Organic Solar Cells from Papaya

Mar-12-20 Titania (titanium dioxide) thin films which are used in solar cells require high temperatures to fabricate as well as expensive high-end technologies, but researchers have now developed a fully organic method to engineer titania at low temperatures.

Using papain, an enzyme found in papaya fruit, researchers have created a simple dip-coating procedure, that also allows up to 50 titania layers to be stacked, unlike current methods.

The porous nature of the film allows access to a large surface area that engineers believe will result in higher solar cell efficiencies and lower production costs.
