Funding Roundup: Mega Solar Deals, Algal Biofuels and Clean Water

Investors pump $404M into two big solar deals. Meanwhile, Miox gets $19M for detoxing water and Natural Cleaners Colorado receives $1.9M for green dry cleaning.

Two mega-deals announced by Nanosolar and AVA Solar last week reflected investors' increasingly large bets on thin-film solar technologies.

Thin-film solar has conquered only a fraction of the solar market today, where most of the panels use crystalline silicon to convert sunlight into electricity. Thin films aren't as efficient at producing power, and manufacturing them in large volumes has proven challenging. But they use little or no silicon, making them an appealing option amid today's silicon shortage.

Nanosolar confirmed that it had raised $300 million in equity and closed the deal back in March. The San Jose, Calif. company plans to use the money to expand its existing factory in its hometown and to build a new one in Germany (see Nanosolar Confirms $300M Funding). It began shipping its first commercial panels, which use copper indium gallium selenide, last December.

Most of the new cash came from AES Corp, the Carlyle Group, EDF and Energy Capital Partners through Riverstone Holdings and EDF Renewables. The remainder came from Lone Pine Capital, the Skoll Foundation and the Omidyar Network, GLG Partners, Beck Energy and Grazia Equity.

AVA Solar, which is in pilot production, raised $104 million. DCM led AVA's new round of funding, which also came from Technology Partners, GLG Partners, Bohemian Companies and Invus (see AVA Solar Gets $104M).
