Solar power new translucent solar cells, renewable energy the next big breakthrough

【 Oilprice network on April 28 】 If the window to lighting and power generation, solar energy, is a perfect standard of life. Until recently, it was a wonderful but difficult to achieve. Make a thin layer of solar cells, thin film on the glass Windows is very easy, but very difficult to solar energy into electricity completely. A group of scientists from Australia to solve this problem.

the material chemistry professor jia chuck & middot; Jahi, g ( Jacek Jasieniak) Lead the team to develop a new kind of translucent solar cells. Compared with other translucent batteries, the most important difference is that: one of the components using organic conductive polymer. Compared with the original, common solar cell components, its stability is greatly enhanced.

the Spiro - initially OMeTAD material, very unstable, the perovskite solar cells convert light energy into electrical energy to produce a lot of adverse effects. Perovskite solar cells is what? This is a kind of material, the use of a mineral, collectively known as perovskite rather than silicon material. Compared with silicon, perovskite can battery costs are lower, the conversion efficiency is higher, but the stability is not high, the Australian team seems to be successfully solved this problem.

jahi, professor, said the new solar cell efficiency is impressive: & other; Rooftop solar energy conversion efficiency between 15% and 20%. New translucent cell conversion efficiency is 17%, but still can be transmitted more than 10% of the incident light, just meet people's needs. “ Power generation to have the window has been people's dream, now it seems that dream could achieve. ”

there is still a problem to solve. Glass, for example, transparency is lower, the more solar energy into electricity, therefore, if the construction industry to use the new batteries, architects need to consider the relationship between the transparent glass and conversion efficiency. But it may also mean only use glass will increase the proportion of the construction industry.

according to professor jahi the state of Virginia, new solar window can be as existing business as transparent glass Windows, every square metre about producing 140 watts of power. If we calculate all the area, such as a office building, so the solar energy is considerable.

the United States also has a private company recently reported the good news about solar window. The ubiquity of energy for the generation of solar glass increased the opportunity, it can convert light energy into electrical energy, solar energy equipment, without the need to color glass. The company from the Massachusetts institute of technology ( 麻省理工学院) Independent. Companies use organic dyes in the glass, the infrared spectrum of absorption of solar radiation, and convert it into electricity.

universal energy company ( 无处不在的能量) The chief technology officer myers & middot; Barr ( 英里巴尔) Last month, says & other; Light-absorbing dye is ubiquitous, exists in paint paint and clothes, even including electronic equipment. What we do is to make use of these dyes selectively absorb infrared light, infrared light into electrical energy. ”

the beauty of this kind of glass is that it is not just limited to the building, also can be installed in cars and even smart phone screen. The disadvantage is that the light-absorbing dye conversion is still relatively low. From another perspective, however, the efficiency of breaking the record, the highest. Last year, the universal energy company on the transparent solar cell conversion efficiency set a world record, 9. 8%.

with the development of renewable energy, the combination of low cost and easy extensibility will become more attractive, state of California is compulsory for each new family to use some form of solar energy technology.

the solar glass near-term outlook is unclear. The solar industry is not immune to the impact of the outbreak of coronavirus. Not surprisingly, the American solar industry leader & ndash; — California's pv new capacity also fell sharply. Many other industry situation is also similar. Due to shutdown caused unemployment to soar, solar power network, people have to cut spending.

according to the forecast, this year against any renewable energy. The industry jobs are lost, or will affect 250000 people. Meanwhile, many public projects may be delayed until the second half of 2020 and even next year.

but, for the solar industry, especially for those who offer cheaper than rooftop solar equipment industry, the outbreak may be only a temporary setback. Solar glass is carrying a lot of hope, solar equipment, implement the wish is only a matter of time.
