Sustained power output from an algal biophotovoltaic (BPV) platform using selected marine and freshwater microalgae

The global community has begun tackling the grave repercussions of excessive use of fossil fuels by strategizing co-usage of renewable and non-renewable energy sources as major energy providers. Recently, biomass feedstocks including microalgae are gaining recognition as crucial energy providers to...

description The global community has begun tackling the grave repercussions of excessive use of fossil fuels by strategizing co-usage of renewable and non-renewable energy sources as major energy providers. Recently, biomass feedstocks including microalgae are gaining recognition as crucial energy providers to cope with the demands of the fast expanding economic and social sectors. Algae, known as one of the most photosynthetically efficient organisms, are amenable to growth on a variety of substrates, and are tolerant towards extreme conditions. The integration of microalgae into photovoltaic platforms is an innovative energy provisioning technique for low-power appliances and circuits.
