Summary An innovative dye‐sensitized solar cell based on achiote seeds with a new dual electrical generation mechanism is presented. This dye‐sensitized solar cell, in addition to the well‐known mechanism, where the conduction electrons are released from the dye molecules due to their interaction with photons, shows a distinct chemical mechanism that produces an effective electric current under dark conditions. Both mechanisms operate simultaneously; however, the electrical signal obtained from the photoelectrical mechanism is stronger. Additionally, during a rapid transition from darkness to illuminate conditions, non‐linear oscillations in the current signal are produced when the system is shifted rapidly far from equilibrium conditions.
