    Electrek green energy brief: 1.5GW RFP in AZ, Perovskite at 30% in two years (!?), Apple backing energy storage, more


    Arizona County put out Request for Proposal (RFP) for 1.5GW of solar power – Personally, this is the largest RFP I’ve seen in the US. There are headlines for projects in the Middle East at 5GW, one in India at 7.5GW and China sorta has an RFP of 20GW a year – but these nation-state led bids feel different than a county in the state of Arizona. 8,800 acres of desert (less than .005% of the more than 1.8 million acres of federal lands controlled by the Bureau of Land Management (BLM) in La Paz County). This project will cost $1/W’ish – $1.5B in cost. And there is already a transmission line project in development to move the power. I’d love to get a commission on $1.5B…

    23.6% achieved with perovskite – plus stability increases: The real reason I grabbed this article, other than a fascination with base level research, was this quote – ‘“The best silicon solar cell alone has achieved 26.3% efficiency,” says Zachary Holman, an assistant professor of electrical engineering at ASU’s Ira A. Fulton Schools of Engineering. “Now we’re gunning for 30% with these tandem cells, and I think we could be there within two years.”’ I’ve never heard of someone seriously considering hitting 30% solar cell efficiency. Yesterday, we saw SunPower at 25% on a production line and how that was 50% greater than average panels – imagine the labs being at double average panels in two years…wow.
