Abstract
Among emerging materials, perovskite solar cells (PSCs) have attracted significant interest due to their high efficiency in laboratory settings. However, their performance under real outdoor environments remains insufficiently explored, largely because of the limited availability of perovskite module technology and the bulky, complex, and costly nature of conventional characterization equipment. This study presents a compact, cost-effective I–V tracer designed for both indoor and outdoor PSCs characterization. The device offers accuracy comparable to laboratory instruments, enabling comprehensive performance evaluation. It extracts key parameters from I–V curves, including open-circuit voltage (VOC), short-circuit current (ISC), maximum power point voltage (VMPP), maximum power point current (IMPP), fill factor (FF), and the power conversion efficiency (PCE), supporting sweeps from VOC to ISC and vice versa. It accommodates VOC up to 3 V and ISC up to 60 mA. Additionally, the system integrates environmental sensors to monitor solar irradiance (G), cell temperature (TPV), ambient temperature (TA), and humidity (HA), facilitating precise outdoor performance analysis. Experimental validation confirms its accuracy and reliability across various conditions, bridging the gap between laboratory testing and real-world PSCs assessment.
期刊介绍:
The IEEE Journal of Photovoltaics is a peer-reviewed, archival publication reporting original and significant research results that advance the field of photovoltaics (PV). The PV field is diverse in its science base ranging from semiconductor and PV device physics to optics and the materials sciences. The journal publishes articles that connect this science base to PV science and technology. The intent is to publish original research results that are of primary interest to the photovoltaic specialist. The scope of the IEEE J. Photovoltaics incorporates: fundamentals and new concepts of PV conversion, including those based on nanostructured materials, low-dimensional physics, multiple charge generation, up/down converters, thermophotovoltaics, hot-carrier effects, plasmonics, metamorphic materials, luminescent concentrators, and rectennas; Si-based PV, including new cell designs, crystalline and non-crystalline Si, passivation, characterization and Si crystal growth; polycrystalline, amorphous and crystalline thin-film solar cell materials, including PV structures and solar cells based on II-VI, chalcopyrite, Si and other thin film absorbers; III-V PV materials, heterostructures, multijunction devices and concentrator PV; optics for light trapping, reflection control and concentration; organic PV including polymer, hybrid and dye sensitized solar cells; space PV including cell materials and PV devices, defects and reliability, environmental effects and protective materials; PV modeling and characterization methods; and other aspects of PV, including modules, power conditioning, inverters, balance-of-systems components, monitoring, analyses and simulations, and supporting PV module standards and measurements. Tutorial and review papers on these subjects are also published and occasionally special issues are published to treat particular areas in more depth and breadth.
