Photovoltaic modules are the most important component of a photovoltaic power plant, and their reliability plays a vital role in the stability and service life of the entire system. Therefore, it is particularly necessary to conduct reliability test of photovoltaic modules. One of the important assessment points for reliability is the photostability test. After light induced degradation, the electrical properties of photovoltaic modules may vary greatly, causing abnormal output curves of photovoltaic modules, and may even lead to early failure of photovoltaic modules. Therefore, photovoltaic module LID has become an important item to evaluate the quality of photovoltaic modules. Photostability Chamber from Millennial Solar provides you with quality assurance during your production process.

Light Induced Degradation (LID) Test

Light Induced Degradation (LID) refers to the phenomenon that the output power of silicon-based thin-film photovoltaic modules decreases significantly and then stabilizes under the influence of early light factors. LID is mainly found in silicon solar panels, especially PERC modules. Devastating losses in power conversion and generation can occur due to recombination activity defects during illumination additional carrier injection.

LID is an important method for quality control of solar cell modules, which can evaluate the long-term stability of the module and ensure the performance of photovoltaic modules throughout the product life cycle. Only by establishing a trusting relationship between production plants and customers can the long-term stability and reliability of solar modules be ensured, while also contributing to environmental protection.

Introduction:

The Millennial Photostability Chamber uses xenon arc lamps that can simulate the full sunlight spectrum to reproduce destructive light waves that exist in different environments. It can provide corresponding environmental simulation and accelerated testing for photovoltaic cell product development and quality control.

Fulfill the standard:

It meets the stability test specified in the MQT09 and MQT19 provisions of the IEC61215 standard. The spot area reaches 1200*1000mm, and the spectrum meets the BBA standard.

Features:

It can be used for change tests to improve the existing process of cells or to evaluate the durability of cells after changes in composition. It can well simulate the changes caused by exposure of cells to sunlight under different environmental conditions.

•Spectral mismatch, irradiation non-uniformity, and irradiation instability must meet at least BBA level standards.

•Irradiance control mode, can be adjusted manually or automatically

•Touch screen control, you can set the temperature, running time, and cumulative radiation intensity parameters; when the running time/cumulative radiation amount is reached, the equipment automatically stops

Millennial Photostability Chamber is used with Current Continuity Monitoring System:

● ME-PV-CCD is specially developed for clauses 10.11 and 10.12 of the IEC61215 standard.

● Provides stable DC power, current recording, temperature recording and temperature control functions

● Through temperature control of the DC power supply, long-term real-time monitoring of multiple currents and temperatures

● Determine the material fatigue resistance, lamination process, welding quality, etc. of solar modules in high and low temperature alternating environments.

At present, crystalline silicon solar cells are the main body of photovoltaic power generation, and the phenomenon of light induced degradation in crystalline silicon solar cells has become an important factor restricting the development of high-efficiency solar cells. To detect light induced degradation of photovoltaic modules, Millennial Photostability Chamber is a very ideal choice. Millennial Solar strictly abides by the testing standards and protocols specified by authoritative organizations to ensure that the nominal power of the panels is equal to the actual power output, leading the progress and upgrade of the photovoltaic industry.
