Reuters News Recently, British scientists said that plastic solar cells can be commercialized in the next 10 years. On Monday, the research team announced new discoveries for replacing crystalline silicon solar panels and producing cheaper batteries.
Governments have successively launched stimulus plans to use low-carbon energy instead of fossil fuels. Thanks to this, the global installed capacity of solar energy has been rapidly developed.
Due to the relatively slow solar power generation in the past, the overall base was low. Even after rapid growth in recent years, it accounts for only 1% to 2% of the world's total electricity generation.
Most current solar panels are made of ultra-high-purity silicon wafers. The advantage of plastic solar panels is that they can be manufactured faster and cheaper by printing and coating processes.
A team of researchers from the University of Sheffield, University of Cambridge and Other research institutes stated that they have a deeper understanding of the production process of plastic solar cells. In addition, there are some research institutions that are studying the conversion rate of plastic batteries.
Richard Jones, a professor at the University of Sheffield, said: "I think that in the next 5 to 10 years, this type of battery will be able to achieve large-scale production." The remaining problem is to design a longer-lived power generation. system.
At present, there is a printing process that can realize solar panels with a size of several football fields printed once.
Researchers have demonstrated how two different photoactive materials can enter the laminate of positive and negative conductors to form an electrical current, and plastic thin-film solar phones are still being set up.
Jones said: "We have confirmed in a special system that the positive and negative electrons in the plastic film battery are flowing in the correct direction."
The advantage of this process is that it can be carried out at very low temperatures, which is why we are able to use plastic films and printing presses. The current manufacturing of crystalline silicon solar cells needs to be performed under very high temperature conditions, depositing silicon on a very hard material such as glass and Metal Products.
