Fabrication of a set of robust, highefficiency concentrator photovoltaic (cpv) modules for continuous longterm outdoor operation. to investigate the effect of spectral response on energy yield over the period of a year, two sets of small cpv modules will be fabricated that will each contain a different type of photovoltaic cells with a.
The outdoor evaluation results clearly show that the high energy yield, within the range of 1600–1700 kwhkw p and performance results of the different pv systems installed in cyprus compared to the same systems in stuttgart, provide strong evidence that such technologies can have a major impact on the future energy mix of countries with a high solar resource.
The values are normalised to kw p with the nameplate power. 4.3. comparison of performance with germany. the high potential of pv in cyprus is obvious when comparing data between the two test sites. in stuttgart the average annual yield was 1194 kwhk w p rated compared to 1580 kwhk w p rated in nicosia.
In the case of csi technologies an increase in efficiency at high am and clear sky conditions has been reported (king et al., 2004, zdanowicz et al., 2003), while other investigations performed on csi modules mounted on a tracker under clear sky conditions showed a slight decrease in performance with increasing am (kenny et al., 2006). cdte.
Finally, we model the tandem module performance using a ray optic simulationbased multiphysics model and forecast a pathway for high efficiency tandem lscsi module performance. ab we report the design, fabrication and outdoor characterization of a tandem luminescent solar concentratorsi multijunction photovoltaic module.
