Graphene Oxide as an Auxiliary UV Photoprotector for Polypropylene
Auxiliary UV Protection. ABSTRACT This work presents the preparation and characterization of polypropylene (PP)/graphene oxide (GO) nanocomposites by adding photostabilizing additives to obtain materials with enhanced resistance to photodegradation. The synthesized GO (modified Hummers' method) was characterized using state‐of‐the‐art techniques.

Co‐Sensitized Solar Cell Achieves 13.7% Efficiency with Bis‐Hexylthiophene Dyes
The authors demonstrate that the longer excited state lifetime dye in combination with a copper electrolyte produces a high photovoltage of 1.22 V, owing to retarded interfacial charge recombination. The co‐sensitized solar cell achieves efficiencies of 13.7% under full sunlight and 29.7% under LED light.
