A chemical treatment using DSH prevents light-induced degradation in mixed halide perovskites, paving the way for more stable solar cells and LEDs.

First experimental demonstration of a 4T- silicon-perovskite tandem solarcell from India, with efficiency greater than 26%.

Although Solar energy has been often hailed as a green source of energy, shortcomings in conventional silicon based solar cells and the environmental damage caused during mining and manufacturing of such cells raises questions on the green nature of the energy. In a breakthrough, scientists have developed organic solar cells, developed from indigenously developed discotic liquid crystal, that could provide an alternative.
