类单晶硅太阳电池制绒工艺及光致衰减现象研究

摘要

As a new solar cell material,further understanding the technology and performance of mono-like crystalline silicon solar cells is necessary.Acidic-alkaline texturing of the wafers is discussed,and then the light induced degradation of the solar cells based on conventional process is tested.The mono-like crystalline silicon solar cells show a relatively superior stability with the contrast of monocrystalline and multicrystalline silicon solar cells.Experiments show that mono-like crystalline silicon solar cells have certain advantages and broad prospect.%类单晶硅作为一种较新的太阳电池用硅材料，进一步了解类单晶硅太阳电池的工艺及性能显得非常必要，文中通过酸碱两步制绒法对类单晶硅的制绒工艺进行了探讨，然后对常规工艺制备的类单晶硅太阳电池进行了光致衰减实验，经过与单晶硅及多晶硅太阳电池的对比发现，类单晶硅太阳电池表现出了相对优越的稳定性。实验表明类单晶硅太阳电池具有一定的优势，其发展前景广阔。
