Abstract Outstanding improvement in power conversion efficiency (PCE) over 25% a very short period and promising research developments to reach the theoretical PCE limit of single junction solar cells, 33%, enables organic–inorganic perovskite cells (OIPSCs) gain much attention scientific industrial community. The simplicity production OIPSCs from precursor solution either on rigid or flexible substrates makes them even more attractive for low-cost roll-to-roll processes. Though show as such higher with simple processing methods, there are still unresolved issues, while attempts made commercialize these cells. Among major problems is instability photoactive layer at interface charge transport layers /or electrodes during prolonged exposure moisture, heat radiation. To achieve matched stability, several techniques molecular interfacial engineering components have been applied. Moreover, recent times, additives, solvents, surface passivation, structural tuning developed reduce defects large grain boundaries and/or films. Under this review, we shown recently additives passivation strategies, which strongly focused enhance long-term stability simultaneously.
