Could ‘hot carrier’ solar cells break the theoretical efficiency limit?
Up to 50% of the energy absorbed by a solar cell is lost as heat. Scientists are now developing a third generation of “hot carrier” solar cells that take advantage of this heat, potentially breaking the Shockley-Queisser limit of silicon-based PV.
Semi-transparent organic photovoltaic filters for agrivoltaic greenhouses
Researchers in the United States have tested organic photovoltaic filters in a greenhouse hosting lettuce growth and have found the devices’ transmission spectra may help fine-tune the characteristics of the plant. They used transcriptomic analysis to assess the key modifications of the plants grown under the solar filters.
Solar-powered data server network developed to frame the internet as a natural resource
The Solar Protocol website maps solar exposure across the globe, activating data cloud centers when the sun shines. Developed by the NYU Tandon School of Engineering, the project intends to draw attention to the energy intensity of data processing, and to offer a more climate-friendly solution.
Sunrise brief: Industry efforts prevented Florida rooftop solar bill from being potentially disastrous
Also on the rise: Solar advocates oppose Duke’s proposed NEM 2.0 in North Carolina. Indiana enables renewable-ready communities. In Virginia shared solar customers could see fixed charge. Solar+food in ethanol fields could fully power the United States. Federal support needed for US to reach 39% of carbon-free energy sector by 2035. RMI Study suggests charging EVs at work not home, to put daytime solar power to work.
Solar+food in ethanol fields could fully power the United States
Converting the nation’s 40 million acres of ethanol corn farms into solar-plus-food facilities would generate 1.5 times our nation’s electricity needs, while also powering a 100% electrified passenger vehicle fleet.
Lawrence Berkeley report outlines shifts in demographics of US residential solar adopters
Less affluent households are adopting residential solar but higher incomes found among solar-plus-storage users.
Lithium beneath the Salton Sea
The geothermal field beneath California’s Salton Sea contains brine that may hold from one to six million metric tons of lithium, an essential element for producing batteries. A Berkeley Lab study aims to evaluate the resource.
NREL launches 100% renewables study for Puerto Rico
Puerto Rico has 40GW of solar potential, said national lab staff in a webinar. The 100% study will begin by modeling the renewables milestones set by Puerto Rico law.
Solar cells used for high-speed underwater wireless data transmission
Breaking research reveals solar cells can be used as lens-free, high-speed optical detectors in underwater environments. The research team said the devices may offer a lower-cost alternative to lensed devices.
NREL continues to explore marine wave energy
While there are mechanical and cost issues that currently block widespread adoption of wave energy, the National Renewable Energy Laboratory is exploring new ways to harness the power of the ocean’s waves.
