A new algorithm for the maximum power point tracking (MPPT) method has been developed in order to determine the maximum power (Pmax) for slow-responding metastable PV devices such as perovskite solar cells (PSCs). It is well known that such devices often cause significant Pmax oscillation during a standard MPPT measurement. This oscillation was found to occur caused by difference in the current acquired after increasing the voltage and that acquired after decreasing the voltage. The new algorithm developed in this paper has eliminated such oscillation with comparison between the powers at different voltages after changing the voltage in the same direction. Pmax data determined by using this algorithm were found to be reliable by comparing with those determined by the dynamic I-V measurements.
