Fraunhofer LeTID Test Confirms Top Quality of IBC SOLAR Modules

Fraunhofer LeTID Test Confirms Top Quality of IBC SOLAR Modules
IBC SOLAR, a leading global provider of photovoltaics (PV) and energy storage, impresses with its own-brand modules in a LeTID test conducted by the Fraunhofer Center for Silicon Photovoltaics CSP. Specifically, the research institution examined the loss of power of the solar modules in the event of sustained strong incidence of light or high temperatures. All of the IBC SOLAR modules selected by Fraunhofer CSP are characterised by very low degradation and completed the test procedure with excellent results.
 
At the end of last year, Fraunhofer CSP examined all current IBC SOLAR module types with regards to susceptibility to "Light and elevated Temperature Induced Degradation (LeTID)". In the process, IBC SOLAR modules received a quality certificate for excellent LeTID stability. LeTID is triggered by excess charge carriers caused either by illumination or by electric current at temperatures above 50°C. In susceptible modules, this leads to a power loss of up to 10 percent, affecting PERC solar cells in particular. At the Fraunhofer Center, this susceptibility to degradation has been intensively researched in recent years. For further information see the IDTechEx report on Energy Harvesting Microwatt to Gigawatt: Opportunities 2020-2040.
 
 
For the current investigation, Fraunhofer CSP randomly selected four PERC modules each from IBC SOLAR's own brand. In the course of the test, the modules were exposed to different conditions and temperatures in a climate chamber over a longer period of time. In order to simulate the most realistic environmental conditions possible for the continuous use of PERC modules, the module temperature must be at least 75°C and the humidity must be 10 percent, while the modules are subjected to a defined current flow. The minimum test time is 324 hours (approximately 2 weeks). IBC SOLAR's PERC modules withstood the extreme conditions and performed with a particularly low power loss. This result proves the very low degradation that IBC SOLAR's own brand modules exhibit over their entire lifetime.
 
"We are very pleased with this excellent result,ʺ commented Stefan Horstmann, COO of IBC SOLAR AG. "Quality is more than just a promise for us. The outstanding performance of our modules not only reflects our corporate philosophy, but also proves that our extensive quality assurance measures for our own brands are paying off," he adds.
 
ʺIt is always gratifying when modules perform so well in our tests, as in the case for IBC SOLAR. Compliance with global quality standards is of great importance, as is the careful testing of the various modules,ʺ says Dr. Bengt Jäckel, head of the Modules, Components and Manufacturing Group at Fraunhofer CSP.
 
 
The globally valid test specification IEC TS 63342, which IBC SOLAR was involved in developing at an early stage, serves as the basis for the test. The main concern of all those involved was and is to ensure long-term quality standards in the photovoltaic sector.
