Simple (YGa)2O3/F‐SnO2 Heterojunction‐Based Solar‐Blind Ultraviolet Photodetector Operable in Two Modes With Superb Performance

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Yttrium doping was proposed to expand the bandgap and inhibit the oxygen vacancies of Ga2O3 to form (YGa)2O3 alloy with reduced background carriers and trap centers. Beneficially, simple vertical‐structured (YGa)2O3/FTO heterojunction photodetectors exhibit superb performance with particularly low dark current and fast photoresponse in both self‐driven

Predicting Parameters Affecting Building Energy Consumption Using Machine Learning Models

open access: yesEnergy Science &Engineering, EarlyView.
This framework integrates long‐term weather forecasting with building energy simulation to predict energy demand. The CNN–LSTM model achieved the highest accuracy (R2 ≈ 0.95), supporting smart HVAC control with ~ 15% energy savings. ABSTRACT The rapid growth of population and the construction industry have led to an increase in energy demand and an ...

Adaptive Hybrid Energy Harvester Integrating PV, TEG, and Piezoelectric Sources With Real‐Time Power Management and Experimental Validation

open access: yesEnergy Science &Engineering, EarlyView.
An adaptive hybrid energy harvester combining photovoltaic, thermoelectric, and piezoelectric sources is experimentally demonstrated. Real‐time power management dynamically allocates and conditions multisource inputs, achieving improved robustness and efficiency under variable environmental conditions compared with single‐source harvesting.

The Question of Thermoelectric Devices Electrical Resistance—A Practical Investigation From a Peltier Effect (Thermoelectric Cooler/Thermoelectric Heater) Perspective

open access: yesHeat Transfer, EarlyView.
ABSTRACT Thermoelectric devices (TEDs) intrinsic electrical resistance is fundamental to its operation. This internal electrical resistance value negatively affects a TED's performance when it is operated as a thermoelectric cooler (TEC), and positively affects a TED when operated as a thermoelectric heater (TEH).
