X-Ray analysis towards highly stable, superior efficiency perovskite solar cells — •Shambhavi Pratap, Johannes Schlipf, and Peter Müller-Buschbaum — TU München, Physik-Department, LS Funktionelle Materialien, 85748 Garching, Germany

Perovskite solar cells represent the new wave in the field of photovoltaics and show a lot of promise. The technology has seen a meteoric rise with device performances crossing the 20% mark in just half a decade since its' inception.

The major challenge in the field remains the stability of these cells. The science of the response of the perovskite materials to atmospheric conditions of moisture and temperature demands considerable investigation before commercialization of these cells is feasible.

We aim to understand the structural changes occurring in the material with controlled humidity and temperature conditions, and to enhance the stability by the addition of functional additives and the use of novel solvent media during the synthesis of the perovskite crystals.

Grazing-incidence wide angle X-ray scattering (GIWAXS) aids us to understand the stability of the perovskite structure of the material and help us to gain insight for the fabrication of high-efficiency, long term stable perovskite solar cells.
