PEROVSKITE CELLS PERCOLATES : SCIENCE PRECIS

 

Will Perovskite Solar Cells Take off? : Most photovoltaic cells are made of silicone and convert sunlight to electricity with an efficiency of about 23%.

Perovskite cells, which use other elements in a particular crystal structure, cost more but offer higher efficiency : over 25%.

And offer over 30% when combined in a ''tandem'' cell with silicon.

So the extra expense can be worth it, particularly in situations where space is tight.

Firms in America, Britain, South Korea and Sweden aim to start selling perovskite cells in 2024.
