The International Symposium on Singlet Fission and Photon Fusion: Emerging Solar Energy Conversion Technologies (ISPF²) is the major forum for discussion and dissemination of new results on all topics concerning the photon managing processes. The first two events were organized in Gothenburg by Maria Abrahamsson, Kasper Moth Poulsen, and Bo Albisson. After the success of the 2016 and 2018 ISPF² conferences, we were forced to cancel the 2020 edition due to the Covid emergency. Now, it is our great pleasure to invite you to the 3^rd edition of this meeting, held at Milano-Bicocca University, 10^th-13^th October, 2022.

The symposium is focused on the rapidly growing fields of photo-physics and materials science and will cover all aspects of:

• Singlet fission
• Photon fusion

During ISPF² you will meet with other world-class scientists to discuss and exchange ideas on the hottest topics and progress on the photon management.

Looking forward to seeing you in Italy.

Angelo Monguzzi & Franco Meinardi
