Tailoring the optical properties of broad-band molecular solar absorbers embedded into a Fabry-Pérot cavity

The latest progresses in polaritonic solar devices, in which molecular absorbers and photon modes of a resonator are hybridized as a result of strong coupling regime, have revealed that light-matter interaction can be an interesting tool to control and enhance devices performances. In this talk, light harvesting properties of broadband absorbers operating under weak, strong and ultra-strong coupling regimes are discussed. The spectral and directional response, together with the effect of polaritons on unproductive absorption due to the presence of metallic films in the structure are discussed in detail. These results allow to establish the optimum configuration to exploit the potential of solar cells devised as optical resonators.
