Exceeding the Single-Junction Shockley-Queisser Threshold
Single p-n junction silicon cells are mathematically capped at 33.7% theoretical efficiency due to thermalization loss of high-energy blue photons; stacking bandgaps harnesses high and low energy photons separately.
Atomic Layer Deposition (ALD) for Recombination Tunnel Junctions
Connecting the top and bottom cells with ultra-thin titanium oxide and indium tin oxide transparent conducting layers minimizes series resistance and recombination losses.
Halide Segregation and Light-Induced Phase Instability
Mixed iodide-bromide perovskites suffer phase segregation under concentrated sunlight, which is mitigated through cesium and rubidium cation doping into the crystal lattice.
