Agrivoltaics for radicchio
An Italian research team has found that radicchio seedlings grown in a lab-scale greenhouse with a perovskite solar PV roof exhibited faster growth and larger leaves than the bare glass reference. In addition, simulations of such a PV roof revealed a positive energy balance, satisfying the energy demands of a typical greenhouse located in Italy.
