What is the News?
Indian Scientists have devised a new process for increasing the efficiency and stability of Titanium dioxide (TiO2) nanorods based on Perovskite Solar Cells (PSC).
What are Perovskite Solar Cells(PSC)?
Perovskite Solar Cells(PSC) is a type of solar cell that includes a perovskite-structured compound, most commonly a hybrid organic-inorganic lead or tin halide-based material, as the light-harvesting active layer.
PSCs have become commercially attractive because of the potential of achieving even higher efficiencies and very low production costs. However, the challenge lies in its short- and long-term stability.

What have the scientists done?
Scientists have increased the efficiency and stability of Titanium dioxide (TiO2) nanorods based on Perovskite Solar Cells(PSC) by varying the length and porosity of the TiO2-Nanorods. This will help to develop solar cells with stable light-harvesting active layers.
