A novel avenue to high-performance, stable perovskite solar cells

GOTSolar's EPFL researchers from Michael Grätzel's lab show how stable, scalable, and efficient perovskite solar cells can be produced through molecular engineering of multifunctional molecular modulators and using solid-state nuclear magnetic resonance to investigate their role in double-cation pure-iodide perovskites.

New film about our project!

The goals of GOTSolar and ways we are on to achieve them have now been described in a short movie. Grant executors from UPORTO and EFACEC tell the story behind their involvement in perovskite photovoltaics.


Power of mechanochemistry: A new multicomponent perovskite

Scientists working within GOTSolar have demonstrated a perovskite cell, in which a relatively large guanidinium cation was incorporated into the crystal structure of perovskite using solventless mechanochemical approach. Guanidinium perovskites contain less volatile amines and are more resistant to external factors than the parent perovskite. The higher durability of the photovoltaic cells is a considerable argument in favour of their commercialization.

JPH2018 – an event supported by GOTSolar

For a third year in a row, the GOTSolar consortium, supports the French Workshop on Hybrid Perovskites. The JPH2018 took place 14-16th May 2018 in Grenoble-Autrans in the French Alps.

ABXPV Perovskite Thin Film Photovoltaics 2018: Summary and Pictures

27-28 February 2017, the GOTSolar consortium co-chaired a symposium devoted to recent progress in perovskite solar cells. The chairperson of the conference from GOTSolar was Jacky Even (CNRS/INSA Rennes), and the organisation work has been performed by NanoGe. The event was hosted in Rennes, France. The ABXPV18 attracted ca. 200 participants from all over the world.

Scientific information and profile of the conference can be found here:
