Abstract
(EN)
The invention provides a bio-photovoltaic device, in which a photoelectric center, exemplified by a biological photosynthetic reaction center (RC), is dispersed and mobile in a medium, such as an aqueous solution. The charges generated by the illuminated RC are transferred to electrodes via one or more mediators. In selected embodiments, the difference between the reaction rates of two types of mediator at the electrode surfaces, in conjunction with other charge transfer reaction equilibria, determines the direction of the photocurrent in the device. In an exemplified embodiment, the magnitude of the photocurrent is proportional to the incident light intensity, and the current increases nonlinearly with an increase in the RC concentration in the medium.

La présente invention a trait à un dispositif bio-photovoltaïque doté d'un centre photoélectrique, illustré par un centre de réaction (RC) photosynthétique biologique, qui est dispersé et mobile dans un milieu, tel qu'une solution aqueuse. Les charges générées par le RC éclairé sont transférées à des électrodes par l'intermédiaire d'un ou de plusieurs médiateurs. Selon des modes de réalisation sélectionnés, la différence entre les vitesses de réaction de deux types de médiateur sur les surfaces d'électrode, en association avec d'autres équilibres de réaction de transfert de charge, détermine la direction du courant photoélectrique dans le dispositif. Selon un mode de réalisation donné à titre d'exemple, l'amplitude du courant photoélectrique est proportionnelle à l'intensité de la lumière incidente, et le courant augmente de façon non linéaire avec l'augmentation de la concentration du RC dans le milieu.
