Spray-Deposition Perovskite Solar Cells Show 11% Efficiency

Posted on Tue, Jul 15, 2014 by Jack Stephenson

Alex Barrows and co-workers have reported the first demonstration of perovskite solar cells prepared via spray coating of the light-harvesting layer.

Using the perovskite CH3NH3PbI3-xClx, solar cells with a power conversion efficiency of up to 11% have been realised. Their devices incorporated a number of Ossila products, including Pre-Patterned ITO Substrates, PCBM, PEDOT:PSS and Encapsulation Epoxy, demonstrating product compatibility with this exciting and rapidly developing PV field.

Their paper, Efficient planar heterojunction mixed-halide perovskite solar cells deposited via spray-deposition, states "This study advances upon existing work where the perovskite layer has been deposited from solution using laboratory scale techniques such as spin-coating, and represents a significant step in the development of efficient, low-cost solar cell devices made using roll-to-roll compatible processing methods."

The paper has been published in the latest issue of Energy & Environmental Science.
