Australian researchers found that the next generation of solar cell efficiency at a record high

” White said: & other; When they are small, it is difficult to accurately measure them, but also can not represent what happens when the scale enlargement. At the Australian national university's official website announced recently, the researchers has opened up a new field in the solar cell conversion of energy efficiency, people can see prospects for the future development of the technology. Silicon plant harm & other; A kind of high efficiency solar cells must be able to produce high voltage and high current at the same time. ” White said, its ultimate goal is to combine the perovskite and silicon into tandem solar cells, & other; Put the two materials together, may be more efficient than a materials & throughout; 。 “ Currently 95% of the solar cell is made of silicon. ” Peng Jun said, & other; Although it is difficult to realize these two functions at the same time, the battery in the nano structure layer makes this possible. The research achievements of the team got the CSIRO photovoltaic performance laboratory of independent verification. Because silicon can't get better, so we always focus on the other half of & ndash; — Perovskite. ” “ In terms of perovskite solar cells, the energy conversion efficiency is now competitive, photovoltaic energy storage power station and the cost is one of the big selling point. For example, they must be able to use 25 to 30 years in extreme temperatures. It is a very good material, but in the next five to 10 years, it will achieve maximum efficiency. Perovskite materials contain abundant and cheap chemical elements, including carbon, hydrogen, nitrogen, iodine and lead, etc. ” White said, & other; But if you want to make really good tandem solar cells, and must make the two types of cells work as efficiently as possible. White and his team over the years has been committed to improving the perovskite solar cells. The lab is in the southern hemisphere only a certified for the efficiency of solar cells has reached the international standard laboratory.

　　” “ Solar battery research and development, mainly based on three points, that is, let the battery it efficient, stable and cheap. ” Therefore, our research results in a lot of people think the smallest scale & ndash; — A square centimeter is the highest. Crystalline silicon photovoltaic modules crystalline silicon photovoltaic modules battery online monitoring equipment now the real challenge is to make them stable enough, so that can be used on the roof. This means that the injection battery of 21 is in the sunlight. 6% will be converted to energy?

　　” That white & other; In this view, perovskite batteries are the future of solar cells, has been a focus of attention in the next generation of batteries. In order to achieve this record as a result, photovoltaic power station Peng Jun subsidy policy has developed a new type of nano structure materials. Thomas & middot; According to white, and the contrast of currently installed on the roof of the typical solar panel efficiency is only 17% to 18%. The school of engineering and computer science professor Thomas & middot; Dr Wright, Peng Jun ( Transliteration) The researchers created a 21. 6% of the energy conversion efficiency of a new record, this is the perovskite battery to achieve the highest efficiency of a certain size?
