在容性耦合SF6/O2等离子体织构化处理的单晶Si衬底上旋涂P3HT(poly(3-hexylthiophene))以制作杂化太阳能电池,研究不同激发频率下得到的晶硅表面纳米织构对该杂化电池性能的影响。实验结果表明:激发频率的增大促使了电池表面反射率的降低,增强了杂化电池的光电转化效率。40.68 MHz激发频率下等离子体织构处理的单晶Si制成的杂化电池光电转换效率达到1.14%。此外,空气中存放时间对电池片性能影响的研究表明40.68 MHz织构的硅/P3HT杂化电池片具有较好的电池特性和稳定性。
P3HT (poly-3-hexylthiophene) was spin-coated on a single-crystal Si substrate capacitively coupled with SF6 / O2 plasma to fabricate a hybrid solar cell. The effects of different excitation frequencies on the surface of nanocrystalline silicon Structure of the hybrid battery performance. The experimental results show that the increase of excitation frequency leads to the decrease of cell surface reflectance and enhances the photoelectric conversion efficiency of hybrid cell. The photoelectric conversion efficiency of hybrid cell made of single-crystal Si plasma-textured at 40.68 MHz excitation frequency was 1.14%. In addition, studies on the effect of storage time in the air on cell performance show that the 40.68 MHz textured silicon / P3HT hybrid cell has better cell characteristics and stability.
