The Utilization of Electrochromic Materials for Smart Window Applications in Energy-Efficient Buildings

Jelle B.P., Gao T., SINTEF Building and Infrastructure / Norwegian University of Science and Technology (NTNU), NO

The utilization of electrochromic materials (ECM) and windows (ECW) for smart window applications in energy-efficient buildings has a large potential. The ECWs are able to regulate the solar radiation throughput by application of an external [...]

Intelligent Energy Management and Power Distribution Panel

Chen H., Duli Technology LLC, US

Current solar photovoltaic (PV) systems for residential homes have several drawbacks. Grid tied PV systems with energy storage are very expensive, whereas grid tied PV systems without energy storage may cause unstable and unpredictable power [...]

A Self-Sufficient Weather Sensor Network for Microgrid Stabilization

Luong K., Chong C., Dorman Z., Hara S., Luong K., Obatake C., Pham A., Walser R., Kuh A., Renewable Island Energy Sustainability, US

To get environmental data we have created a self-sufficient environmental weather sensor network consisting of sensor network nodes that each get environmental data.. Powered by a 15,600 mAh lithium ion battery pack, a 3.7W solar [...]

Potential of Water‐Responsive Materials to Harvest Energy from Evaporation

Cavusoglu A.‐H., Chen X., Sahin O., Columbia University, US

Water-responsive materials swell and shrink in response to changes in relative humidity (RH) and can be potentially used to harvest energy from evaporating water. Here, we investigated the potential of harvesting energy from naturally evaporating [...]

Light Trapping in Solar Cells Using Nanostructured Reflectors: A Responsivity-Based Model Applied to Waveguide Mode Matching

Shahriad T., Shepard S.R., Louisiana Tech University, US

Although theoretically predicted that periodic photonic nanostructures can outperform the pseudo random structures in light trapping in solar cells, still the disputation regarding this topic is at the top. To enlighten the world about the [...]
