Recently, the United States, University of Illinois at Urbana - Champaign (University of Illinois at Urbana-Champaign) of the John Rogers (John Rogers), led by scientists discovered a new high-efficiency silicon solar cell production. This means the production of silicon solar cells is the flexibility and scalability to roll in pencil, a transparent and even as the building and automotive glass windows of colorants laptop battery  .

Published in the online journal “Nature - Materials” (Nature Materials) on a report that a new type of method can be used to the traditional silicon processing, is about to cut crispbread fragile silicon micro-thin ultra-fine Silicon, and then carefully transfer them to another extension of the flexible material on the surface.

The new leader of the research Rogers said: “We can make super-thin silicon can be attached to the plastic on any curl. Can also make silicon thin film or a film-like, glass, construction incorporation. This Building for the use of solar battery energy has become a platform opens up space. ”

As the global oil prices, coupled with people’s concerns about global warming, greatly increased the demand for solar cells.

Many of the world, such as Japan consumer electronics maker Sharp Corporation (Sharp Corp) and the German photovoltaic cell giant Q’s (Q-Cells) have a thin film solar cell production, however, this type of thin film solar cells in solar energy will be converted to electrical energy On the general efficiency of less than traditional solar cells.

Rogers said the technology used in the traditional silicon, they are “rugged, high efficiency, however, now appears to be too rigid and therefore fragile.” Rogers they adopted a method of etching silicon to deal with these Hp battery   . In a large silicon surface Guaxia small debris, the debris than the thin silicon wafers would also like to book 10 times to 100 times, and because of the small size, more user-friendly.

Guaxia silicon debris, the equivalent of a “rubber stamp” of these devices Zhanqu debris, and then they will be “printed” into other substances on the surface.

Rogers said: “These Guaxia Lai silicon debris as ink. Guaxia debris after the big silicon thin silicon surface has become the ’stamp pad’. Just ’seal’ to ’stamp pad’ in the silicon debris’ India ‘to other objects to the surface. ”

He said that as long as the final step in the electronic equipment used in solar cells will power Export it  HSTNN-LB31 .

Silicon material to increase the flexibility of making silicon solar cells more lightweight, easy to carry. Rogers looking forward to the future of silicon solar cells “can be rolled up like a carpet into the same truck.”

He said that the newly established North Carolina’s Durham County Semprius is the registration of the technical consultation.

Rogers said: “We only change the way we have the advantage of familiar things.”
