Today’s major challenges in Photovoltaic production are the continuous optimization of solar cell efficiencies and at the same time the reduction of manufacturing costs. ISRA SOLAR VISION, a business unit of ISRA VISION AG, Darmstadt, Germany, provides the complete range of state-of-the-art high-efficiency inspection systems that enable PV manufacturers to master these challenges. With the new generation of contactless photoluminescence (PL) inspection systems, the leading supplier of best-in-class solar inspection systems has achieved another quantum leap in the high-accuracy, high-speed inspection of solar cells and wafers: SOLARSCAN-YIELDMASTER PL provides the industry’s fastest contactless photoluminescence inspection with the lowest false detection rates and the most accurate defect classification for the mass production of solar cells. The 100% contactless measurement method prevents cracks or breaks caused by electrical contacting which occur in conventional EL or PL series resistance measurements. This way, ISRA’s latest inspection technologies detects defects invisible to the human eye, leading to a significant increase in top-level yield and in a remarkable cost reduction in solar cell production. More than enough reasons for the global PV industry to apply the smart ISRA SOLAR VISION inspection solutions.
Based on the highest repeatability and detection rates the new generation of high-speed in-line YIELDMASTER PL inspection systems offers the industry’s best detection performance. Furthermore series resistance and other efficiency measurements are conducted contactless, which avoids defects (cracks, breaks, etc.) caused by electrical contacting units.
