Boosting Bifacial Output Power of Ag‐CIGS Solar Cells by Optimizing ITO Back‐Contact Thickness for Tandem Applications

open access: yesCarbon Energy, EarlyView.
Optimized ITO back contact with pre‐Ga supply growth and Ag incorporation suppresses GaOx formation and interface recombination in bifacial CIGS solar cells. The devices achieve 17.25% front and 5.77% rear efficiency, delivering record bifacial power density up to 32.26 mW cm−2 in 4T perovskite/CIGS tandem architectures under enhanced albedo ...

Development of a Mechanically Regenerating Desublimator for Freeze‐Drying Systems in the Food Industry

open access: yesChemie Ingenieur Technik, EarlyView.
Thermal defrosting limits desublimator efficiency in freeze‐drying. This review and case study compares thermal versus mechanical regeneration, links frost properties and external heat transfer to energy demand, and summarizes pilot‐scale scraping results enabling single‐unit, continuous lyophilization.

Reliability Analysis of a Steel Frame

open access: yesActa Polytechnica, 2002
A steel frame with haunches is designed according to Eurocodes. The frame is exposed to self-weight, snow, and wind actions. Lateral-torsional buckling appears to represent the most critical criterion, which is considered as a basis for the limit state ...

Experimental methods in chemical engineering: The scientific method versus engineering design methodology

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Abstract Engineering graduate students confuse the scientific method and problem solving when presenting their pre‐doctoral exams and theses: Science discourse adopts question and hypotheses to assert and establish a study's rationale, while it is problem and objectives in engineering design.

Assessment of Automated Snow Cover Detection at High Solar Zenith Angles with PROBA-V

open access: yesRemote Sensing, 2016
Changes in the snow cover extent are both a cause and a consequence of climate change. Optical remote sensing with heliosynchronous satellites currently provides snow cover data at high spatial resolution with daily revisiting time.

Cloud-Gap Filtering for Reliable MSG-SEVIRI-Based Snow Cover Records

open access: yesThe International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences
Abstract. Snow cover is a key variable for climate monitoring and hydrological applications, yet optical satellite observations are strongly limited by cloud contamination, particularly during winter. The EUMETSAT H SAF H34 snow product derived from MSG-SEVIRI uses the unique 15-minute temporal resolution over the full SEVIRI disc to clear the clouds ...
