Green light wavelength-selective organic solar tech for greenhouses

https://www.pv-magazine.com/2024/09/05/green-light-wavelength-selective-organic-solar-tech-for-greenhouses/

Japanese scientists have built organic solar cells and modules by utilizing donors and acceptors that are green light selective. They used a blend of poly(3-hexylthiophene) and fluorinated-naphthobisthiadiazole.

A research team at Osaka University in Japan has developed green light wavelength-selective organic solar cells (OSCs) that transmit blue and red light necessary for crop growth and use green light, which contributes only a little to photosynthesis, for power generation.

If this was efficient enough you could use them to shade plants to keep the summer heat down while also giving them full light. Hopefully it's feasible.

Similar, non-wavelength specific translucent panels were for sale a month ago when I bought my 400W traditional panels. It's not just feasible. It's already for sale.

If this works, could you theoretically cover crop fields in solar panels as well? That's a ton of usable space

Transmits, as in let's it pass through, right? Like window tint being rated as xx% visible light transmission (VLT)?

As written in the article, letting through wavelengths other than green. So, yes.

I did read it, but I realize I was stuck with a more radio-like definition of "transmit". Thanks

I swear, auto-correct intentionally picks the wrong one every time. I know because my error is not using enough apostrophes

Incredible!
