Researchers Advance Printable Solar Cell Possibilities

By finding a new way to manufacture low-cost perovskite solar cells, a team at the University of Toronto believes that making solar cells could someday be as easy and inexpensive as printing a newspaper. The researchers' alternative solar technology supports the development of low-cost, printable solar panels capable of turning nearly any surface into a power generator.

Long-Lasting Flow Battery Advances Renewable Energy Efforts

A new flow battery from the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) stores energy in organic molecules dissolved in neutral pH water. Losing only one percent of its capacity per 1000 cycles, the non-toxic, non-corrosive device offers the potential to significantly decrease the costs of production.

Electricity Generator Mimics Trees

The biomimetic tree's leaves, modeled after cottonwood leaves, rely on piezoelectrical processes to produce electricity. (Photo by Christopher Gannon) Iowa State University scientists have built a device that mimics the branches and leaves of a cottonwood tree and generates electricity when its artificial leaves sway in the wind. The device is derived from biomimetics, or the use of artificial means to mimic natural processes. Such biomimetic technology could become a market for those who want to generate limited amounts of wind energy without the need for tall and obstructive towers or turbines.

Energy Management System Cuts Hybrid Fuel Consumption by One-Third

Xuewei Qi and a team of UCR researchers are using vehicle connectivity and evolutionary algorithms to improve the efficiency of plug-in hybrid electric vehicles. Engineers at the University of California, Riverside have taken inspiration from biological evolution and the energy savings garnered by birds flying in formation to improve the efficiency of plug-in hybrid electric vehicles (PHEVs) by more than 30 percent.

System Harvests Energy from Automotive Shock Absorbers

The energy harvesting device focuses on the car’s suspension – specifically, the shock absorbers. Boosting the fuel efficiency of motor vehicles by “harvesting” the energy generated by their shock absorbers and feeding it back into batteries or electrical systems such as air conditioning has become a major goal in automotive engineering. A University of Huddersfield (UK) researcher has designed a new system and built a prototype that is ready for real-world testing.

Thermal Metamaterial for Waste-Heat Harvesting in Power Plants and Factories

The thermal metamaterial was developed in research aimed at efficiently harvesting waste heat from power plants and factories. (Purdue University/Sean Molesky) An international research team has used a thermal metamaterial to control the emission of radiation at high temperatures, an advance that could bring devices able to efficiently harvest waste heat from power plants and factories. Thermophotovoltaic devices that generate electricity from thermal radiation might be adapted to industrial pipes in factories and power plants, as well as on car engines and automotive exhaust systems, to recapture much of the wasted energy.
