Photosystem (PSII)-based hybrid nanococktails for the fabrication of BIO-DSSC and photo-induced memory device

Abstract

Chromophore-containing complexes and proteins in nature are widespread use in the area of photochemistry and as models for photosynthesis. However, when they are removed from their biological environment, the proteins undergo denaturation and are unstable. In addition, cofactors such as NADH need to be released for continuous use in the system. In order to make PSII composed of protein mixtures, chromoforms and different cofactors stable and sustainable, the use of the ANADOLUCA (Amino Acid monomer Decorated and Light Underpinning Conjugation Approach) method to combine multicomponent photo-active bio-complexes has been used for energy and bio-inspired devices. The fabricated PSII-BNC based bio-nanodevice has boosted excellently photo-induced memory functions. To determine the stability of the particles, oxidation, reduction and OCPA potentials behavior of the PSII-BNC having a film under the light has been repeated continuously up to 10(9) cycles. In addition, we have developed a novel, bio-inspired and hybrid bio-dye-approach (BIO-H-DSSC) as a new generation of dye-sensitized solar cells. The bio-nanoenergetic layer formed by PSII-BNC with TiO2 has resulted in 0.22 % level of power conversion efficiency with open circuit voltage of 0.50 V, short circuit current of 888 mu Acm(-2) and fill factor of 0.50.
