Flexible plastic back plate and strip plate for the integration of photovoltaic products, opens the door to new applications. So far, however, the integration of photovoltaic products produced by the photoelectric conversion efficiency of only the traditional process of crystalline silicon solar cells by half.
Recent Caltech physics professor Harry Atwater and his research team developed a new way of preparing batteries, this approach requires only very little silicon material. New technologies for the needs of only the traditional silicon technology 1% to 2%. "Our technology needs only the traditional process of silicon material 1/50 to 1/100 between", HarryAtwater says, "The technology to evenly The line-shaped silicon base classes, based on the absorption of light as well as the collection and conventional battery photoelectrons not much difference. "
Pipeline that smile stacked on a silicon substrate under the microscope, showing the brush shape. Since conventional batteries are based on expensive high-purity silicon material, so this design or have a high economic value.
What does this mean? Manufacturing performance in the integration of photovoltaic diy solar panels products with only 1% to 2% of the silicon material. As the cost of conventional crystalline silicon cells silicon accounted for 2/3 of the value of this technology for material savings showing its huge market potential.
Strengthen the control of light scattering and thus enhance the conversion efficiency of silicon photovoltaic china solar panel materials are the foundation, you might think so using less silicon material will affect the conversion power, the actual not as you think, Atwater said that this technology also has good optical conversion.
Flexible, sheet valued one important reason is that this material can be bent, you can imagine, they can be installed on top of any shape, such as: car roof top of the ship, or any non-flat surface.
Caltech professor, said his commercial operation of this technology is very optimistic, because this technology is based on conventional technology improvements, and not require large movements. He also said that this will help greatly reduce the cost of photovoltaic power.
Solar power is the most favorable place, anywhere in the world can receive sunlight, thick clouds of the Nordic whether or sunny in North Africa or Australia, and South Asia. This is the solar energy can go the root cause of the world.
