Abstract：The main subjects of this project are to develop new type silicon based absorption materials for wide spectrum utilization in high efficiency multi-junction solar cells. The approaches include modifying the band gap using amorphous and micro-crystalline silicon germanium thin film， improve the opto-electronic properties using polycrystalline silicon thin film with large grains and splitting the band gap using new concept intermediate band materials. The depth investigation and innovation on new type absorption materials will provide a scientific basis for the realization of the main target of high efficiency silicon thin film solar cell based on broad spectrum utilization.
Key Words：Silicon based thin film； Wide band； Silicon germanium material； Polycrystalline silicon thin film； Intermidiate band material
