Technology and R&D

A breakthrough for p-type heterojunction cell performance?

Researchers developed a silicon heterojunction solar cell based on p-type gallium-doped wafers that they said has an efficiency of 22.6% and improved stability.

New battery chemistry tweak could double electric vehicle range

Researchers at the Pacific Northwest National Laboratory have developed a revolutionary lithium-metal battery chemistry that they believe will allow EV batteries to almost double capacity, while also overcoming historic setbacks.

Sunrise brief: New York power plant will swap renewable hydrogen for natural gas

Also on the rise: SoCalEdison launches a $436 million EV charge program; Ohio adds a hurdle for renewable project developers; and Cummins begins testing a hydrogen-fueled ICE.

By addressing heat, this serial inventor just may change the entire solar value chain

Kent Kernahan set out to take the heat out of solar cells. He and his partners may end up bringing solar manufacturing jobs to disadvantaged communities and making low-cost rooftop solar widely available.


Improving solar cells by tackling noise

Researchers used noise measuring devices to identify physical processes within solar cells that cause energy loss and lower efficiency.

Solar beach umbrella design cools you… and your gelato

An origami-inspired umbrella that can power a refrigerator was designed by an MIT-spawned innovation firm along with architects and an Italian frozen-desserts brand.

Do engineers dream of solar panel efficiency?

A true next generation of solar cell technology is upon us. It is time to contemplate the benefits.


Urban Electric Power’s long-term storage solution takes battery storage back to the basics

Using a modified version of the same technology used in AA batteries, Urban Electric Power was accepted into EPRI’s Incubatenergy Labs program to prove their technology’s worth in front of some of the nation’s top utilities.


Renewables up to 90% by 2050 would cost less than current generation mix: NREL study

Even 100% renewables could be reached with existing technology, the study said. Stanford University’s Mark Jacobson commented that system costs would be even lower with additional measures.

More than a view: Here are 3 solar energy-producing windows

These companies are producing solar energy generating windows, flexible surfaces, and blinds as a creative, distributed way to meet the energy demand of buildings.
