Introduction: Recently, the use of renewable biological materials as energy storage devices has significantly developed. These tools are considered as a solution to the problem of contamination and instability with the ability to energy storage. On the other hand, the conversion of heat into power is very significant in practical applications. Accordingly, the use of a biological system as a thermocurrent and thermopower device can be very appealing.
Analysis method: In the current study, we have used a photosynthetic system, the chlorosome, to study the effect of the temperature gradient to create an electrical current. The system is irradiated and heated by laser light. To model the thermal effects of laser irradiation, we have investigated the system in the contact with a quantum thermostat. On the other hand, in order to obtain the Seebeck coefficient, we used metallic electrodes to create an electrical potential difference at the two ends of the system.
Results: The electrical current and voltage increase through the increasing the temperature gradients and can reach a maximum of nA36.6 and 0.3 V, respectively. The obtained result allows us to design and fabricate devices with 11.1 nW power. The Seebeck coefficient is ~ 41.916 mV / K, which is significantly higher than other biological systems. I-δV-δT diagram shows temperatures of 30 K and 50 K for the maximum current flowing through the system. The nearest neighbor levels distribution and the fractal dimension show that the system is stable at this temperature and voltage gradient.
Conclusion: Chromophores as absorption sources in the environment can act as a source to enhance the efficiency of absorption and conversion of the laser photon flux into an electron or phonon beam. It enables the control of the energy transfer process of the photon source in the required environments. The current study designs and engineers the photosynthetic systems based on optical sources to increase the efficiency of the laser irradiation process. The obtained electric current and the power for the system are comparable to other biological systems which demonstrate the capability of these systems as thermocurrent and thermopower devices. The Seebeck coefficient is also significantly higher than other biological systems. On the other hand, the system is stable against the light radiation-driven temperature gradient and applied voltage.
