Printable Solar Cells Shed Light On New Opportunities

Researchers from a university in Finland have found that solar cells can now be colorful and patterned using an inkjet printer.

According to Aalto University, a new kind of solar cell has been developed which uses photovoltaic dye during the inkjet printing process.

The photovoltaic dye can be printed into any shape during the printing process.

Then the solar cell can be installed on a low-powered electrical device, and could be part of its visual design. At the same time the cell can produce energy for its needs.

According to the researchers, the inkjet-dyed solar cells are different from traditional solar cells, and can endure for more than one thousand hours of continuous light and heat stress without compromising performance.

The best dye and electrolyte obtained so far is from the research group in the Swiss École Polytechnique Fédérale de Lausanne. It is said that suitable solvents for the dye and right printing parameters are still the biggest challenge for precise and uniform print.

As revealed, this new research also sheds “new light” on the development of decorative products and building integrated solar cells.
