Quantum Dots PV Maker

This will be a relatively brief post.  One of the new advances in photovoltaic (PV) technology is the use of quantum dots.  The quantum dot technology was pioneered by Los Alamos National Lab (LANL), though others had been working on it as well, especially scientists in China.  Quantum dot technology was discussed in Energy Central in 

There have been recent developments in quantum dot technology in China, as in 

The problems with the standard quantum dot technology is that it uses lead - the Chinese work uses lead halide.  If the PV cell breaks, you have lead leakage into the environment.

A very general introduction to the LANL work in the area is 

and more detailed information is at 

The advantage of the LANL technology is that it does not use lead.  

UbiQD is commercializing the LANL work.  Recent details about how UbiQD is doing are at
