Abstract

Dye-sensitized solar cells (DSSCs) can be used as greenhouse-glazing materials because of their translucent properties, varied colors, and ability to produce electricity. To assess their effect on plant growth and physiological responses, Petunia ×hybrida ‘Madness Red’ was investigated under four different light treatments: transparent polycarbonate panels (T) as the control, T + 50% shade (S), red-colored DSSCs (D), and D + cool-white light-emitting diodes (LED) (D + L). Compared to T, S increased the leaf area and the number of days to flowering and decreased the number of flowers and relative chlorophyll content (SPAD). D increased the plant height, leaf area, fresh weight, and the number of days to flowering and reduced the SPAD and number of leaves and flowers due to a lower daily light integral (DLI) and blue light than T. Compared to S, D increased the plant height, leaf area, and fresh weight while reducing the number of leaves and flowers due to the lower blue light. D + L increased the number of leaves and flowers, flowering rate, dry weight, and SPAD but inhibited stem and leaf elongation compared to D, due to an increase in DLI and blue light. The deployment of red DSSCs in greenhouses could potentially induce unfavorable morphological and developmental responses in light-sensitive plants. However, these effects can be mitigated using DSSC-powered LED supplemental lighting.

通过染料敏化太阳能电池和发光二极管改良温室中的牵牛花（一种光敏植物）对光照条件的生长、开花和形态反应

摘要染料敏化太阳能电池（DSSC）因其半透明特性、不同的颜色和发电能力，可用作温室玻璃材料。为了评估其对植物生长和生理反应的影响，研究人员在四种不同的光照处理下对矮牵牛花 ×hybrida 'Madness Red'进行了研究：作为对照的透明聚碳酸酯板（T）、T + 50% 遮光（S）、红色 DSSC（D）和 D + 冷白色发光二极管（LED）（D + L）。与 T 相比，S 增加了叶面积和开花天数，减少了花朵数量和相对叶绿素含量（SPAD）。与 S 相比，D 增加了植株高度、叶面积、鲜重和开花天数，但由于日光照积分（DLI）和蓝光比 T 低，SPAD 以及叶片和花的数量有所减少。与 D 相比，D + L 增加了叶片和花朵的数量、开花率、干重和 SPAD，但由于 DLI 和蓝光的增加，抑制了茎和叶的伸长。在温室中部署红色 DSSC 可能会诱导光敏感植物产生不利的形态和发育反应。不过，使用 DSSC 供电的 LED 补充照明可以减轻这些影响。

期刊介绍： Horticulture, Environment, and Biotechnology (HEB) is the official journal of the Korean Society for Horticultural Science, was launched in 1965 as the "Journal of Korean Society for Horticultural Science". HEB is an international journal, published in English, bimonthly on the last day of even number months, and indexed in Biosys Preview, SCIE, and CABI. The journal is devoted for the publication of original research papers and review articles related to vegetables, fruits, ornamental and herbal plants, and covers all aspects of physiology, molecular biology, biotechnology, protected cultivation, postharvest technology, and research in plants related to environment.
