MiaSolé, a US-based solar film company previously backed by Japan-based electricity company Nippon Kouatsu, has raised $55m.
News provider Dow Jones said existing MiaSolé investors VantagePoint Capital Partners, Kleiner Perkins Caufield & Byers, Bessemer Venture Partners, Firelake Capital Management and Passport Capital participated. A spokesman added the latest round was "primarily contributed by existing investors".
The investment follows MiaSolé raising most of a planned $125m round in February 2011, according to a previous Dow Jones report. Dow Jones said this round was at less than half the valuation of its $200m to $220m round raised in 2008, at $550m, down from a $1.2bn valuation.
It is unclear what the valuation for the latest round is.
Japan-based electricity company Nippon Kouatsu Electric Company and financial investor Venture Banking Group also backed the company in a $5.4m round in 2004.
