The optical gain due to optical coupling becomes less relevant for a cell with an efficient light-trapping texture and ARC. The requirements for PV module encapsulants in terms of optimizing module efficiency can be divided into five categories: electric yield, electrical safety, reliability, module processing and cost.
Importance of PV Module Packaging -- • High module reliability for 20-30 year service life • “Packaging is the predominant cause of failure in modules” – remark of a DOE SETP PV Program reviewer, 2006
Conclusions Proper selection and initial tests of encapsulation materials are important. Different encapsulant formulations (e.g., EVA) give different quality and performance. Encapsulation method and processing conditions can affect the laminate quality and reliability of PV modules.
• High module reliability for 20-30 year service life • “Packaging is the predominant cause of failure in modules” – remark of a DOE SETP PV Program reviewer, 2006
Different encapsulant formulations (e.g., EVA) give different quality and performance. Encapsulation method and processing conditions can affect the laminate quality and reliability of PV modules. Adequate accelerated exposure tests can be useful to assess the performance expectation of materials and quality of processed components.
PVB is a thermoplastic polymer which has been used since the early 80s as a PV module encapsulant. It represents the second most processed encapsulation material, with similar material costs to EVA.
