(Cross-section view of 3J ELO solar cell containing ~1.9eV GaInP, 1.4 eV GaAs, and 1.0 eV GaInAs subcells)

Our group alumni Dr. Alex Kirk, currently the principle scientist at Microlinks Device, has been working on thin ELO multi-junction solar cells. One of the 3J cells he designed has been included as a world record ELO device in the solar cell efficiency table as shown in the LINK (bottom of Table 3 on p. 6 with EQE & I-V shown in Fig. 3 on p. 10). More details about the cell are outlined can be found in the 2018 conference paper. These 3J ELO cells allowed Airbus to recently set a new world aviation endurance record as profiled in the LINK. The flight occurred in Arizona on the 11th of July, 2018.
