Once seen as fleeting, a new solar tech proves its lasting power

Princeton Engineering researchers have developed the first perovskite solar cell with a commercially viable lifetime, marking a major milestone for an emerging class of renewable energy technology. The team projects their device can perform above industry standards for around 30 years, far more than the 20 years used as a threshold for viability for solar cells. The device is not

Solar-biomass hybrid system satisfies home heating requirements in winter

Adding an organic matter power source to a solar energy unit could provide 100% heating for a single-story home during the coldest months of the year and help the environment. In the warmer months, the system could generate electricity surpluses that can be sold back to the grid. In Journal of Renewable and Sustainable Energy, published by AIP Publishing, researchers in

Engineers enlist AI to help scale up advanced solar cell manufacturing

Perovskites are a family of materials that are currently the leading contender to potentially replace today’s silicon-based solar photovoltaics. They hold the promise of panels that are far thinner and lighter, that could be made with ultra-high throughput at room temperature instead of at hundreds of degrees, and that are cheaper and easier to transport and install. But bringing these

Solar cell keeps working long after sun sets

About 750 million people in the world do not have access to electricity at night. Solar cells provide power during the day, but saving energy for later use requires substantial battery storage. The device generates electricity at night from the temperature difference between the solar cell and its surroundings.

Materials scientists finding solutions to biggest hurdle for solar cell technology

Materials scientists at the UCLA Samueli School of Engineering and colleagues from five other universities around the world have discovered the major reason why perovskite solar cells — which show great promise for improved energy-conversion efficiency — degrade in sunlight, causing their performance to suffer over time. The team successfully demonstrated a simple manufacturing adjustment to fix the cause of
