Throughout its brief history, California has established itself as a national or international leader in key industries—such as aerospace, computing and entertainment—through early mover pre-emption and strong clustering effects. California firms were the initial world leaders in producing...

I have stated in my recent review article that no direct observation of multiple exciton generation (MEG) in the shape of photocurrent extracted from a semiconductor had been made yet. [...]

Record volumes of solar PV power plant installations have been achieved on the back of feed-in-tariffs and fiscal incentives. On the supply side, however, equipment manufacturers have been filing for bankruptcy protection in quick succession. This paper is an attempt to unravel the mystery...

It is commonly assumed that because of its relatively high solar energy incidence Australia will be able to meet its energy demand from solar sources. However, an examination of evidence on existing and probable future efficiencies and costs indicates that it will not be possible to derive...

Solar cells are a promising renewable, carbon-free electric energy resource to address the fossil fuel shortage and global warming. Energy conversion efficiencies around 40% have been recently achieved in laboratories using III-V semiconductor compounds as photovoltaic materials. This article...

An effective energy technology strategy has to balance between setting a stable long term framework for innovation, while also responding to more immediate changes in technology cost and performance. Over the last decade, rather than a steady progression along an established learning curve, PV...
