摘要
A new structure of a-Si/ poly-Si tandem solar cell has been desiged and prepared. Amorphous silicon has been use as photovoltaic material of bottom cell. And polysilicon has been used as photovoltaic material of bottom cell.The combination of amorphous silicon and polysilicon extends the light range which can be used by solar cell. This structure improves the efficiency of solar cell greatly.
