Method of Fabricating Graphane-Based Algal Biofilm Electrode for Application in A Biophotovoltac Device



The exploitation of renewable energy sources for delivering carbon neutral or carbon negative solutions has become challenging in the current era, because conventional fuel sources are of finite origins. Algae are amongst the most efficient photosynthetic organisms; amenable to growth on a wide range of substrates. Algae are being used in the development of biophotovoltaic (BPV) platforms, which are used to harvest solar energy for bioelectricity generation. In photosynthesis, a very small amount of solar energy absorbed is transformed into chemical energy, while the rest is wasted as heat and fluorescence. This energy can be harvested through biophotovoltaic (BPV) platforms to generate electrical power. The BPV incorporates a novel rGO anode coated with a film of Chlorella sp., a green microalga.  This novel BPV surpasses the traditional ITO based BPV (maximum power density of 0.124 mWm-2) in terms of relative power output by 119% (power density of 0.273 mWm-2).

The advantages:


  • Novel carbon neutral/negative energy technology
  • Produces high energy density 
  • Algae has extremely high photosynthetic efficiency 
  • Algae are fast growing
  • Algae cultivation has no conflicts with food production
  • Produces high-value chemicals (by-products)
  • Can be integrated with bioremediation of wastewaters
  • Is an economically viable bioelectricity technology
