The impact of advanced high-precision measurement technologies on the progress of mainstream PV technologies and industry development

Abstract

With the rapid advancement of photovoltaic (PV) technology, high-precision measurement techniques have become indispensable in driving progress across mainstream PV technology routes and facilitating industry upgrades. At present, HJT, TOPCon, xBC, perovskite, and tandem technologies are gradually becoming mainstream in the PV market or are entering large-scale industrialization. Compared to conventional PV devices, measuring the performance of these emerging technologies presents more complex challenges. These challenges extend beyond the elimination of hysteresis effects and encompass variations in response time, metastable behavior, nonlinearity, and spectral mismatch, all of which pose significant difficulties in the accurate measurement of power and performance parameters. These parameters are critical for evaluating cell processes and the integration of novel materials in PV modules, making them key benchmarks for technological progress and commercialization.

This report provides a detailed overview of TÜV Rheinland's application of advanced high-precision measurement techniques in the performance evaluation of PV modules, along with an in-depth analysis of performance data across various PV technology routes. These measurement techniques not only offer reliable support for design optimization and process improvements for PV manufacturers but also play a crucial role in enhancing product consistency and performance. TÜV Rheinland adheres strictly to international testing standards, ensuring the independence and impartiality of measurement data, thus increasing the credibility of the test results. By employing a range of high-precision measurement methods, TÜV Rheinland is contributing to the PV industry's evolution toward greater efficiency and reliability, supporting the global energy transition and sustainable development.
