PRINTED SOLAR PANEL

A solar panel can include a substrate with layers of droplets of different materials disposed on a surface of the substrate. An outer layer can be disposed away from the surface and can comprise a face of the solar panel. The layers can comprise a cathode electrode and an anode electrode disposed between the outer layer and the surface of the substrate. The layers can further comprise a P region and an N region. The P region can be disposed at least partially around the anode electrode. The N region can be disposed at least partially around the P region and at least partially around the cathode electrode. The P region and the N region can comprise droplets of a P material comprising P-doped semiconductor particles and an N material comprising N-doped semiconductor particles respectively.
