Research and Characterization of an Absorber Layer Material ---Cu(In,Ga)Se2 Sputtered on Polyimide Substrate in Material Engineering Yongping Zhao1, a, Congchun Zhang1,b, Guifu Ding1,c and Yongliang Wang1,d 1 National Key Laboratory of Science and Technology on Micro/Nano Fabrication Technology, Research Institute of Micro/Nano Science and Technology, Shanghai Jiao Tong University, 200240,Shanghai, China azyp2010sjtu@hotmail.com,bzhcc@sjtu.edu.cn(corresponding author), cgfding@sjtu.edu.cn, dwyl5617005@163.com Keywords: polyimide; Cu(In,Ga)Se2; solar cell; electric resistivity.
Cu(In,Ga)Se2 is a very important type of absorber layer material for high efficiency solar cells in material engineering.
In all the deposition method, such as co-evaporation, selenization, co-sputtering, electro chemical deposition and screen printing method, co-evaporation and selenization method can get the better quality of CIGS thin film among them, but when the CIGS film growth temperature is blow 400 ℃, the three-stage is inefficient for solar cells[8].RF magnetron sputtering is a commonly used method for the preparation of thin film materials, it is simple and easy to manipulate.
By heating substrate can increase adhesion between the film and substrate, promote CIGS grain to grow up, Sputtering pressure increased and sputtering temperature rose can cause the resistivity increasing. the film adhesion decreased with decrease of air pressure, appropriate Ar pressure is important, which is significant to make high efficiency solar film cells in material engineering.

At the same time, proceed strict management and distribution of project funds, all materials purchased all open tendering procedures, put an end to all violations, actively cooperate with the audit department and finance department tracking audit drinking water safety project, project budget, step by step award of bid, completed award of bid, all must be strictly and prevent deformity engineering appearance, will let the limited funds to do more for the people. 2.4 Adjust measures to local conditions, scientific planning, careful construction, strictly the “four key” For each project must be through scientific analysis and demonstration, multiple scheme comparison according to the local natural conditions, the economic and social development, eventually determine the type and scale of drinking water and water supply engineering reasonable.
To strengthen the construction of quality management, we should conscientiously do a good job of each key link, mainly to do good “four key”.
Namely: material and equipment quality, construction, engineering quality and engineering completion acceptance.
The main engineering materials will been unified by the procurement of government; the establishment of quality supervision system of drinking water project tendering system and project, open tendering to drilling engineering construction team; in strict accordance with the drawings, design documents, engineering card and the related standard construction, the key parts of the important hidden engineering or engineering are timely check and acceptance, and at any time should accept supervision by the masses, and to be passed acceptance inspection, it can enter the next procedure.
The latter must be used for classes, there are plans to implement, make the limited funds to play as much as possible engineering benefit.
