Title of talk: Tissue Engineered Heart Repair - ready for translation?
Speaker's name: Dr. Malte Tiburcy
Speaker's organisation: Institute of Pharmacology and Toxicology at the University Medical Center Goettingen, Germany
Talk abstract: Heart failure is a growing health problem with limited therapeutic strategies. The progressive nature of heart failure can be slowed down by pharmacological interventions but this cannot prevent a continuous loss of functional heart muscle. Recent developments in human pluripotent stem cell biology have encouraged researchers to envision true remuscularization of the diseased heart. While several approaches are being investigated to achieve meaningful remuscularization our group focusses on validating and translating tissue engineered human myocardium for cardiac repair. Functional human heart muscle can be generated at relevant size and defined quality to allow a cGMP compatible production. Proof on principle studies in animals demonstrate feasibility of the approach but need to be further refined to demonstrate safety and efficacy of tissue engineered heart repair.

Other Details: Following the seminar, refreshments in the form of beer and pizza will be available as usual.

Title of talk: Metal halide perovskites: a new family of semiconductors for photovoltaics and optoelectronics
Speaker's name: Prof. Henry J. Snaith
Speaker's organisation: University of Oxford
Talk abstract: Over the last few years metal halide perovskites have risen to become a very promising PV material, captivating the research community. In the most efficient devices, which now exceed 22% solar to electrical power conversion efficiency, the perovskite is present as a solid absorber layer sandwiched between n and p-type charge collection contacts. Increasing importance of improving solar cell operation is reliant upon understanding and controlling thin-film crystallisation and controlling the nature of the heterojunctions between the perovskite with the p and n-type charge extraction layers. In addition, understanding and enhancing long term stability of the materials and devices if a key driver. Despite the competitive efficiency, and assuming that stability challenges will be surmountable, for perovskites to feasibly enter the PV market, the commercial modules need to deliver something which other technologies cannot: Their unique selling point is ease of tuning the band gap, which can deliver both hybrid and all-perovskite multi-junction solar cells, with a feasibility of much higher efficiency than current commercial flat plate PV technologies. I will present the brief recent history of the emergence of perovskite photovoltaics, and highlight the key factors which are important for reaching the maximum efficiencies. I will specifically highlight recent advances in understanding the thin film crystallisation and enhancing the long term operational stability through compositional design of the perovskite, in addition to appropriate choice and adaptation of charge selective contacts. I will demonstrate efficient perovskite solar cells with band gaps ranging from 1.2 to 1.8 eV and show these materials integrated into hybrid tandem solar cells with silicon and all perovskite monolithic 2-terminal tandem cells. I will discuss some new prospects for novel perovskite-like semiconductors beyond lead-halides, and present expanding activity in perovskites for light emitting applications.
