Milestone Payment

Nanoco Group plc (AIM: NANO), a world leader in the development and manufacture of quantum dots, solar inks and other nanomaterials, announces that it has achieved a key milestone in its solar photovoltaic agreement with Tokyo Electron, a major Japanese semiconductor production equipment supplier, triggering a payment.

The milestone was triggered after Nanoco successfully developed and supplied a bespoke solar ink, which has been used to create a nanomaterial thin film for the production of solar cells.

The next step in the nine-month development phase of the agreement, which was signed in June 2010, is to continue to improve solar power efficiency.

Michael Edelman, Nanoco's Chief Executive Officer, said: "This milestone in our agreement with Tokyo Electron represents another major step for Nanoco and is further endorsement of the potential of our technology in the solar power sector."
