Martinopoulos, C. Renewable energy applications are increasing daily, and solar electricity, in the form of photovoltaics, is getting more and more important worldwide. As photovoltaics are connected both in series and in parallel, the panels are exposed to high potentials compared to the ground; thus, high voltage stress HVS occurs. The scope of this paper is to analyze experimentally the potential induced degradation PID in organic solar cells.

Potential Induced Degradation of solar cells and panels

Because it has no moving parts the major source of reliability issues in other types of electrical generating systems , a PV module's operating life is largely determined by the stability and resistance to corrosion of the materials from which it is constructed. Manufacturer's guarantees of up to 20 years indicate the quality of bulk silicon PV modules currently being produced. Nevertheless, there are several failure modes and degradation mechanisms which may reduce the power output or cause the module to fail. Nearly all of these mechanisms are related to water ingress or temperature stress. Example of PV module degradation or failure.

Potential-induced degradation PID is a potential-induced performance degradation in crystalline photovoltaic modules , caused by so-called stray currents. This effect may cause power loss of up to 30 percent. The cause of the harmful leakage currents, besides the structure of the solar cell, is the voltage of the individual photovoltaic PV modules to the ground. PID occurs mostly at negative voltage with respect to the ground potential and is accelerated by high system voltages, high temperatures, and high humidity. The term "potential-induced degradation" PID was first introduced in the English language in a published study by S.

Impact of Potential Induced Degradation on Solar PV Module

Potential-induced degradation PID has received considerable attention in recent years due to its detrimental impact on photovoltaic PV module performance under field conditions. While extensive studies have already been conducted in this area, the understanding of the PID phenomena is still incomplete and it remains a major problem in the PV industry. Herein, a critical review of the available literature is given to serve as a one-stop source for understanding the current status of PID research. This paper also aims to provide an overview of future research paths to address PID-related issues. This paper consists of three parts.

    The effect of HVS on long term stability of solar panels depending on the leakage current between solar cells and ground has been first addressed by NREL in This potential degradation mechanism is not monitored by the typical PV tests listed in IEC

    The so-called PID Potential Induced Degradation of photovoltaic panels is an effect that affects the potential of the modules with respect to the ground and that affects the power of the module by reducing it consistently over time.
