If it can really commercial, then this may be another milestone in the history of solar energy. In our knowledge, solar cells are typically made of silicon and use only about 20% of the sun's rays; even the most efficient solar cells documented are only 25%, and that solar Batteries are generally made of rare and toxic materials. How to improve the utilization of the sun's rays and to adopt low-cost and environment-friendly materials has always been a problem that scientists are tirelessly waiting to overcome. A scientist from Oslo University in Norway presented a solution that seemed viable. According to EnergyLive, the new solar cell developed by Professor BengtSvensson uses nanotechnology to combine two layers of different materials to absorb more sunlight. The specific practices are as follows: The first layer of solar cells from the conventional silicon composition; the second layer, then by the copper oxide nanoparticles, specifically to absorb blue light in the sun's rays. We all know that blue light is never absorbed by ordinary silicon solar panels. The experimental results show that with the combination of these two materials, the new solar panel will increase the utilization of solar rays to 40%. This doubles the power generation efficiency of today's conventional solar cells. Professor BengtSvensson told the media: "Compared with the current high-cost and poisonous solar cells, the new nano-solar cells are not only the most efficient solar cells in the world but also friendly to the environment." In addition, it should be noted that copper oxide, the material required for making such nano-solar cells, is common on earth without using expensive rare metals. This will greatly reduce the cost of production. According to the information disclosed by Professor BengtSvensson, the development of this new solar cell is part of Solhet, a well-known research and development project in Europe. Of course, at present the research and development of the project is still in the laboratory stage, waiting for a period of time from the actual commercial production.
