Yongfang extended the pi-conjugation of Y6 by inserting a double bond between the central core and end groups and pushed the optical bandgap to 1.21 eV (BTPV-4F). The single-junction devices based on this novel acceptor achieved a short-circuit current density of 28.9 mA cm−2, and provide ideal con...

Xiaoyan demonstrates the potential of our self-developed platform AMANDA Line One for fabricating and characterizing organic solar cells automatically in a high-throughput manner

Congratulations to Daniel for winning the national prize for the best post-grad thesis in chemical engineering in Colombia, which was awarded by the national council of chemical engineers. Daniel performed a significant part of his Master thesis in 2019 at i-MEET under the supervision of Thomas (Dr...

Osbel Almora Rodriguez introduces the concept of the “Emerging PV Initiative”. The goal of the initiative is to compile a database of research cell performance data that is accessible, interactive and up-to-date. The database is supposed to reflect the status of development of new technologies by p...

In the plenary Prof. McGehee reports on his progress in making metal halide perovskite solar cells stable. In his labs his group has been able to pass the industry standard ALT tests with Perovskites in a device architecture based on a layer stack of Perovskite/Fullerene/ALD SnO/Sputtered ITO. In h...

The first contribution in this session is from Maria Antonietta Loi, Professor of Photophysics and Optoelectronics at Groningen University with a talk on “Sn-based perovskites from hot electrons to device performances”. Hot electrons are an intriguing idea for exceeding the Shockley-Queisser l...

The fourth tutorial session at the NGSE4 was kicked off by Henri Snaith from the University of Oxford with a great introductory lecture. Prof. Snaith lectured on the basics and the development of Perovskite materials for PV-applications leading up to the design of Si/PSK-Tandem Solar cells, ending ...

The session is started out by Prof. David Mitzi from Duke University with a detailed review of the Perovskite structure, its properties and means of manipulating them by changing the composition and manufacturing methods. With his detailed investigations Prof. Mitzi shows the amazing spectrum of pr...

In the first talk of the second Hot Topics Session Prof. Zuo Xiao reviews the development of non-fullerene acceptors and polymer donors towards the current certified record OPV cells with efficiencies >18% in a single junction. For the donors the most promising materials are fused ring...

Hongbin Wun reports on loss mechanisms in high performance polymer solar cells, demonstrating the advances that have been made with modern non-fullerene acceptors and donor-acceptor molecules in his presentation titled “Assessing efficiency of photoinduced charge separation between electron do...
