Tesla and Panasonic to kill cobalt curse

Panasonic announced an aim to produce batteries for Tesla without using cobalt, much of which is sourced from the unstable and conflict-ridden Congo. June 5, 2018John WeaverOnly a few years ago, there were popular predictions that we would run out of oil, whereas today it, appears more likely that oil markets will suffer from peak demand, not supply. Similar arguments about resource scarcity have surfaced widely in anti-renewable propaganda, with concerns expressed about rare earths, lithium and other materials as easily debunked reasons why solar, wind and energy storage cannot scale.Some of these concerns could have been valid, were it…

40% of energy storage pipeline is co-located with solar PV

Since I'm at an energy storage conference in Boston today, this is a great story to lead with today - and its really telling. 40% of large scale solar in the development pipeline - that's a lot. The reason this is so fundamentally important is that we know the sun goes down - but we also really need to be able to take advantage of the cheap, clean energy from solar. And this is starting to happen today. All over the country we're seeing solar power start to get coupled with energy storage. We've seen the largest projects bid in…

GreatCell Solar gets perovskite money for a real project

Perovskite has held onto the headlines. The goal is to create a solar cell made of much cheaper materials with higher efficiencies. The material is showing greater promise - 26.4% when combined with standard silicon solar cells. Oxford PV is building a factory - and other groups suggest perovskite sales might happen in a commercial setting in 2018. Now, a great Australian group (that has also signed a research deal with a pretty large solar manufacturer) is getting money to install a system. A small one - but a real one that we can touch. Yes, the long term window…

Hanergy swings at Tesla with a thin-film solar tile

Tesla Solar Roof - RGS Energy Powerhouse - Hanergy Solar - and others. The market definitely believes that you homeowners are interested in a product different than standard rectangle solar panels. In my history of residential solar construction, I met plenty of homeowners who were focused on aesthetics. The Harergy play is interesting for two reasons 1. Hanergy is a big company and can make something happen. 2. Hanergy is using a thin film solar cell, and they are one of the world's leaders at making a high efficiency thin film product. (more…)

Tiny little beads bend light, increase solar cell absorption up to 20%

Even after reading the actual research paper, I still had a hard time understand exactly what is leading toward this increase in efficiency...a lot of big optics related words in here. The main reason I wanted to understand exactly how the light was being manipulated is because the solar material material used - gallium arsenide - is not our standard silicon, and I wanted to understand if the technology could be directly applied to a mass market.
