Irradiation of red light (600-700 nm) by light-emitting diodes (LED) is a well-known method to enhance the productivity of microalgae. However, because the LED applied cultivation systems require additional electric power, their usefulness in mass production of microalgae is still questionable. In this study, we propose that solar converting dye films can be applied to enhance the productivity of microalgae without external electricity. Red fluorescent diketopyrrolopyrrole (DPP) dyes had capable of conversion of solar radiation from less efficient green light (500-600 nm) to more efficient red light for the photosynthesis of microalgae. Besides, the DPPs were designed to exhibit highly emissive properties in film state by aggregation-induced emission. The cultivation of chlorella vulgaris using dye coated cultivation flasks was monitored for ten days. Overall, the cultivation results confirmed that film type of dyes has beneficial effects on enhancing the productivity of microalgae. |
