Global Solar PV Brain Trust
The Global Solar PV Brain Trust is a loose association of experts committed to the future of solar power worldwide. It is a non-profit group supported by the Reiner Lemoine Foundation in Berlin, Germany.
The Foundation was established by Reiner Lemoine shortly before his death in 2006. Reiner was one of the leading figures in Germany’s early development of solar PV technology. He was born in 1949, studied aerospace engineering in Berlin and went on to found several companies in the solar sector, including Solon in 1996 and Q‑Cells in 1999. The Foundation awards scholarships to doctoral students who wish to study renewable energy technologies.

As part of its work, the Foundation funds a range of projects on the energy transition, including the German-language group, the “PV — Think Tank”, as well as the work of the Global Solar PV Brain Trust.
