The Cost of Ownership and Minimum Sustainable Price of POLO BJ Cells Produced in Germany

Advanced Energy and Sustainability Research, Volume 7, Issue 4, April 2026.
The p‐type back junction (BJ) solar cell featuring n+‐type passivating poly‐Si on oxide (POLO) emerges as a promising alternative to the established PERC concept. This study compares the cost of ownership (CoO), minimum sustainable price (MSP), and the levelized cost of electricity (LCOE) of POLO BJ and PERC solar cells, with a focus on the potential ...

Evaluation of 3D‐Printed Resin Materials for Use in Microbial Bioprocess Applications: Suitability and Autoclavability

Engineering in Life Sciences, Volume 26, Issue 4, April 2026.
ABSTRACT Three‐dimensional (3D) printing technologies are continually advancing, significantly broadening their application scope. By employing fused deposition modeling (FDM) to create iterative prototypes and stereolithography (SLA) for crafting functional components, these additive manufacturing techniques offer a highly efficient solution regarding

Development of a Two‐Stage Cold Pressing and Tempering Process of Graphite Compound Bipolar Plates

Fuel Cells, Volume 26, Issue 2, April 2026.
ABSTRACT Proton‐exchange membrane fuel cells (PEMFCs) are considered a key technology for decarbonized energy systems, particularly in combination with sustainably sourced green hydrogen. The functional performance and reliability of core components, such as bipolar plates (BPPs), depends critically on the manufacturing processes. This study explores a

Laying the Foundation for Digital Material Design of Porous Transport Electrodes for PEM Water Electrolysis With Multiscale Tomography

Small, Volume 22, Issue 22, 17 April 2026.
This paper presents the first multiscale identical location tomography of a porous transport electrode for PEM water electrolysis. Different tomography and modeling approaches determine the relevant structural properties ranging from micrometer‐thick fibers to nanometer‐thin binder films covering the catalyst particles.

Periodic and Statistically Distributed Surface Texturing of Surface‐Enhanced Raman Spectroscopy (SERS) Sensors with Spatially Selective Signal Mapping

Advanced Physics Research, Volume 5, Issue 3, March 2026.
Molecular fingerprinting for the detection of biomolecules is highly sensitive and noninvasive through the surface‐enhanced Raman scattering (SERS) effect. This is a report on the commercially competitive performance of gold‐coated periodic structures and black Si (aperiodic) nanostructures as plasmonic SERS substrates.

Green‐lighting biofuels from microalgal lipids: A review of strategies to integrate stress into continuous cultures

Biofuels, Bioproducts and Biorefining, Volume 20, Issue 2, Page 1196-1210, March/April 2026.
Abstract The vision of using microalgae to obtain organic chemicals in a carbon‐neutral manner is intriguing. It promises to produce various substances including biofuels by photosynthesis, without competing with agricultural land. Processes have been established whereby microalgae undergo a growth phase followed by a stress phase, which induces lipid ...
