Spectral Changes by Dye Sensitized Solar Modules Influence the Pigment Composition and Productivity of <i>Arthrospira maxima</i> and Increase the Overall Energy Efficiency

Abstract The integration of semi‐transparent photovoltaics (PVs) with photobioreactors (PBRs) is a promising strategy to increase photoconversion efficiency, ensuring simultaneous electricity and algal biomass production. In this study, Arthrospira maxima cultivated in an integrated system dye‐sensitized solar module (DSSM) the front PBR assess possible advantages for phycocyanin application DSSM does not influence production, remarkable advantage producing additional electric energy. However, acclimation pigment observed, as causes change transmitted light spectrum. Further experiments are conducted investigate effect quality using monochromatic light‐emitting diodes (LEDs) controls. Phycocyanin‐targeted wavelengths exhibit major impact on growth productivity: low intensity enhanced process suggesting that preferable enhance culture performance respect white light. third‐generation PVs only potentially advantageous if transmission spectra color its aperture area carefully designed. LEDs PBRs also highlights importance properly managing operative conditions avoid energy losses.
