With the continual increase in demand for global energy, scientists across the world are working to find a way to transition from fossil fuels to renewable energy sources that are more efficient and environmentally friendly. The sun delivers more energy to the Earth’s surface in one hour than the entire world uses in one year, and realizing the full potential of solar power will require finding effective, inexpensive ways to utilize this vast energy source.

A new paper published in the Journal of the American Chemical Society has identified a possible inorganic material for perovskite solar cells, which provides a lower-cost alternative to the organic polymers currently used in the cells.
