Technology could bring high-end solar to the masses
Jul 25, 2013 by Sarah Yang
Engineers at the University of California, Berkeley, have developed an
inexpensive new way to grow thin films of a material prized in the
semiconductor and photovoltaic industries, an achievement that could bring
high-end solar cells within reach of consumer pocketbooks

Researchers discover universal law for light absorption in 2D semiconductors
>From solar cells to optoelectronic sensors to lasers and imaging devices,
many of today's semiconductor technologies hinge upon the absorption of
light. Absorption is especially critical for nano-sized structures at the
interface between two energy barriers called quantum wells, in which the
movement of charge carriers is confined to two-dimensions. Now, for the
first time, a simple law of light absorption for 2D semiconductors has been
demonstrated.
