"resilience of novel solar cell... hot carrier multijunction solar cell (HCMJSC), to nonideal design with nonoptimal materials... consisted of thin hot carrier top junction series connected to thick cold bottom junction... HCSC demonstrated highest PCE, followed by HCMJSC and MJSC... HCMJSC more relaxed requirements on hot carrier thermalization compared to HCSC... all three designs showed lower efficiency... low-bandgap HCMJSCs were slightly more sensitive to illumination effects"
