Indian scientists have devised a new process for increasing the efficiency and stability of Titanium dioxide (TiO2) nanorods based on Perovskite Solar Cells (PSC). 

Perovskite solar cells 

• Perovskites are a family of materials with a specific crystal structure, named after the mineral with that structure. 
• When used to create solar cells, they have shown potential for high performance and low production costs. 

 Nanorods

• Nanorods are one-dimensional structures that provide a directed path for electrical transport.
• They are used to control the band gap by varying the radius of rods and using the quantum size effect. 
• Nanorods are nanostructures that are the object of fundamental and applied research.
• They may be prepared from carbon, gold, zinc oxide, and many other materials.
