Selenium prices in China, meanwhile, are underpinned by demand from the glass and manganese sectors.

5N Plus and First Solar signed a cadmium-telluride deal going out until 2019. President and ceo of 5N Plus Jacques L’Ecuyer said that while it “conceded competitive pricing”, that would be “largely compensated for over the course of the next quarters by the increase of sales volume”.
