Abstract

Highlights: The energy transfer mechanism of photosynthetic systems associated with the incident light frequency has been studied. The study of the fidelity and level spacing distribution has completed to find the frequencies with the highest transfer efficiency and the quasi-metal state. Based on the obtained results, there is a competition for energy transfer between the electric current and the phonon flux. The maximum efficiency has been observed near the red and purple spectrum of the incident light. Abstract: Bio-based materials offer new potentialities for photodetection applications due to their sensitivity, selectivity and biocompatibility. The present paper proposes an energy transfer mechanism associated with the incident light frequency. Based on the premise that the competition between the electrical current and phonon flux determines the dominant behavior, the paper reveals that the decrease in electrical current is compensated by increasing the phonon flux, and vice versa. Through simulating the internal potential difference using the metal leads, the study has focused on the difference between the electrical current and electrical potential difference. This makes it possible to determine the regions with the maximum electrical current. Furthermore, the paper investigates the efficient frequencies of the system through the fidelity, and level spacing distribution (P(s)) methods. The study indicates that the maximum efficiency is observed near the red and purple spectrum of the incident light confirmed by previous observations.
