Ascent Solar Technologies, Inc. announced preliminary revenue results for the second quarter and six months ended June 30, 2015. For the second quarter of 2015, the company is expected to report revenue of $2.2 million, a threefold increase from first quarter of 2015. The increase in quarterly revenue is the result of a strong shipment backlog which carried over from the first quarter of 2015.

For the first half of 2015, revenue is expected to be $2.9 million, reflecting significant growth of approximately 60% over the same period in 2014.

With shipments already lining up for the rest of the year and a stronger retail presence established, the company is comfortable to reiterate its earlier revenue guidance of $10 million to $12 million for the full year 2015, which would represent growth of approximately 100% over 2014.
