By covering greenhouses with semi-transparent solar panels, sunlight can be exploited to generate electricity, allowing at the same time the healthy growth of plants. Perovskite-based halide solar cells appear to be the ideal candidate to achieve this goal, being also an environmentally friendly solution. Here, we report preliminary data concerning the influence of the lead-free Cs2AgBiBr6 perovskite, used as active layer for solar cells panels, covering the in-door green-house, on plant growth and metabolite contents of Artemisia annua L. The experiments were carried out "in-door" in a growth chamber with controlled conditions of light and temperature, using mini green-houses covered by transparent glass panels placed on the control green-houses (P-), and semi-transparent panels, constituted by glass covered by indium tin oxide (substrate) and Cs2AgBiBr6 perovskite layers (P+). A. annua plants were grown in pots placed inside P- and P+ mini green-houses. From well grown plants (about 90 days), the first leaves were picked up for chlorophyll analysis, while the remaining leaves and stems used for evaluating artemisinin contents. The average of total chlorophylls (a+b) in (P+) plants was more than 2-fold higher than control (P-) plants (1.68 vs 0.73 mg/g FW). Differently, preliminary results of artemisinin contents indicate that the Perovskite "screen" negatively affected metabolite accumulation.

Abstract
By covering greenhouses with semi-transparent solar panels, sunlight can be exploited to generate electricity, allowing at the same time the healthy growth of plants. Perovskite-based halide solar cells appear to be the ideal candidate to achieve this goal, being also an environmentally friendly solution. Here, we report preliminary data concerning the influence of the lead-free Cs2AgBiBr6 perovskite, used as active layer for solar cells panels, covering the in-door green-house, on plant growth and metabolite contents of Artemisia annua L. The experiments were carried out "in-door" in a growth chamber with controlled conditions of light and temperature, using mini green-houses covered by transparent glass panels placed on the control green-houses (P-), and semi-transparent panels, constituted by glass covered by indium tin oxide (substrate) and Cs2AgBiBr6 perovskite layers (P+). A. annua plants were grown in pots placed inside P- and P+ mini green-houses. From well grown plants (about 90 days), the first leaves were picked up for chlorophyll analysis, while the remaining leaves and stems used for evaluating artemisinin contents. The average of total chlorophylls (a+b) in (P+) plants was more than 2-fold higher than control (P-) plants (1.68 vs 0.73 mg/g FW). Differently, preliminary results of artemisinin contents indicate that the Perovskite "screen" negatively affected metabolite accumulation.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
