单晶硅和多晶硅太阳能电池组件目前占全球光伏市场的80%至90%。原因是与新兴技术相比，这种太阳能电池的稳定性，鲁棒性和可靠性。然后，在中期，硅太阳能电池将继续发挥其大规模地面应用的重要作用。一种重要的方法是通过沉积非晶硅层来开发在低温（低于300摄氏度）下处理的硅太阳能电池，目的是钝化硅表面，并避免在高于800摄氏度的温度下处理时硅遭受的退化。这种太阳能电池被称为HIT电池（具有本征薄非晶层的异质结）并且已经商业化生产（Sanyo Ltd.），达到20%以上的效率。在这项工作中，HIT太阳能电池模拟的手段AMPS-1D，这是一个程序开发的宾夕法尼亚州立大学。我们将讨论AMPS-1D模拟这种结构所需的修改，因为这个程序明确地没有考虑到界面状态的高界面密度发生在非晶硅异质结。(C)2009 Elsevier B.

Mono- and poly-crystalline silicon solar cell modules currently represent between 80% and 90% of the PV world market. The reasons are the stability, robustness and reliability of this kind of solar cells as compared to those of emerging technologies. Then, in the mid-term silicon solar cells will continue, playing an important role for their massive terrestrial application. One important approach is the development of silicon solar cells processed at low temperatures (less than 300 degrees C) by depositing amorphous silicon layers with the purpose of passivating the silicon surface, and avoiding the degradation suffered by silicon when processed at temperatures above 800 degrees C. This kind of solar cells is known as HIT cells (hetero-junction with an intrinsic thin amorphous layer) and are already produced commercially (Sanyo Ltd.), reaching efficiencies above 20%. In this work, HIT solar cells are simulated by means of AMPS-1D, which is a program developed at Pennsylvania State University. We shall discuss the modifications required by AMPS-1D for simulating this kind of structures since this program explicitly does not take into account interfaces with high interfacial density of states as occurs at amorphous-crystalline silicon hetero-junctions.
