Abstract

In Part 1 of our article, we presented a method to quantify the incidence angle modifier (IAM) of photovoltaic (PV) devices, which differs from the methods proposed in IEC 61853-2 through the following: it utilizes a spot-area irradiation, delivered by an optical fiber system, a customized angle probe holder, and a current-to-voltage converter. Part 1 focused on single-cell devices and presented the validation of the new method on two different cell architectures. In Part 2, we generalize that method to commercial-size silicon PV modules, mirroring by the approach already used for module-level spectral responsivity measurements described in IEC 60904-8:2014. The proposed method is motivated by inclusion in the currently ongoing revision of IEC 61853-2, providing research centers and testing laboratories with an additional option to perform IAM measurements indoors. The reproducibility of the proposed method is addressed in this work via interlaboratory comparison with a different measurement method for the same quantity and with a detailed uncertainty analysis.

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.
