      abstract     = {The performance of InAs/GaAs quantum dot solar cells was
                      investigated up to an optical concentration of 500-suns. A
                      high temperature spacer layer between successive layers of
                      quantum dots was used to reduce the degradation in the open
                      circuit voltage relative to a control device without quantum
                      dots. This improvement is explained using optical data while
                      structural imaging of quantum dot stacks confirm that the
                      devices are not limited by strain. The evolution of the open
                      circuit voltage as a function of number of suns
                      concentration was observed to be nearly ideal when compared
                      with a high performance single junction GaAs solar cell.
                      Analysis of Suns-Voc measurements reveal diode ideality
                      factors as low as 1.16 which is indicative of a low
                      concentration of defects in the devices.},
