In the solar photovoltaic (PV) business, which is undergoing rapid development, it is of the utmost importance for manufacturers and project developers alike to guarantee the long-term dependability and performance of solar modules. Potentially Induced Degradation (PID) is a phenomenon that can have a substantial impact on the efficiency and lifespan of solar photovoltaic (PV) systems. This phenomenon is one of the most significant difficulties that the industry is currently currently experiencing. A portfolio of cutting-edge anti-PID masterbatch solutions has been created by COACE, a leading maker of revolutionary polymer additives, in order to solve this important issue. These solutions are poised to alter the way solar PV modules are designed and manufactured.

Recognizing the Possibility of Induced Material Degradation

Potential Induced Degradation (PID) is a complicated phenomenon that takes place when the voltage potential between the solar cells and the grounded module frame or other conductive elements generates an electrochemical reaction. This reaction ultimately results in the gradual degradation of the solar cells and other essential components that are contained within the PV module. This degradation can present itself in a variety of ways, including decreased power production, higher leakage currents, and even complete module failure with all of these manifestations.

PID is caused by a number of factors, the most important of which are high system voltages, increased temperatures, and the presence of moisture and ionic pollutants. These factors can form a conductive route between the solar cells and the frame of the module or other conductive materials. As the PID process moves forward, the degradation may quicken, which can result in a considerable decrease in the overall performance and dependability of the solar photovoltaic (PV) system.

Taking on the Challenge with the Anti-PID Masterbatch Solutions Offered by COACE

As a result of COACE’s recognition of the crucial relevance of mitigating PID in the solar PV sector, the company has created a comprehensive portfolio of anti-PID masterbatch solutions. These solutions are intended to improve the resilience and durability of solar PV modules. These cutting-edge products make use of the most recent advancements in polymer science and additive technology in order to offer targeted protection against the many elements that lead to PID-related conditions.

PID-Resistant Encapsulants

The anti-PID masterbatch solutions offered by COACE contain specific additives that are capable of being included into the ethylene-vinyl acetate (EVA) or other encapsulant materials that are frequently utilized in solar photovoltaic (PV) modules. Due to the fact that these additives function to improve the electrical resistance of the encapsulant, they are able to effectively reduce the flow of leakage currents and mitigate the electrochemical reactions that lead to PID.

Surface Modification Additives

In addition to addressing the encapsulant, the anti-PID masterbatch solutions offered by COACE also include surface modification additives.

These additives can be applied to the backsheet as well as other conductive surfaces that are contained within the PV module. In addition to significantly improving the module’s resilience to PID, these additives produce a protective barrier that prevents the creation of conductive channels.
Multifunctional Formulations: The anti-PID masterbatch solutions offered by COACE are designed to be multifunctional, meaning that they not only address PID but also other types of environmental degradation, such as UV radiation, thermal cycling, and moisture-induced corrosion. These masterbatch solutions provide a complete approach to improving the long-term durability and dependability of solar photovoltaic modules. This is accomplished by mixing PID-resistant additives with other protective components.

Individually Tailored Solutions

In light of the fact that every solar photovoltaic (PV) application and environment has its own set of challenges, the anti-PID masterbatch solutions offered by COACE are meant to be extremely configurable. The team of technical experts employed by the company collaborates closely with manufacturers to produce individualized formulas that cater to the particular demands and requirements of their solar photovoltaic modules. This helps to ensure that the modules receive optimal performance and have a long lifespan.
