Up to 2023, solar power has surpassed coal as the energy production technology with the quickest rate of growth.

According to recent statistics, solar and wind power have grown at an unprecedented rate, making them the fastest-growing electricity producing technology in history.

95% of solar panels are made of silicon, which must be heated to temperatures exceeding 900°C to get the high purity required to produce high-efficiency cells.

Because it is easier to manufacture and makes better use of more of the solar spectrum than silicon, perovskite is a viable substitute for silicon in light-absorbing applications.

A novel formamidinium lead iodide (FAPbI3) crystal developed by Rice University is helping to improve the stability of perovskite solar cells. After 1,000 hours at 85°C, the crystal only loses 3% of its efficiency.
