  溶液处理氢化非晶硅单结太阳能电池的制备

  摘要：

  氢化非晶硅太阳能电池是使用基于溶液的工艺制造的。pin结的所有硅层通过使用掺杂和非掺杂聚二氢硅烷溶液的旋铸方法堆叠。此外，采用真空条件下的氢自由基处理来降低硅膜中的自旋密度。经过这种处理，硅薄膜的电性能得到改善，太阳能电池在 AM-1.5G（100 mW/cm2）光照条件下的功率转换效率也从 0.01% 提高到 0.30%–0.51%。

  The perhydropentasilanes (H3Si)(4)Si and Si5H10 were chlorinated with SnCl4 to give chlorohydropentasilanes without destruction of the Si-Si backbone. Tetrachloroneopentasilane (ClH2Si)(4)Si (2) was prepared in high yield from (H3Si)(4)Si and 3.5 equiv of SnCl4, while Si5H10 and an equimolar amount of SnCl4 afforded a mixture of similar to 60% of ClSi5H9 (1) with polychlorinated cyclopentasilanes and unreacted starting material, which could not be separated by distillation. The selective monochlorination of Si5H10 was achieved starting from MesSi(5)Cl(9) (3; Mes = 2,4,6-trimethylphenyl) or TBDMP-Si5Cl9 (4; TBDMP = 4-tert-butyl-2,6-dimethylphenyl). 3 or 4 was successfully hydrogenated with LiAlH4 to give MesSi(5)H(9) (6) or TBDMP-Si5H9 (7), which finally gave 1 along with aryl-H and Si5H10 after treatment with an excess of liquid anhydrous HCl. All compounds were characterized by standard spectroscopic techniques. For Si-H derivatives, the coupled Si-29 NMR spectra were analyzed in detail to obtain an unequivocal structural assignment. The molecular structures of 2-4 were further confirmed by X-ray crystallography.

  Hydrogenated amorphous silicon solar cells were fabricated using solution-based processes. All silicon layers of the p-i-n junction were stacked by a spin-cast method using doped and non-doped polydihydrosilane solutions. Further, a hydrogen-radical treatment under vacuum conditions was employed to reduce spin density in the silicon films. Following this treatment, the electric properties of the silicon

  (CPS) – a liquid silicon precursor – was crystallized in situ at − 100 °C which allowed determination of the single crystal X-ray structure, showing short intermolecular distances below the sum of the v.d.Waals radii of the corresponding atoms. Further characterization included a thermal analysis with mass spectrometry (TG/MS) of the segregated species hydrogen, mono- and disilane.
