Manufacturing Bits: June 20


Solar cell metrology Using atomic force microscopy (AFM), the National Institute of Standards and Technology (NIST) has developed a pair of novel techniques to measure the chemical compositions and defects in solar cells. The new techniques will give researchers insights into a thin-film solar cell material called cadmium telluride. The technology will also suggest ways to boost the efficie... » read more

Power/Performance Bits: May 10


Non-toxic thin-films A team at Australia's University of New South Wales achieved the world's highest efficiency using flexible solar cells that are non-toxic and cheap to make, with a record 7.6% efficiency in a 1cm2 area thin-film CZTS cell. Unlike its thin-film competitors, CZTS cells are made from abundant materials: copper, zinc, tin and sulphur, and has none of the toxicity problems... » read more
