Energy breakthrough as solar power world record smashed thanks to ‘miracle material’

To solve this issue, researchers like the team of HZB are looking to alternate them with other materials inside a cell, in an effort to increase their lifespan. These are called tandem solar cells, and experts believe that they could soon prove commercially viable.

While the top cell can utilise blue light components, the bottom cell converts the red and near-infrared components of the spectrum. Different thin layers help to optimally utilise the light and minimise electrical losses. 

Due to technological advancements, the sunlight-to-energy efficiency of a solar cell has jumped nearly tenfold from 3.8 percent a decade ago to the current record of 32.5 percent.

Following a previous solar cell efficiency record, Z. Valy Vardeny from the University of Utah hailed perovskite, saying: “It’s unbelievable, a miracle material.”
