Leading Next-Gen PV Inspection, Empowering Perovskite Industrialization
The globally anticipated SNEC PV+ 19th (2026) International Solar Photovoltaic and Smart Energy (Shanghai) Conference & Exhibition will grandly open from June 3rd to 5th, 2026, at the National Convention and Exhibition Center (Shanghai). As a technology leader in photovoltaic (PV) testing, Wuhan YOHA Laser Technology Co., Ltd. (Sibo) is proud to announce the mysterious debut of its cutting-edge Perovskite EL+PL Tester at Booth 2.1H-D610. We warmly welcome customers, partners, and industry peers to visit, unlock the frontier black technology of PV inspection, and attend a grand technological feast.

Perovskite solar cells are rapidly emerging as the core next-generation PV technology, offering disruptive advantages such as ultra-high theoretical efficiency, low cost, and flexibility. However, their unique material properties demand high-precision, comprehensive inspection solutions. With over 20 years of expertise in PV testing, YOHA Laser has addressed this critical industry challenge by launching the YHG-ELPL Perovskite EL+PL Tester, a dedicated solution for quality control in perovskite manufacturing.
Core Technical Highlights: Setting a New Standard for Inspection
  1. Dual-Mode Fusion for Comprehensive Analysis: Integrates Electroluminescence (EL) and Photoluminescence (PL) technologies. EL imaging pinpoints electrical defects like micro-cracks, broken fingers, and poor contact that impede current flow. PL imaging enables non-contact evaluation of thin-film crystallinity, defect density, and material uniformity. This dual-mode system provides a complete quality 'check-up' from intrinsic material properties to device process defects.
  1. High-Resolution Dual-Camera, Micron-Level Precision: Features a dual-camera system (12MP telephoto + 20MP wide-angle) for full coverage from small samples to large modules. With an exceptional detection sensitivity of 50-100μm, it accurately captures micro-scale defects, ensuring zero quality risks.
  1. High Efficiency for All Scenarios: Boasts a standard 300×300mm test area (customizable) and a fast test cycle ≤10 seconds, perfectly catering to R&D, pilot, and mass production lines, balancing precision and productivity.
  1. Intelligent Software for Data-Driven Decisions: Equipped with AI-powered analysis software for automatic defect recognition, classification, and mapping. It generates intuitive defect thermal maps, providing actionable data for process optimization and yield improvement.
This SNEC exhibition marks the first global mysterious debut of YOHA Laser's revolutionary EL+PL perovskite product, embodying the company's over 20 years of technological accumulation and innovative breakthroughs in PV testing. Beyond showcasing this highly anticipated flagship equipment, we present a complete lifecycle testing solution for perovskite. We look forward to in-depth discussions with global visitors at Booth 2.1H-D610, unlocking the secrets of the new product, collaborating to accelerate the commercialization of perovskite technology and building a sustainable energy future together!
