In the market, although the overall domestic solar overcapacity, working poor, reducing government support, but the international market, the United States and other countries has found a new solar photovoltaic cell applications. Such as the U.S. Department of Energy and the National Renewable Energy Laboratory, in 2010 chose Sapp Cornelius, a photovoltaic company as their incubator branch, initially incubator company received 1 million to three million U.S. dollars, these funds to develop their concepts and prototypes finished its work into the pilot project and to ensure the full use of the National Renewable Energy Laboratory scientist expertise to help them overcome obstacles to test reliability and validity. 

　　

　　Beginning in 2007, the date, the U.S. Department of Energy invested $ 50 million to make 35 new companies involved in solar photovoltaic incubator project, which is now up summer incubator is part of the National Renewable Energy Laboratory. Now, the total amount of private investment in these companies over 1.3 billion U.S. dollars, up 25-fold. For now this low-cost approach has been recognized by executives Sapp Cornelius companies, because it reduces the manufacturing costs by 50%, and it is for this reason attracted the favor of energy giant Siemens, in 2011 about the past Siemens bought the remaining 16% Sapp Andean shares, in terms of economics which is a venture capital investment of $ 20 million. 

　　

　　Here, you must really want to know the story about Sapp Cornelius company, which was founded at the University of Illinois (University of Illinois), the group John Rogers (John Rogers) professor and his leadership developed by transfer printing technology, which was originally intended to use the flexible electronics products, but soon discovered that the application of this technology Rogers can be concentrating photovoltaic (CPV) design, but would be more profitable. Sapp Cornelius cultivate temporary layer is carried out on the original GaAs substrate, and then, at this level, foster multi-junction solar cell structure. Then, the wafer was processed using a transfer printing process, remove the battery from the GaAs substrate, and transfer them to the interpolation on the wafer.
