1. TandemPV Workshop, hybrid (30/5-1/6)
“Perovskite/CuInSe2 Tandem Solar Cells” by Erik Ahlswede (ZSW), who will give an overview of 2-terminal device development within the PERCISTAND project. Efficiencies above 23.5 % will be presented.
“Optimization of Semitransparent Perovskite Solar Cells for Use in Tandem Stacks” by Erik Ahlswede (ZSW). A report on semitransparent perovskite solar cells with a bandgap of 1.62 eV optimized for the use in tandem devices based on p-i-n configuration with multi-cation double halide perovskite absorber layers.
“On the Chemical Robustness of Commercial Stainless-steel Foil Substrates for Chalcogenide-based Absorber Layers” by Sarallah Hamtaei (imec). This is an evaluation on chemical stability of flexible stainless-steel substrates in response to a typical 2-step processing of CI(G)S absorbers.
“A Perovskite-based Tandem Solar Cells Database: Predicting Guidelines from Recent Publication Trends” and “Monolithic 2-Terminal Perovskite/CuInSe2 Tandem Solar Cells with Efficiency Approaching 25%”, by Marco A. Ruiz-Preciado (KIT).
“Stable Architectures and Scalable Processes for Semi-transparent Modules and Tandem Top Cells” by Anurag Krishna (imec). This presentation will focus on stable architectures and scalable processes for efficient semi-transparent modules and tandem top cells.
2. EMRS Spring Meeting, virtual (30/5-3/6)
At symposium K on thin film chalcogenide photovoltaic materials, in the Tandems & wide bandgap CIGSe session:
“Design and Optimization of Perovskite / CI(G)S Tandem Solar Cells” by Philip Schulz (CNRS-IPVF). In his invited presentation Philip will discuss the development of monolithic two-terminal perovskite / CI(G)S tandem solar cells. Special focus of the talk will be on the analysis of the chemistry and optoelectronic properties at the interfaces in the device stack.
“Impact of Ag on the electronic transport in low bandgap CuInSe2 solar cells” by Maximilian Krause (EMPA). Low bandgap CuInSe2 thin-film solar cells are usually limited by an unfavorable buffer-absorber band alignment, hence the impact of Ag-alloying on the formation of ordered-vacancy compounds - such as the Cu-poor phase CuIn3Se5 - is investigated.
