Large area (1 x 1 cm{sup 2}) Ga{sub 0.84}In{sub 0.16}As{sub 0.68}P{sub 0.32} solar cells with a band-gap of 1.50 eV were grown by gas-source MBE on GaAs substrates. Both n-on-p and p-on-n structures were fabricated and studied. The n-on-p cells showed significantly better total area conversion efficiencies (14.3% at AM0, 1-sun, with 20% of grid obscuration) than p-on-n structures (10.5%, same conditions) due to longer minority carrier lifetimes in the p-type and heavily doped n-type emitter layers.
