At this year’s EU PVSEC from 7 to 11 September 2020, scientists from ISFH will give a total of eight oral presentations – one of them in the plenary – and present four posters. Due to the current situation, the EU PVSEC will take place completely online, but with all the basic features that a physical event is recognisable for: Live presentations in all cases (Plenary, Oral and Visual) and the possibility of live interaction between presenters and audience (questions, debate) via face to face tools and Q&A chat.
On Monday afternoon, Dr. Dominic Walter will report on the disappearance of hydrogen-boron pairs in silicon (2AO.5.1). In the following session, both Dr. Felix Haase and Dr. Byungsul Min will present the development progress of solar cells with a POLO and an aluminum contact. At ISFH, this combination is used for both back-contact solar cells (2AO.6.2) and double-sided contact solar cells (2AO.6.4).
Lasse David is also working on POLO contacts. On Tuesday morning he will show his results on sputtered and in-situ phosphorus-doped poly-Si layers (2BO.1.3). Before lunch, Philip Jäger will explain his advanced chemical model for the diffusion mechanism of phosphorus during POCl3 diffusion (2BO.2.6).
On Wednesday morning Matthias Littwin will present the results of the IEA PVPS Task 13 Subtask 1.3 – Performance of New Photovoltaic System Designs (CP.1.5) in the second plenary of the EU PVSEC. In the afternoon Dr. Karsten Bothe explains how busbarless solar cells are contacted for accurate current-voltage measurements (2CO.15.2).
On Thursday before the lunch break, Timo Gewohn will describe the CoTex method developed by him, with which the appearance of PV modules can be customized (6DO.12.3).
Also on Wednesday and Thursday four posters will be presented by ISFH researchers. Timo Gewohn will show the outdoor test facility for the experimental validation of yield predictions for building-integrated photovoltaic modules (6CV.2.16). Michael Winter informs about the light-induced degradation of lifetime in Cz-Si wafers triggered by a firing step (2DV.2.15).
Dr. Sören Schäfer explains how laser-induced oxidation of doped poly-Si at room temperature can be used for Si solar cells with structured, passivated contacts (2DV.3.5), while Maximilian Stöhr uses PECVD shadow mask deposition of a-Si fingers to pursue a shortcut to structured poly-Si for local passivating contacts (2DV.3.21).

The EuroSun 2020 – 13th International Conference on Solar Energy for Buildings and Industry will take place from 1 to 3 September 2020 – this year as a fully virtual conference. See the EuroSun 2020 website for the full conference programme. Researchers from ISFH will give a total of six presentations:
On Tuesday morning, Elisabeth Schneider will discuss Renewable-Energy-Driven Heat Pumps for Districts to Reduce Primary Energy Demand in Session Oral Presentations 2: Solar Assisted District Heating and Cooling. In the parallel Session Oral Presentations 3: PV and PVT Systems for Buildings and Industry, Bharat Chhugani presents his Model Validation and Performance Assessment of a Novel Unglazed Photovoltaic-Thermal Collector with Heat Pump Systems.
In Tuesday’s poster session, Dr. Federico Giovannetti will demonstrate Solar Steel Sandwich Panels for Industrial and Commercial Buildings: System Simulations and Potential Analysis.
During Wednesday’s poster session, Bert Schiebler will describe his Experimental Evaluation of Stagnation-Safe Flat Plate Collectors with Heat Pipes for Domestic Hot Water Preparation in Thermosiphon Systems.
Peter Pärisch will illustrate a Parameter Study of Four Different Instantaneous Water Heaters in a Solar Assisted Multi-Family House with TRNSYS on Thrusday morning in Oral Presentations 14: Domestic Hot Water and Space Heating.
In the final poster session on Thursday, Fabian Hüsing explains his Modelling of Inverter Heat Pumps in TRNSYS.

Dr. Felix Haase will give a presentation on Tuesday, June 9, 2020, at 14:00 CET on the topic “What’s behind the high potential of passivated contact solar cells”.
The talk is part of an online seminar by TaiyangNews on the latest developments of TOPCon solar cell technology, which uses passivated contacts. In addition to the talk by Dr. Felix Haase, TaiyangNews will give an overview of the latest developments in the field of high-efficiency solar cells and Jolywood will update on their work and projects with this technology.
The participation in the online seminar is free of charge. Further information can be found here: http://taiyangnews.info/webinars/jun-9-potential-and-recent-developments-of-high-efficiency-n-type-passivated-contact-topcon-solar-cell-technologies/
