NOVELTY - A solar cell comprises photosynthetic molecules to absorb light energy (1) and converts the light energy into an electrical output. The cell uses photosynthetic molecules to donate electrons to electron acceptor molecules (5, 6) or directly to an electrode; or to accept electrons from electron donor molecules (11), or directly from an electrode.    USE - For converting light energy into electrical output to produce electricity.    ADVANTAGE - The device utilizes the energy-dense visible light region of the spectrum and also to convert light energy into electricity with considerably higher efficiency than photovoltaic cells currently available on the market. The device uses several types of light-absorbing molecular complexes to increase the absorbance at specific wavelengths.    DETAILED DESCRIPTION - A solar cell comprises photosynthetic molecules to absorb light energy (1) and converts the light energy into an electrical output. The cell uses photosynthetic molecules to donate electrons to electron acceptor molecules (5, 6) or directly to an electrode; or to accept electrons from electron donor molecules (11), or directly from an electrode. The device uses photosystem 1 (PS 1) complex to absorb light energy; or to donate electrons. The device uses biological electron acceptor molecules to donate electrons to the electron accepting (oxidizing) side of the PS 1 complex; or to accept electrons from the electron donating (reducing) side of the PS 1 complex. The photosynthetic molecules are embedded in a lipid membrane or in artificial membrane, suspended in the pores within some other, solid material. The photosynthetic molecules are obtained from different plant, algal or bacterial species to maximize the absorption of light at a range of different wavelengths. The device contains components in solution to maintain the stability of the photosynthetic and electron transfer molecules.
