Correlation of Band Bending and Ionic Losses in 1.68 eV Wide Band Gap Perovskite Solar Cells

Advanced Energy Materials, EarlyView.
Piperazinium salt treatments with different anions (chloride, iodide, tosylate, and bistriflimide) influence the energetics, carrier dynamics and long‐term stability of 1.68 eV perovskite solar cells. Chloride treatments achieve the highest efficiency (21.5%) but suffer from fast degradation due to ionic losses.

Construction of hybrid 1D‐0D networks for efficient and accurate blood flow simulations

International Journal for Numerical Methods in Fluids, Volume 95, Issue 2, Page 262-312, February 2023., 2023
A set of coupling equations to appropriately couple nonlinear 1D and lumped‐parameter (0D) models for blood flow in compliant vessels is defined. Then, a methodology for the high‐order numerical coupling between 1D and 0D vessels through hybrid junctions is proposed.

Transport Resistance Dominates the Fill Factor Losses in Record Organic Solar Cells

Advanced Energy Materials, EarlyView.
Organic photovoltaics are a promising solar cell technology, but even the record devices with 20% efficiency have significant fill factor losses due to low active layer conductivities. In this Perspective, the authors describe the origin of these losses, discuss experimental methods for their quantification, and explain how to minimize them to optimize

A deforming‐mesh finite‐element approach applied to the large‐translation and free‐surface scenario of fused deposition modeling

International Journal for Numerical Methods in Fluids, Volume 95, Issue 2, Page 334-351, February 2023., 2023
A boundary‐conforming free‐surface finite element method applied to fused deposition modeling (FDM) is presented. Using a boundary‐conforming approach shows to have several advantages in an FDM simulation. In particular, boundary conditions, like heat fluxes or free‐surface, can be directly imposed on the boundary.

Sustainable Thermal Solutions: Enhancing Heat Transfer with Turbulators and Nanofluids

Advanced Energy and Sustainability Research, EarlyView.
Nanofluids, which are nanoparticle suspensions in base fluid, facilitate heat transmission due to their improved thermal conductivity. Turbulators, which are inserts into fluid flow channels, disturb the flow, increasing turbulence and hence the heat transfer rate.
