Basic Research of Self-Organized Quantum Dots and their Potential In Solar Cells and Novel Device Applications (Phase 3)

Abstract

Aim to achieve a minimum of 30 % conversion efficiency solar cells using Quantum Dot Molecule (QDM) structure QDM. Solar Cells are simpler to fabricate than tandem (Multijunction) solar cells. The QDM solar cells have very high efficiency (60 % in theoretical calculation) solar energy conversion. Achieve QDMs with high dot density (~1012 cm-2), good dot uniformity and dot ordering are needed in this solar cell structure. Achieved 25.9 % non-optimized conversion efficiency QDM solar cell which was reported at WCPEC-4 in Hawaii. Further experiments are needed in order to optimize the number of stacked QDMs, depth of stacking QDM layers, capping materials, anti-refection coating, fine structure of grid contacts and other parameters which can make us achieve the 30% plus efficiency.
