“…On the other hand, a-Si:H suffers from a performance degradation called light-induced degradation (LID) due to the Staebler-Wronski effect (SWE) [Staebler, D. L. and Wronski, C. R.,1977;Hussin et al, 2015]. It was demonstrated that a-Si:H TFPV modules are degraded mainly by the SWE effect, when compared to other TFPV technologies [Meyer and van Dyk, 2003;van Dyk et al, 2007;Radue and van Dyk, 2010;]. This degradation phenomenon is also present but is much less severe in μc-Si:H TFPV.…”

The analysis of the degradation of tandem amorphous silicon (a-Si:H) and microcrystalline silicon ( -Si:H): Micromorph thin-film photovoltaic (TFPV) modules and its impact on the output power of a PV array under outdoor long term exposure located in Jaén (Spain) is addressed in this work. Furthermore, the evolution of main solar cell model parameters is evaluated by means of parameters extraction techniques from monitored data of the PV system in real operation of work. The degradation rate and the stabilization period of micromorph TFPV modules, as well as the results of the evolution of each of the solar cell model parameters along the outdoor long-term exposure are analysed in order to gain a better understanding of changes in performance of micromorph TFPV modules and the behaviour of the output power of the PV generator.

“…Hydrolysis reactions could alter the chemical structure and therefore properties of these materials, causing significant degradation of the power characteristics of the PV cells. At photovoltaic module level, moisture can also cause degradation of other critical organic and inorganic components in the assembly, resulting in the generation of substances that can either further aggravate the water-induced degradation of the cell or chemically attack the cells and/or electrical assembly 17 . Deterioration of critical interfaces can happen, opening conduit for further harmful ingression of atmospheric components.…”

Predicting the reliability of polyisobutylene seal for photovoltaic application

et al. 2012

Polyisobutylene (PIB) or butyl rubber has been used widely in applications such as construction materials, adhesives and sealants, agricultural chemicals, medical devices, personal care products, and fuel additives. Due to the unique low gas permeability, flexibility, and excellent weathering resistance, PIB or PIB based materials are frequently employed in photovoltaic (PV) industry as sealant to protect the electrical assembly in the package as well as moisture sensitive PV cells from aggressive environments. Long term behavior of the PIB sealant within the operating temperature range of the PV devices thus becomes a critical factor to the reliability of the device. In this paper, an experimental study of the temperature dependent fatigue behavior of a PIB based joint is presented. A finite element model capturing the joint region geometry is developed and an approach to estimate lifetime is proposed.

“…Most approaches still surer from high temperature or vacuum, complex and rigorous conditions, slow growth rate with high cost, etc.. Peng et al [2] took the initiative to demonstrate simplified method for synthesizing large-area Si nanostructure without mask-free etching procedure at room temperature. The self-assembly of metallic nano-dot assistant growth of the nano-roughened crystalline Si structure has soon applied to the p-n junction [8], the photoelectrochemical cells [3] and the anti-reflection (AR) coating [4] upon solar cells.…”

“…Without nitride or oxide based passivation layer, numerous surface defects and dangling bonds [5] induce surface electron-hole recombination velocity to degrade tehe energy conversion efficiency. [6][7][8] Not long ago, Touzin et al [7] indicated that the ultra-thin Teflon-like coating with high adhesion and stability could can effectively passivate the surface and repulse the water or moisture penetration. [8] In this work, we compare the efficiency and hydrophobicity of the bared poly-Si PV cells deposited with standard SiN and ultra-thin Teflon-like films.…”

By employing the SiN and Teflon-like films as surface antireflective coatings, the sub-wavelength nano-pillar roughened poly-crystalline Si photovoltaic solar cells are characterized and compared. With 22nm-thick Teflon-like film coating, the bared Si PV cell shows filling factor and energy conversion efficiency of 0.70 and 10.89%, respectively, which are comparable with a standard cell employing standard SiN anti-reflective film to coat the bared Si PV cell. The water contact angle increases from 55 o to 92.6 o as the Teflon-like film thickness enlarges to 200 nm or larger, whereas the conversion efficiency of the Telfon-like film coated Si PV cell slightly degrades by 1.4% as compared to that of the bared Si PV cell. Lengthening the nano-roughened structure further results in a decreasing reflectance from 30% to 5% and an enhanced scattering to degrade the transmittance from 15% to 3% in visible wavelength region. The nano-pillar surface not only induces the multiple scattering to enhance the Haze and to reduce surface reflectance, but also shadows the incident light to reach the inner cell.
