The photosystem in green bacteria consists of a light-harvesting antenna called a chlorosome and a reaction center. The energy of the light the pigments absorb is transferred to the reaction center (red) through a protein-pigment antenna complex called the baseplate (gold). The antenna (green) is made of rod-shaped aggregates of pigment molecules.

Sometimes when people talk about solar energy, they tacitly assume that we’re stuck with some version of the silicon solar cell and its technical and cost limitations. Not so…
