Guidelines for Material Design in Semitransparent Organic Solar Cells
Karen Forberich, Alessandro Troisi, Chao Liu +3
Organic solar cells (OSCs) are uniquely suited for semitransparent applications due to their adjustable absorption spectrum. However, most high-performance semitransparent cells re…
Matching the photocurrent of perovskite/organic tandem solar modules by varying the cell width
Jose Garcia Cerrillo, Andreas Distler, Fabio Matteocci +12
Photocurrent matching in conventional monolithic tandem solar cells is achieved by choosing semiconductors with complementary absorption spectra and by carefully adjusting the opti…
A Digital Twin to overcome long-time challenges in Photovoltaics
Larry Lüer, Marius Peters, Ana Sunčana Smith +9
The recent successes of emerging photovoltaics (PV) such as organic and perovskite solar cells are largely driven by innovations in material science. However, closing the gap to co…
Traps and transport resistance: the next frontier for stable state-of-the-art non-fullerene acceptor solar cells
Christopher Wöpke, Clemens Göhler, Maria Saladina +17
Stability is one of the most important challenges facing organic solar cells (OSC) on their path to commercialization. In the high-performance material system PM6:Y6 studied here,…
The Evolution of Materials Acceleration Platforms -- Towards the Laboratory of the Future with AMANDA
Jerrit Wagner, Christian G. Berger, Xiaoyan Du +3
The development of complex functional materials poses a multi-objective optimization problem in a large multidimensional parameter space. Solving it requires reproducible, user ind…
Analytical Model for Light Modulating Impedance Spectroscopy (LIMIS) in All-Solid-State p-n Junction Solar Cells at Open-Circuit
Osbel Almora, Daniel Miravet, Gebhard J. Matt +2
Non-circuit theory drift-diffusion numerical simulation of standard potentiostatic impedance spectroscopy (IS) is a well-known strategy for characterization of materials and electr…
Spin-split bands cause the indirect band gap of (CHNH)PbI: Experimental evidence from circular photogalvanic effect
Daniel Niesner, Martin Hauck, Shreetu Shrestha +7
Long carrier lifetimes and diffusion lengths form the basis for the successful application of the organic-inorganic perovskite (CHNH)PbI in solar cells and lasers. The…
Temperature-dependent optical spectra of single-crystal (CHNH)PbBr cleaved in ultrahigh vacuum
Daniel Niesner, Oskar Schuster, Max Wilhelm +6
We measure temperature-dependent one-photon and two-photon induced photoluminescence from (CH3NH3)PbBr3 single crystals cleaved in ultrahigh vacuum. An approach is presented to ext…
