DESIGN AND DEVELOP SOLAR CELLS.

Abstract

The photovoltages of solutions of chlorophyll and a donor or acceptor were measured for several systems. The effect of oxygen dissolved in the solvent was also investigated. The photovoltages were usually on the order of a few millivolts. In solid-lamellar systems consisting of chlorophyll and organic substrates the photovoltages were generally higher. An 'action' spectrum indicated that the peak voltage occurred at the peak absorption in the red band. Photovoltage production in the solid systems was attributed to a bi-excitonic mechanism. Quantum mechanical tunneling and other conduction mechanisms were investigated in thin films of chlorophyll a. (Author)
