cell designed for concentrated photovoltaics applications. Here we compare the
performances of two structures that could replace standard monolithic InGaAs homojuntion.
The first one is a stand-alone solar cell realized via epitaxial lift-off (ELO) process on a
flexible substrate. The second one is a heterojunction solar cell, Nept on its parent InP
substrate, composed of an InP emitter and an InGaAs absorber. A third structure made of an …
