Global revenue for PV cells is projected to increase to as much as $22.1 billion in 2012, up from $9.6 billion in 2007, according to a preliminary forecast from iSuppli Corp.
By 2020, about 50,000 Megawatts worth of PV systems (MWp) will be installed annually, up by a factor of nearly 20 times from 2,538MWp in 2007. MWp is a metric that measures the power output of solar cells...
