6 FAQs about [Photovoltaic panel luminescence characteristics analysis method]
Why is luminescence imaging important for PV module quality assurance?
Due to the rich and detailed information provided by luminescence imaging measurements and modern image analysis methods, luminescence imaging is becoming an increasingly important tool for PV module quality assurance in PV power plants.
Which method is used in photovoltaic (PV) applications?
In photovoltaic (PV) applications the most widely used methods are electroluminescence (EL), where an external forward bias is applied and photoluminescence (PL), where the excitation is by external illumination.
Can luminescence imaging be used to inspect solar power plants?
Several luminescence imaging methods have been developed and some of them are already routinely used to inspect solar power plants. The preferred inspection method to be used depends on the required image resolution, the defect types that need to be identified, cost, inspection throughput, technological readiness, and other factors.
What is photoluminescence imaging?
Photoluminescence (PL) imaging is a versatile technique for the characterisation of silicon samples across almost the entire photovoltaic (PV) value chain.
Is photoluminescence a quantitative method?
In 2004 quasi- steady-state photoluminescence was demonstrated as a quantitative method for measuring the injection dependent minority carrier lifetime of silicon wafers , a technique that is now used routinely at the University of New South Wales (UNSW) for process monitoring.
Which luminescence imaging applications are used in solar cell R&D?
A large number of qualitative and quantitative luminescence imaging applications are used in solar cell R&D and in production today that are based on EL imaging, on PL imaging or on contacted PL imaging with simultaneous current extraction or current injection.
