Abstract

Green-light wavelength-selective organic solar cells (GLWS-OSCs) pioneer novel agrivoltaics in greenhouses via transforming solar energy in the green-light region to electricity while simultaneously growing crops by utilizing the transmitted blue and red lights. However, the development of GLWS-OSCs has been stymied due to the limited availability of donors and acceptors. Herein, we investigate the combination of a cost-effective poly(3-hexylthiophene) (P3HT) donor with a fluorinated-naphthobisthiadiazole-based non-fullerene acceptor (FNTz-FA) for GLWS-OSC application. FNTz-FA shows an intense absorption band between 500 and 600 nm and a high level of chemical stability. OSCs based on P3HT and FNTz-FA with an inverted configuration are optimized to show high green-light wavelength-selective absorption and power conversion efficiency in the green-light region. Furthermore, large-scale device fabrication has been considered, leading to the development of 100 and 400 cm scale OSC modules. These modules showed sustained solar cell performance after 180 days. Photosynthetic rate measurements indicate that transmissions by the P3HT:FNTz-FA film show a non-obstructing nature and the advantage of green-light wavelength-selectivity in crop growth. Preliminary investigations on the growth of tomatoes have shown the potential of P3HT:FNTz-FA-based OSCs for agrivoltaics. These results demonstrate that GLWS-OSCs are a valid candidate to realize agrivoltaics in greenhouses for an effective utilization of solar energy.
绿光波长选择性有机太阳能电池:面向农业光伏的模块制造和作物评估
绿光波长选择性有机太阳能电池(GLWS-OSCs)通过将绿光区域的太阳能转化为电能,同时利用透射的蓝光和红光种植作物,开创了温室中新型农业光伏技术。然而,由于供体和受体的有限性,GLWS-OSC 的发展一直受阻。在本文中,我们研究了如何将具有成本效益的聚(3-己基噻吩)(P3HT)供体与基于氟化萘二噻二唑的非富勒烯受体(FNTz-FA)结合起来,用于 GLWS-OSC 应用。FNTz-FA 在 500 和 600 纳米之间显示出强烈的吸收带,并具有很高的化学稳定性。经过优化的基于 P3HT 和 FNTz-FA 的反向配置 OSCs 在绿光区域具有较高的绿光波长选择性吸收和功率转换效率。此外,还考虑了大规模器件制造,从而开发出 100 厘米和 400 厘米级的 OSC 模块。这些模块在 180 天后显示出持续的太阳能电池性能。光合速率测量结果表明,P3HT:FNTz-FA 薄膜的透射率显示出无阻碍性以及绿光波长选择性在作物生长中的优势。对西红柿生长的初步研究表明,基于 P3HT:FNTz-FA 的 OSCs 具有应用于农业光伏的潜力。这些结果表明,GLWS-OSCs 是在温室中实现农业光伏以有效利用太阳能的有效候选材料。
