New type of solar panels created

Создан новый тип солнечных панелей (3 фото) Currently, solar panels are either organic or silicon. Organic have flexibility and transparency, and silicon panels, although more effective, these properties are absent. The research team at the Massachusetts Institute of Technology has set itself the task of developing solar panels that are both flexible and transparent, and at the same time, quite effective. which has a thickness of only one atom. Thanks to this, he conducts electricity perfectly. However, it was still necessary to solve the problem of how to adhere the electrodes directly to the substrate. If graphene is attached by gluing or heating, it can be damaged, which will lead to a decrease in conductivity. Создан новый тип солнечных панелей (3 фото) MIT scientists found an original solution: they developed a technique that allows graphene to be fixed by spraying ethylene-vinyl acetate onto its top layer, which gives the same effect as the glue layer. So the problem with the electrodes was solved. According to Yi Song, one of the developers of the project, in this case both the upper and lower electrodes will be able to fully perform the functions of the electron flow. Создан новый тип солнечных панелей (3 фото) When the first sample of the new solar cell was received, tests were conducted to compare its efficiency with those materials that are commonly used in solar panels: aluminum, indium tin oxide, standard materials on various substrates, glass (rigid) and flexible. Testing showed that the conversion efficiency was 4.1%. True, this result is worse than modern panels demonstrate, but it exceeds the efficiency of transparent panels. According to the calculations of researchers, solar panels with graphene are able to, without losing transparency, become 10% more efficient, but if this value is exceeded, transparency will fall. What is the cost of a potential solar panel made of new material and its durability with wear resistance is not specified.
