Abstract

Short‐circuit capacitance data, for solar cells with base resistivities in the range 0.5–90 Ω cm, indicate a junction capacitance injected carrier concentration of the order 10¹⁴ cm⁻³ at photovoltaic current densities of 25 mA/cm². This short‐circuit injected carrier concentration, which is usually assumed to be zero, is nine orders of magnitude greater than the equilibrium concentration. This condition is explained in terms of an expanded interpretation of the Shockley injection relation where the chemical potential K of the electrochemical potential, μ = K−eV, dominates injection rather than the electrostatic potential V.
