Chinese researchers have taken what they say is a major step forward for the development of a new generation of solar cells. Manufacturers have long used silicon to make solar panels because the material was the most efficient at converting sunlight into electricity. But organic photovoltaics, made from carbon and plastic, promise a cheaper way of generating electricity. This new study shows that organics can now be just as efficient as silicon. Organic photovoltaics (OPV) can be made of compounds that are dissolved in ink so they can be printed on thin rolls of plastic, they can bend or curve around structures or even be incorporated into clothing. Commercial solar photovoltaics usually covert 15-22% of sunlight, with a world record for a silicon cell of 27.3% reached in this summer in the UK. Organics have long lingered at around half this rate. In April researchers were able to reach 15% in tests. Now this new study pushes that beyond 17% with the authors saying that up to 25% is possible. This is important because according to estimates, with a 15% efficiency and a 20 year lifetime, organic solar cells could produce electricity at a cost of less than 7 cents per kilowatt-hour. In 2017, the average cost of electricity in the US was 10.5 cents per kilowatt-hour. Flexible, printed solar cells offer a wide range of possibilities. They can work indoors and they can be made semi-transparent, so they could be incorporated into windows and generate power during daylight.

One single-use plastic bag takes at least 450 years to degrade. Give Miranda Wang three hours and she can reduce ten of them into liquid. Recycling plastic today is a mechanical process ... limited to only certain types of plastics: PET, used in water bottles, and HDPE, used in milk jugs. The five other types of commonly used plastics ... cannot be recycled. Adding to this is that most plastics thrown away are covered in food and grease and so are automatically rejected by markets with strict quality standards. These are the plastics Wang has her sights on. “Our technology can turn these dirty films that have food or dirt or any kind of grime or any kind of contamination on it and we turn this material into a combination of four different kinds of chemicals, called organic acids,” says Wang. One of these chemicals is adipic acid, a precursor for materials like nylon and polyamines used in fashion, for electronic parts and in the automotive industry for car parts. “Our vision is to transform a polyethylene, which right now does not have any downstream market value once its consumed and is used for one life cycle, and we turn it into a chemical that is of the same quality as what is immediately made from petroleum - adipic acid,” says Wang. “This first helps us not allow film plastics from becoming pollution and second ... displaces petroleum from being needed to be extracted to make new materials.”
