In biobased solar cells, the ability of biomaterials used to absorb solar rays in red and near infrared spectral ranges and to generate photocurrents thanks to electron transfer. A solar cell is an electronic device used to convert solar energy to electricity and produces both a current and a voltage to generate electric power.
Therefore, a novel technology, the biological solar cells with high conversion efficiency and low cost was devised. The biological solar cells are a kind of natural technology which generates clean energy by making use of oxygenic photoautotrophs. The photosynthetic fractions harvest sunlight and convert it directly to electrical energy.
Some of parameters to consider when selection of an ideal biomaterial to be used in biobased solar cell include; existing functional groups, chemical (covalent) and physical bonds, the number of conjugated double π-bonds (n) and the length of the organic hydrocarbon structure chain.
Biological photovoltaic devices are a type of biological electrochemical system, or microbial fuel cell, and are sometimes also called photo-microbial fuel cells or “living solar cells”. In a biological photovoltaic system, electrons generated by photolysis of water are transferred to an anode.
Solar cells are kind of photovoltaic tool which creates voltage on exposure to sunlight because the material used in PVC is a semiconductor. Solar cells are fundamental units of PV devices, modules, and panels.
A bioreplication of arrays of insect corneas as a collector layer have been used on solar cells. These bioreplicated solar cells have the large angle of view, antireflection (AR) and hydrophobic properties (Martın Palma and Lakhtakia, 2017).
