Protocol for building and using a maximum power point output tracker for perovskite solar cells

We recently developed a galvanostatic maximum power point output (MPPT) algorithm for high-hysteresis perovskite solar cells (PSCs), enabling continuous and precise power tracking. Here, we present a protocol for assembling the tracker, implementing the algorithm on a microcontroller, and conducting JV scans and stabilized output power (SOP) or traditional perturb and observe (P&O) tracking for small-area photovoltaic cells. We also describe steps for collecting, storing, and plotting data and explain the device's operational modes and functions. For complete details on the use and execution of this protocol, please refer to Juarez-Perez et al.¹.
