Research Challenge 0: Overarching and spillover research

The “zeroth” scientific research challenge is what we call overarching and spillover research. “Overarching” research is what connects the six main scientific research challenges to SSL technology. SSL technology is itself evolving rapidly, and we devote some effort to understanding this evolution so as to provide guidance for the directions of our inquiry to surmount [...]

Brief History of Solid-State Lighting Technology

Semiconductor electroluminescence was first reported by H.J. Round in 1907, and the first light-emitting diode (LED) was reported by O.V. Losev in 1927. Not until the birth of semiconductor physics in the 1940s and 1950s, however, was scientific development of technologies for light emission possible. For solid-state lighting (SSL), using semiconductor electroluminescence to produce visible [...]

Power Towers for Utilities

Desirable Features of Power Towers for Utilities Because of their practical energy storage, solar power towers have two features that are particularly desirable for utilities: flexible capacity factors and a high degree of dispatchability. Power towers can be designed with annual capacity factors up to 60 percent, and as high as 80 percent in summer [...]
