On October 19, 2018 Golnaz Sherafatipour defended her thesis in Sønderborg.
At the moment Golnaz is a visiting researcher at IMEC in Belgium.
Over the past three decades, tremendous amount of research has been devoted to the field of renewable energy in order to reduce our dependence on fossil fuels. Among them, organic (OSC) and perovskite (PSC) solar cells have gained enormous attention as they offer unique advantages compared to the traditional silicon solar cells, such as low fabrication cost, mechanical flexibility, light-‐weight modules and semi-‐transparency. These unique properties offer a wide range of applications and integration schemes, which make this field of research even more exciting. OSC and PSC
have recently achieved power conversion efficiencies (PCE) of around 15% and 22%, respectively, emphasizing the great
potential of the technologies. However, both of these devices suffer from low stability and short lifetime (degradation).
Therefore, understanding the degradation mechanisms of these devices, paves the way for viable commercialization of
this appealing technology in the market.
This work is dedicated to investigate governing degradation mechanisms and pathways taking place inside organic and perovskite solar cell devices. First part of the work focuses on the performance and stability of DBP-‐C70 based organic solar cells in standard and inverted device configurations. We study their device stabilities by aging them under ISOS-‐D-‐3 (darkness, 85℃ and 85% RH-‐humidity) and ISOS-‐T-‐3 (darkness,-‐40℃ and room humidity) conditions. The
results show that despite a change in the performance upon aging, there is a pronounced morphological stability at the
DBP-‐C70 interface. Possible effects from the electron transport layer (ETL) on the device stability were investigated, demonstrating that this layer contributes significantly to the degradation of the inverted devices.
The second part of this work focuses on understanding the degradation mechanisms taking place inside perovskite solar
cells under real operational conditions. Results for indoor (ISOS-‐L-‐1, illumination, 60 ℃ and ambient humidity) and outdoor (ISOS-‐O-‐1,sunlight, ambient) degradation test conditions are conducted, showing reversible and irreversible degradation mechanisms under light-‐darkness cycles, which reveal interesting degradation pathways and emphasize on
the importance of including these cycles in experimental protocols for the assessment of long-‐term stability of the PSCs.
On June 27, 2018 Shashank Harivyasi will defend his Thesis in Graz.
On 2. February Mina defended her thesis in Sønderborg and on 21. February Miles defended his thesis in Milan. Congratulations to both of you!
You can find Minas thesis under ‘Projects’ and Miles will follow shortly. Mina found a job in industry as an application engineer.

Paola Pellacani handed in her Thesis to be evaluated by a committee of the Iberian Vacuum Conference RIVA-X, Bilbao, October, 2017. She won the “Best Thesis” award, sponsored by Leybold. The prize gave her the opportunity to give an invited talk and get some of her expenses covered.
A great honor to Paola, congratulations!
with Mato Knez as Editor-in-Chief, Vida Engmann, Morten Madsen and Horst-Günter Rubahn editors, to appear in ‘World Scientific Publishing’
The book focuses on the use of various organic and hybrid materials for developing new devices, and includes many different aspects of device technology, from materials development to device fabrication and integration of reliable devices. In order to realize the 14 different chapters focusing on these areas, world leading experts on devices from hybrid and organic materials are put together to form a comprehensive book suited for new readers as well as those more experienced in this field.
Expected to appear early 2018.
