and high conductivity (∼1.9 S cm) can be obtained at the H/Ar flow ratio of 360/140. In addition, the B-doped nc-SiC thin films are fabricated as the window layers of a-Si thin film solar cells, and the highest conversion efficiency (8.13%) is obtained when applying the window layer with the largest optical band gap energy.
氢氩混合稀释已应用于硼掺杂纳米晶硅碳化硅(nc-SiC)薄膜的沉积。通过各种表征系统地研究了结构、成分、电学和光学性质随H/Ar比变化的情况。结果表明,通过使用H-Ar混合稀释进行沉积,在H/Ar流量比为360/140时,可以获得具有宽光学带隙(约2.22 eV)和高电导率(约1.9 S cm)的硼掺杂nc-SiC薄膜。此外,将硼掺杂nc-SiC薄膜制成非晶硅薄膜太阳能电池的窗口层,当应用具有最大光学带隙能量的窗口层时,可获得最高转换效率(8.13%)。
