The new concept of solar cell has a revolutionary breakthrough
Sud ( Tü V Sü D ) PV global director Robert Puto points out that, in the field of renewable energy, solar energy because of its huge development potential talent showing itself, but the development of the industry is the biggest obstacle in the realization of economic feasibility and how to ensure the quality of products, solar panels, long-term reliability is its ability to be market acceptance of the key.
Tü V SUD group is a leading global renewable energy field testing, certification, testing, training and knowledge service provider. The group in the field of photovoltaic provides customers with a full range of services, from the traditional components, parts of the testing and certification to the factory inspection, now also provide such as salt, ammonia, PID ( system voltage endurance ), testing and certification services.
" We will continue to track the technology and standards development, the timely introduction of new test and service, as the photovoltaic industry to third party certification body due contribution. " Robert Puto says, " as the sectors of the global supervisor, I am honored to supervise, assist and urge the implementation of these projects. For example, I and my team not only with the manufacturers of solar panels for testing and certification, at the same time help contractors, installation companies and importers review supplier and OEM factories, including the ready to be shipped to the installation site of the goods for shipment inspection. In addition, we from the stage of research and development through testing and certification of photovoltaic industry support, including extended test project, provided as compared to prior standards more high degree of credibility, and strengthening the new product bankability. "
Notably, Robert Puto introduces two is in the development of a revolutionary concept, he thinks these two concepts can play a solar battery plate potential. These two concepts are : the third generation of photovoltaic cells and 3D solar panels.
On the third generation of photovoltaic cells, which contain various at the molecular level with semi conductive properties of the material, and the advantages are more obvious. First, the battery efficiency could be the first generation and the second generation of crystal silicon thin film photovoltaic 2-3 times; second, third generation photovoltaic cells using a lower price for high-throughput printing and coating technology, the technology in manufacturing period and less energy consumption lower equipment investment, thus than previous generations of lot third, low cost; the third generation of photovoltaic cells has flexibility, the higher light absorption can cause the thickness of only a few microns, and has high transparency, can be installed on windows.
" 3D solar panels are the advantages of shape but not performance. " Robert Puto. According to his introduction, and the 2D board different is, according to the prototype test, 3D solar panels can be captured to almost all irradiated on the solar panels of the sun.
The first 3D solar panels is by the Georgia Tech Research Institute in 2007 and designed. At present, many university and company on the new design, in March this year, Massachusetts Institute of Technology engineering professor Jeffrey Grossman and his team to design a new 3D solar panels. This vertical accordion type tower structure than the traditional plane arrangement of battery power generation amount per square feet to more than 20 times, and in cloudy or sunny power almost the same. This shape is achieved through a customized software analysis tool preferably. The software test of countless solar energy plate structure, so as to determine which structure capable of producing most of the electrical energy, and then to the highest performance structure for ease of manufacture, transportation and cost assessment.
However, Robert Puto, 3D board to succeed still need to overcome all kinds of obstacles on the commercial feasibility. With ordinary 2D structure are compared, tower structure covering the same area requires more solar panels, this will increase the cost of manufacturing. However, some people think that, 3D shape can reduce the solar tracking system needs, in order to offset the increased cost, but this idea is reality requires strict feasibility and reliability test can reach.
