Are you tired of the same old-fashion online conferences? Join us at International Solar Power Technologies (SPTech) Conference and get ready for experiencing the next generation of online conferences! Science, networking, discussion, ePoster game, awards and many more.

You are invited to join us from 5 to 8 July 2021 for the first online edition of SPTech conference hosted by University of Porto, Free of charge for all participants.

Organized by Faculty of Engineering - University of Porto in partnership with LEPABE, Dyenamo and Pixel Voltaic. The 2021 online conference will gather leading solar energy researchers from around the world. The 4 days event will bring together experienced scientists and talented researchers to discuss the current status of:
  • Solar Fuels and Storage Technologies;
  • Dye-Sensitized Solar Cells;
  • Perovskite Solar Cells.
We are pleased to introduce, for the first time, the ePoster game (watch the demo on YouTube
