Title: Numerical method for angle-of-incidence correction factors for diffuse radiation incident photovoltaic modules

Abstract

Here, a numerical method is provided for solving the integral equation for the angle-of-incidence (AOI) correction factor for diffuse radiation incident photovoltaic (PV) modules. The types of diffuse radiation considered include sky, circumsolar, horizon, and ground-reflected. The method permits PV module AOI characteristics to be addressed when calculating AOI losses associated with diffuse radiation. Pseudo code is provided to aid users in the implementation, and results are shown for PV modules with tilt angles from 0° to 90°. Diffuse AOI losses are greatest for small PV module tilt angles. Including AOI losses associated with the diffuse irradiance will improve predictions of PV system performance.

  • In this study, it was investigated how changes in spectral solar radiation effects the output of photovoltaic modules. First, there was a precise examination of the seasonal changes in spectral solar radiation. Consequently, it was found that the ratio of spectral solar radiation available for solar cell utilization, to global solar radiation, changes from season to season. It varied, from 5% for polycrystalline silicon cells, to 14% for amorphous silicon cells, throughout one year. Obviously a cell made from amorphous silicon is more severely effected by seasonal variations. Next, the seasonal changes of photovoltaic module output were examined. The outputmore » was calculated by the conventional output evaluation method using irradiance and cell temperature. This calculated value and the subsequently measured value were accumulated and the two values compared. As a result, the accumulated output of photovoltaic modules was confirmed as changing seasonally in the same way as spectral solar radiation. 6 refs., 9 figs., 2 tabs.« less
  • In pole figure measurement by X-ray diffraction, the intensity must be corrected for geometric factors entering into the intensity. For the grazing (often, also called glancing) angle diffraction mode, the irradiated area changes with the grazing angle. A theoretical analysis of this effect was made and compared with measured data from a texture-free silver sample. An intensity correction factor is given as the ratio of the detector slit width and the width of the irradiated sample area as seen from the detector. As an application, the texture of thin copper film was studied.
  • The effects of the angle of incidence on the structural and photovoltaic properties of electron-beam-deposited SnO/sub 2//n-Si solar cells have been studied in detail. X-ray diffraction analyses of SnO/sub 2/ films deposited on silicon indicate the presence of multiple phases of tin oxide. A correlation is observed between the angle of incidence and x-ray diffraction pattern. The angular dependences of the short-circuit photocurrent, open-circuit photovoltage, fill factor, conductivity, and efficiency were similar. A model is proposed to explain the observed photovoltaic parameter versus angle of incidence results. In this model, the carrier ''transmission'' or tunneling probability across the interfacial SiO/submore » 2/ layer is assumed to be a function of the crystallite orientation and phases of the tin oxide.« less
  • Historically, two time-of-day dependent factors have complicated the characterization of photovoltaic module and array performance; namely, changes in the solar spectrum over the day and optical effects in the module that vary with the solar angle-of-incidence. This paper describes straightforward methods for directly measuring the effects of these two factors. Measured results for commercial modules, as well as for typical solar irradiance sensors (pyranometers) are provided. The empirical relationships obtained from the measurements can be used to improve the methods used for system design, verification of performance after installation, and diagnostic monitoring of performance during operation.
