WebWe demonstrate the construction of an efficient bilayer polymer solar cell comprising of Poly(3-hexylthiophene) (P3HT) as a p-type semiconductor and asymmetric fullerene (C 70) as n-type counterparts.The bilayer configuration was very efficient compared to the individual layer perfornance and it behaved like a regular p-n junction device. WebJun 15, 2024 · Therefore, owing to the high elastic moduli of polymeric materials, polymeric SEI layers are being developed to protect Li metal anode and sustain volumetric changes during Li plating and stripping [ 24, 59, 66, 67 ]. However, the polymeric layers generally render inferior mechanical strength and ionic conductivity.
WebA polymer coating is a thin layered coating or paint made with polymers that provide superior adherence and protection from corrosion. A polymer is a molecule made by joining together many small molecules called monomers that are made up of a large number of similar units. This can include synthetic organic materials like resins and plastics.
