Analysis and Performance Improvement of Cells and Modules

Given that PV modules have diverse applications, it is essential to assess their performance outside controlled laboratory environments. Recognizing this, the industry is currently drafting a series of new IEC standards in this field, and EnergyVille is actively involved in this process. We possess a unique large-scale module tester with LED lighting, allowing us to illuminate both the front and back of large PV modules. Spectral and light intensity variations can be fully adjusted to realistically simulate outdoor conditions.

Additionally, we have test setups in both rack and facade configurations outdoors, complementing our indoor measurements. These setups enable us to precisely measure PV module voltage at small time intervals. Combined with extensive meteorological measurements, we have excellent resources for building-integrated PV research, reliability, and energy yield simulations and predictions. We ensure that both industrial and small setups can be measured in our characterization tools, with a focus on exploring new materials and technologies.

Our research on cell, material, and reliability characterization is supported by a wide variety of opto-electrical characterization tools (e.g., spectral response, reflectivity mapping, spectroscopy, high-resolution electroluminescence) and material analysis tools (e.g., optical and electron microscopy, cross-section preparation tool, adhesion tester). The combination of these extensive characterization capabilities and insights from our experts enables us to understand the causes of reduced module performance and devise roadmaps to enhance their performance.
