研究了氢化硅n层的材料特性及其对非晶硅太阳电池性能的影响。通过优化沉积工艺参数,可以得到具有高电导率、低激活能和宽带隙的纳米Si微晶镶嵌在a-Si:H基体中的混合相层。将混合相层叠层到a-Si:H电池中可以显著提高开路电压(Voc),最高可达0.95V,比a-Si:H层或微晶硅层的电池分别高约50 mV和100 mV。本文还讨论了混合相层对Voc增强的可能解释。到目前为止,在衬底温度高达220 °C、a-Si:Hi层厚度为300 nm的条件下,获得了9.4%的初始效率,最高Vc0.945 V,FF0.70,Jsc14.2 mA/cm 2。
Material properties of hydrogenated siliconn-layer and their impact on amorphous silicon (a-Si:H) solar cell are studied. By optimizing deposition parameters, mixed-phasen-layer with nanometer-sized Si crystallites embedded in a-Si:H matrix can be obtained, which demonstrates higher conductivity, lower activation energy and wider bandgap. Incorporating the mixed-phasen-layer into a-Si:H cell can significantly improve the open circuit voltage (Voc) up to 0.95 V, which is approximately 50 mV or 100 mV higher than those cells with a-Si:Hn-layer or microcrystalline siliconn-layer, respectively. The possible explanations ofVocenhancement brought by the mixed-phasen-layer have also been discussed. Up to now, we have achieved an initial efficiency of 9.4% with highVocof 0.945 V,FFof 0.70 andJscof 14.2 mA/cm2with a-Si:Hi-layer thickness of 300 nm and substrate temperature as high as 220 °C.
