3D printing goes solar

3D printing guru Joshua Pearce wants nothing more than to provide the means of production to everyone, especially people in developing regions who must get by on very little. But there has been a drawback.

A better way to connect solar, wind to the grid

The sun makes sidewalks hot enough to fry eggs, the wind blows hard enough to tear fences, but if solar and wind energy can't be converted to the 60-hertz alternating current (AC) standard in the United States, it can't be ...

INL, ISU team on nanoparticle production breakthrough

Every hour, the sun floods Earth with more energy than the entire world consumes in a year. Yet solar power accounts for less than 0.002 percent of all electricity generated in the United States, primarily because photovoltaic ...

Silicon carbide solutions to solar challenges revealed

STMicroelectronics is revealing innovations in silicon carbide devices at Solar Power International (SPI) 2012 that enable systems producers to build ultra-efficient electronics for converting raw solar energy into grid-quality ...

Renewable energy use gaining worldwide: IEA

Renewables like solar and wind represent the fastest-growing source of energy power generation and will make up a quarter of the global power mix by 2018, the International Energy Agency said in a report Wednesday.

Solar concentrator increases collection with less loss

(PhysOrg.com) -- Converting sunlight into electricity is not economically attractive because of the high cost of solar cells, but a recent, purely optical approach to improving luminescent solar concentrators (LSCs) may ease ...

Preparation of F-passivated ZnO for quantum dot photovoltaics

For photovoltaic power generation, pn junction is the core unit. The electric field in the junction can separate and transport the electron and the hole to negative and positive electrodes, respectively. Once the pn junction ...
