Understanding Potential Induced Degradation
نویسنده
چکیده
Potential Induced Degradation (PID) is an undesirable property of some solar modules. The factors that enable PID (voltage, heat and humidity) exist on all photovoltaic (PV) systems, but the effect does not occur on all or even most PV systems. According to Dr. Peter Hacke of the National Renewable Energy Laboratory (NREL), “All c-Si [crystalline silicon] modules have elements of reversible and non-reversible [PID] mechanisms. The key is to understand the extent to which modules experience these mechanisms.”

The potential of crude oil pollutant reduction by green alga Chlorella vulgaris and evaluation of the induced physiological responses
In recent years, one of the most major world concerns is environmental pollutants derived from industrial and social performances. Unfortunately, in oil productive countries such as Iran, the substance is one of the most principle environmental pollutants. In this study, the effect of crude oil on some of physiological responses of unicellular alga Chlorella vulgaris such as the rate of photosy...
متن کاملResponse of Two Indica Rice Varieties to Salt Stress
Salinity is one of the most challenging problems that adversely affects growth and development of plants. Therefore, understanding of the mechanisms that enable plants to adapt to salinity stress will ultimately help in the selection of stress tolerant cultivars for exploiting saline soils. The main objective of this study was to examine the effects of NaCl on some physiological and biochemic...
متن کاملHydrophobicity effect on oil degradation by two marine bacterial strains Alcanivorax borkumensis and Thalassolituus oleivorans
Variations on hydrophobicity were monitored in two marine obligate hydrocarbonoclastic bacteria: Alcanivorax borkumensis SK2T and Thalassolituus oleivoras MIL-1T. These strains were inoculated, separately in ONR7a mineral medium with different concentration of sodium acetate. During 10 days measurements of cellular abundance and cellular hydrophobicity (capacity to adhere at polystyrene) were c...

In this paper, analytical models for NBTI induced degradation in a P-channel triple gate MOSFET and HCI induced degradation in an N-channel bulk FinFET are presented, through solving the Reaction-Diffusion equations multi-dimensionally considering geometry dependence of this framework of equations. The new models are compared to measurement data and gives excellent results. The results interpre...
متن کاملProtective Effects of Interleukin-4 on Tissue Destruction and Morphological Changes of Bovine Nasal Chondrocytes in vitro
Background: Previous studies have shown that some cytokines have protective effects on cartilage in joint diseases. In the current study, effects of IL-4 against morphological changes and tissue degradation induced by IL-1α on bovine nasal cartilage (BNC) explants were investigated. Methods: Fresh BNC samples were prepared from a slaughterhouse under sterile conditions. BNC explants culture was...
