The commercialization of perovskite solar cells (PSCs) has been a subject of intense research, with a significant focus on improving their long-term stability. One of the critical challenges PSCs face is their susceptibility to degradation from moisture and oxygen. Guanidinium Iodide (GAI) has emerged as a promising additive that significantly enhances the environmental stability of these devices. NINGBO INNO PHARMCHEM CO.,LTD. is at the forefront of supplying high-quality GAI to facilitate this advancement.

Research indicates that GAI plays a pivotal role in improving the water stability of perovskite films. When GAI is applied as a pretreatment or additive, it alters the surface properties of the perovskite layer. Studies have shown that GAI-treated films exhibit a higher contact angle, indicating increased hydrophobicity. This means that water molecules are less likely to adhere to or penetrate the perovskite layer, thereby reducing the rate of hydrolytic degradation. By creating a more robust barrier against moisture, GAI significantly extends the operational lifetime of PSCs, even when they are not fully encapsulated.

Beyond hydrophobicity, GAI contributes to stability by mitigating defect formation and improving the overall structural integrity of the perovskite film. The passivation of defects, as discussed previously, not only boosts efficiency but also creates a more stable crystalline structure that is less prone to degradation pathways. The controlled crystallization process induced by GAI can lead to more compact and pinhole-free films, further protecting the underlying layers from environmental stressors.

The practical implications of GAI-enhanced stability are substantial. Devices treated with GAI have demonstrated superior performance retention over extended periods in both ambient and high-humidity conditions compared to their untreated counterparts. This improved durability is a critical step towards meeting the rigorous demands of real-world applications. As the solar industry seeks reliable and long-lasting renewable energy solutions, the role of materials like Guanidinium Iodide in bolstering the stability of perovskite solar cells becomes increasingly vital.
