On the Power‐Characteristics of Electrochemical Solar Cells

Abstract

Abstract The output‐power‐characteristics of an electrochemical solar cell are analysed. Up to 9.5% efficiency with reference to the spectrum of a Xenon lamp has been reached with a CdS/[Fe(CN) 6 ] 3‐/4‐ ‐electrolyte cell which is equivalent to 5.5% efficiency for solar radiation. It is shown that the polarisation of the inert counter electrode and the semiconductor electrode has a critical influence on the efficiency and can lead to great losses.
