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... Continue

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... Continue

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 limit... Continue

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 ... Continue

The session ist 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 p... Continue

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 polymers. Wi... Continue

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 donor/a... Continue

After Prof. Jen's inspiring talk on materials design (see previous post) Prof. Morten Madsen from the Mads Clausen Institute at the University of Southern Denmark gave a great review on stability of organic solar cells by detailing various aging mechanisms of all layers in OPV. Surprising results p... Continue

The second tutorial session of the NGSE5 was started out by Prof. Alex K.-Y. Jen from the City University of Hongkong. Prof. Jen is a pioneer in the design of Donor-Acceptor Molecules which helped pushing OPV efficiencies in the past few years. In his tutorial he gave an introduction into material... Continue

The NGSE5 was kicked off today with a short greeting by Prof. Brabec. The first day featured two great Tutorials. With an average of ca. 210 participants this was the best attended NGSE so far. Opening-slide NGSE5 Opening of the NGSE5 The first Tutorial was held by Prof. Uwe Rau (Forschung... Continue
