Thin-film solar cells manufacturer AQT Solar has received US$18.7 million from investors to double production at its headquarters in Sunnyvale, California, US. Details of the investors have not been disclosed.
A spokesman said the funding will increase the capacity of the manufacturing site to 30MW per year.
The company’s products are made with copper, indium, gallium and selenium instead of silicon used in conventional solar cells. AQT claims its manufacturing is more efficient than competitors because it uses equipment used in the computer hard disk drive industry.
