Abstract
Photovoltaic based energy devices and their ability to supply sustainable energy from renewable energy sources encompasses a number of overlapping disciplinary areas. While semi-conductor physics, material fabrication and design and device engineering have substantially advanced the domain of photovoltaics considerably, the impact of bio-convergence in photovoltaics is considerably less recognised for fabricating energy harnessing materials.
An important directive in implementing solar powered energy effectively lies in enhancing the capture of solar energy while minimizing the cost of device fabrication and usage. Here, we view nature as an engineering challenge at the biological scale. In the context of biologically driven systems, efforts are being directed to understand the underlying principles that govern nature’s material inventory located within its bio-factory to mimic structural and functional features inherent to these systems. We assert that there is a need re-conceptualize the way materials are created to accelerate innovation of photovoltaics.
Herein, we draw upon parallels with synthetic approaches to help shape material characteristics to mimic some key biological / biosynthetic features such as size dependent quantum scale confinement and narrow size distribution of QDs, higher photosensitivity to the broader range of photons and their adsorption via band gap engineering as they relate to electronic transitions and energy emissions. Another important aspect to better device development is improving electrode conductance of cheaper non-conventional materials through biomimetic means.
