Flexible solar cells developed for PV application

BEIJING, June 7 (Xinhua) -- Chinese researchers have provided a strategy for fabricating large-scale, foldable silicon wafers and manufacturing flexible solar cells, according to a recent research article published in the journal Nature.

A textured crystalline silicon wafer always tends to crack at the sharp channels between surface pyramids in the marginal region of the wafer. Therefore, it is necessary to impr
