Henrik Lindström and Giovanni Fili

Our favorite Piñatex did not win. But we are happy to announce that Exeger Operations AB (Sweden) has won in the category SMEs, with their invention of 

An efficient, affordable and versatile solar cell film developed by Swedish innovators Henrik Lindström and Giovanni Fili is being used to power everyday self-charging electronic devices such as bicycle lights. Lindström, a chemist and technical scientist, and Fili, an entrepreneur, combined their complementary skills to pioneer the production of this innovative printed material and successfully bring their invention to market. 

Flexible solar energy harvesting & storage solutions

Bonar, Centexbel and partners have developed a similar invention a few year ago, in the form of a wire shaped coaxial photovoltaic solar cell.

The patent application for this invention can be consulted in the Espacenet database.

Solar wire

A wire shaped coaxial photovoltaic solar cell comprising: a conductive core wire shaped support (401), a nanostructured semiconductor scaffold layer (402), one or more successive perovskite layers (403), an optionally provided hole transporting material layer (404), an outer conductor layer (405), an outer protective layer (406), characterized in that said outer conductor layer (405) comprises dispersed nanoparticles and said perovskite layers (403) are composed identically or wherein two or more of said layers have a different molecular structure and/or composition. The invention also relates to methods and apparatus for the fabrication of said wire shaped coaxial photovoltaic solar cell.
