In this study, we report on the calculation of interface charge distribution of metal–interlayer–semiconductor (MIS) photovoltaic diodes containing DNA biomolecules and Si semiconductor based on the conductance technique. DNA biofilms were deposited at room temperature using a simple cast method on p-type Si. Interface parameters of the Al/DNA/p-Si structures were investigated by using capacitance–voltage (C–V) and conductance–voltage (G–V) measurements as a function of frequency. The distributions of interfacial charge states and the trap relaxation times were reported. Also, photoelectric and photocapacitance properties of the diode were measured at room temperature.
