  The possibility to exploit quantum coherence to strongly enhance the
efficiency of charge transport in solid state devices working at ambient
conditions would pave the way to disruptive technological applications. In this
work, we tackle the problem of the quantum transport of photogenerated
electronic excitations subject to dephasing and on-site Coulomb interactions.
We show that the transport to a continuum of states representing metallic
collectors can be optimized by exploiting the "superradiance" phenomena. We
demonstrate that this is a coherent effect which is robust against dephasing
and electron-electron interactions in a parameters range that is compatible
with actual implementation in few monolayers transition-metal-oxide (TMO)
heterostructures.
