AI Article Synopsis
- Sustainable biomass production is gaining importance as a key resource for future energy needs and renewable materials, with algal beds being a promising source for biofuels and CO2 storage.
- The efficiency of algae photosynthesis relies on matching solar light with chlorophyll absorption, and spectral conversion can enhance this process.
- Using a specific phosphor (Ca0.59Sr0.40Eu0.01S) to convert green light to red light increases the growth and oxygen production rates of algae in a closed-cycle reactor with the species Haematococcus pluvialis.
Article Abstract
Sustainable biomass production is expected to be one of the major supporting pillars for future energy supply, as well as for renewable material provision. Algal beds represent an exciting resource for biomass/biofuel, fine chemicals and CO2 storage. Similar to other solar energy harvesting techniques, the efficiency of algal photosynthesis depends on the spectral overlap between solar irradiation and chloroplast absorption. Here we demonstrate that spectral conversion can be employed to significantly improve biomass growth and oxygen production rate in closed-cycle algae reactors. For this purpose, we adapt a photoluminescent phosphor of the type Ca0.59Sr0.40Eu0.01S, which enables efficient conversion of the green part of the incoming spectrum into red light to better match the Qy peak of chlorophyll b. Integration of a Ca0.59Sr0.40Eu0.01S backlight converter into a flat panel algae reactor filled with Haematococcus pluvialis as a model species results in significantly increased photosynthetic activity and algae reproduction rate.
