“…21 Green-light wavelength-selective OSCs can generate electricity by using the energy in the green-light region, while the transmitted blue and red light can be utilized to grow crops. To realize this concept, we selected practical and cost-effective poly-3-hexylthiophene (P3HT) as the donor, [22][23][24][25][26][27][28][29][30] because P3HT has a selective absorption in the green wavelength region (Fig. 1c).…”

“…We have developed substituted naphtho[1,2- c :5,6- c ’]bis[1,2,5]thiadiazole ( NTz ) compounds, namely, fluorinated NTz ( FNTz ) − and cyano-substituted NTz ( CNNTz ), , as new electron-accepting units, and subsequently, these compounds are applied to develop π-conjugated systems for use as NFAs in OSCs (Figure ). , The NFA CNNTz-RD , which is based on CNNTz and 3-ethylrhodanine ( RD ), is synthesized, and its solar cell characteristics are evaluated in combination with the typical PBDB-T donor . However, due to the strong electron-accepting nature of CNNTz , the prepared CNNTz-RD is not suitable for P3HT-based OSCs.…”

The complemental absorption behavior of donors and acceptors in organic solar cells (OSCs) results in the broad absorption of solar light, contributing to the realization of high-performance OSCs. However, the development of OSCs with narrow absorption ranges, i.e., wavelength-selective OSCs, has made slow progress owing to their limited applications. Here, green-light wavelength-selective OSCs, whose transmitted blue and red light can be effectively used to promote plant growth, are proposed. For the preparation of green-light wavelength-selective OSCs, a practical polymer of poly(3-hexylthiophene) (P3HT) is employed as the donor and naphthobisthiadiazole-based compounds (SNTz-RD and ONTz-RD) are newly designed as the acceptors. The electronic absorption measurements of SNTz-RD and ONTz-RD show strong absorption bands in the green-light region. In addition, SNTz-RD and ONTz-RD possess appropriate frontier orbital energy levels as acceptors. OSCs based on P3HT and these acceptors show typical photovoltaic responses with good green-light wavelength-selective factors and good power conversion efficiencies in the green-light region. Furthermore, the P3HT:SNTz-RD blend films exhibit an improved photosynthetic rate in the strawberry leaves compared to the conventional P3HT:[6,6]-phenyl-C61-butyric acid methyl ester (PC61BM) film. These results demonstrate that the combination of P3HT and green-light wavelength-selective acceptors can produce green-light wavelength-selective OSCs for application in new greenhouse agrivoltaics.
