Enhanced Bandgap Flexibility in Perovskite‐Silicon Tandem Solar Cells via Three‐Terminal Architecture

open access: yesAdvanced Science, EarlyView.
Three‐terminal (3T) perovskite/silicon tandem solar cells overcome the current‐matching constraints of 2T designs. Using an IBC POLO silicon bottom cell, we demonstrate a 30.1% PCE, with performance largely decoupled from perovskite bandgap and enhanced resilience under realistic, time‐dependent solar spectra.

Toward a Cognitive Experimental Economics [PDF]

open access: yes
This paper aims to analyze and exemplify some methodological implications on the way to conduct experiments related to the adoption of a cognitive approach in Economics. Many differences arise in relation to a more traditional way.

Electrochemical Nitrate Reduction Reaction to Ammonia at Industrial‐Level Current Densities

open access: yesAdvanced Science, EarlyView.
This review starts from the mechanism and theoretical basis of electrochemical nitrate reduction reaction (NO3−RR), and systematically summarizes and discusses the design strategies of industrial‐level current density catalysts. In addition, the progress of industrial‐level NO3−RR‐based electrolyzers, including flow reactor and membrane electrode ...

Neural Information Processing and Time‐Series Prediction with Only Two Dynamical Memristors

open access: yesAdvanced Electronic Materials, EarlyView.
The present study demonstrates how simple circuits with only two memristive devices are utilized to perform high complexity temporal information processing tasks, like neural spike detection in noisy environment, or time‐series prediction. This circuit simplicity is enabled by the dynamical complexity of the memristive devices, i.e.

Bio‐Inspired Cascade Photocatalysis on Fe Single‐Atom Carbon Nitride Upcycles Plastic Wastes for Effective Acetic Acid Production

open access: yesAdvanced Energy Materials, EarlyView.
This work demonstrates a novel cascade photocatalysis concept using Fe single‐atom catalysts (Fe@C3N4 SAC) to directly upcycle plastics (PET, PP, PE, PVC) into valuable acetic acid at ambient conditions. Inspired by microbial degradation, the bifunctional cascade photocatalyst combines Fenton‐like oxidation and CO2 photoreduction, as validated by ...

Endogenous Choice of Institution under Supply and Demand Risks in Laboratory Forward and Spot Markets

open access: yesJournal of Agricultural and Resource Economics, 1999
Laboratory methods are used to investigate the impacts of supply and demand risks in a forward market on prices, quantities traded, and earnings when the choice of transacting in a forward or spot market is endogenous.

Foundations of Behavioral and Experimental Economics: Daniel Kahneman and Vernon Smith [PDF]

open access: yes
Advanced information on the Prize in Economic Sciences 2002. Until recently, economics was widely regarded as a non-experimental science that had to rely on observation of real-world economies rather than controlled laboratory experiments.
