摘要

我们提出了红外透射率和反射调制光谱的变化，反向偏置电压在各种非晶硅(a- si:H)为基础的引脚和最小的太阳能电池和二极管。光谱来源于两个本征层界面附近能级电荷状态的变化。不同界面的光谱差异很大，因此我们建议将其应用于太阳能电池制造中界面的非原位监测。测量结果也支持了磷掺杂的模型，即在通常用于太阳能电池制造的浓度下，磷通过掺杂复合物的形成发生。

Interfacial optical spectra in amorphous silicon based pin solar cells

We present infrared transmittance and reflection modulation spectra for changes in the reverse bias voltage across a variety of amorphous silicon (a-Si:H) based pin and min solar cells and diodes. The spectra originate with the change in charge state of levels near the two intrinsic-layer interfaces. The spectra vary significantly for differing interfaces, and we therefore propose their application to ex situ monitoring of the interfaces in solar cell manufacturing. The measurements also support the model that phosphorus doping occurs through dopant complex formation at the concentrations commonly used for solar cell fabrication.
