“…It is known that some errors in the measurement of PV devices can be made, since there is a mismatch in the spectral irradiance between a "reference Sun" and natural sunlight [10,11]. Therefore, more differences between the employed spectra and the reference spectra make the quality and precision of PV performance measurements worse.…”

Sun Simulators: Development of an Innovative Low Cost Film Filter

Sun simulators are employed to test the performance of photovoltaic (PV) devices, according to the standard International Electrotechnical Commission (IEC) 61215. Economical and technical analysis show that PV manufacturers need to integrate Sun simulators in the production process and, in particular, at the end of the production chain in order to measure the I-V curve and to evaluate the peak power of PV devices. Sun simulators need specific lamps to simulate the solar spectrum and a specific filter to simulate atmosphere absorbance. Such a filter can cost over €6 per square centimeter. The aim of this work is to develop an alternative filter. In particular, both chemical analysis and spectrophotometric measurements are carried out to evaluate if the Air Mass (AM) 1.5 G filter can be replaced by a cheaper material. Preliminary simulations show how specific compounds coated on a glass surface can absorb the Sun spectrum, such as the AM 1.5 filter, but with lower costs.

“…The spectral output of the lamp was filtered using Schott K113 Tempax sunlight filter (Pr€ azisions Glas & Optik GmbH, Germany) to reduce light mismatch between AM 1.5G and the simulated illumination to less than 2%. 47 JÀV measurements were taken using a Keithley 2400 sourcemeter (Keithley, U.S.A.) by independently applying external voltage to the cell and measuring the photogenerated current. The size of the mask used to test the cells was 0.25 cm 2 .…”

High-Efficiency Dye-Sensitized Solar Cell with Three-Dimensional Photoanode

et al. 2011

Herein, we present a straightforward bottom-up synthesis of a high electron mobility and highly light scattering macroporous photoanode for dye-sensitized solar cells. The dense three-dimensional Al/ZnO, SnO 2 , or TiO 2 host integrates a conformal passivation thin film to reduce recombination and a large surfacearea mesoporous anatase guest for high dye loading. This novel photoanode is designed to improve the charge extraction resulting in higher fill factor and photovoltage for DSCs. An increase in photovoltage of up to 110 mV over state-of-the-art DSC is demonstrated.

Abstract:The advantages of OPV (organic photovoltaic) are low cost, little pollution and flexible. But challenge for OPV manufacture still is lacking of accurately performance measurement due to capacitance issue. Firstly, characterization of OPV requires considering the slowly temporal response due to capacitance effect, and the relative I-V (current-voltage) curves are strongly dependent on the voltage sweep direction, even for the sweep time only in few seconds or less. Secondly, the IPCE (incident photon-to-electron conversion efficiency) also shows the slowly temporal response due to capacitance effect and is dependent on the wavelength of the incident light. Furthermore, the related features for measuring I-V curves are more sensitive with temperature due to non-linear characteristics issue, but current IPCE spectra of OPV are similar to that happened in conventional crystalline Si or amorphous silicon devices. In this work, we developed a RTOSM (real-time one-sweep method) applied both in I-V and IPCE to analysis different electronic transport materials, and result showed this new approach proposed a good way to slow down testing time and having better accuracy for OPV measurement by eliminating acceptance effect instantly.
