摘要

The present work investigates electrical energy production utilizing a quasi-solid-state device including freshwater live green macroalgae. The bio-photovoltaic device has been developed utilizing filamentous macroalgae as the primary photoactive component. These filamentous algae, which are part of the green algae family, typically thrive at the bottom of water bodies or present at the surface forming a dense layer on aquatic environments. These algae have been harvested from a nearby pond and transformed to create a biofilm. The bio-photovoltaic device was assembled by incorporating this algal biofilm in between counter electrode platinum (Pt), and photoanode consists of titanium oxide (TiO2) layer which was drop casted over fluorine-doped tin oxide (FTO) glass substrates. This fabricated device demonstrated significant generation of photo-generated current and voltage when exposed to solar illumination, indicating its potential for harnessing solar energy effectively. The optimized device (area: 1 cm × 1 cm) exhibit an open-circuit photovoltage of ~ 0.82 V on the irradiance of white light (100 mW/cm2). The device studies were also performed in the different wavelength of light source. At zero bias voltage, the device showcases a highest photo-current of 53 µA at 365 nm wavelength of incident light.
