Paper Abstract

In this work, we study a high efficient four-junction solar cells using AlAsSb(1.91eV), AlInAs(1.46eV), ALGaInAs(1.0eV) and InGaAs(0.75eV) materials. The >35% efficiency is calculated under AM0, and the thickness of each layer is adjusted to equalize the short circuit current. We also experimentally fabricated a 1.0eV cell and studied its characteristics.
