Research abstract
In the proposed Phase II project, MicroLink and its collaborator, Rochester Institute of Technology (RIT), will incorporate quantum dots (QDs) in the GaAs and InGaAs subcells of an InGaP/GaAs/InGaAs triple-junction solar cell to increase the radiation tolerance and thereby improve the end-of-life performance of the solar cell by >5%. The quantum dot solar cell will be grown in an inverted metamorphic (IMM) format on GaAs and will be compatible with MicroLink's epitaxial lift-off (ELO) process. The resulting solar cells will be lightweight, flexible, and radiation tolerant. Mechanically, they will resemble a sheet of thin metal foil. Innovative light management techniques such as reflective metal back contact and silver nanoparticle-enhanced reflectivity will be employed to increase absorption in the solar cell
