PPT-METAL OXIDES: PAVING THE WAY TO PEROVSKITE CELLS

Desmond Zheng Patrick Flaherty A Future with Perovskite Usage of fossil fuels is going to decline around the globe in the near future New perovskite solar cell technology possesses staggering efficiency and affordable cost. oxides are very efficient as mesoporous media for advanced catalysis . Natural halloysite clay nanotubes available in large quantities at low price are very promising for this purpose .
