非常规光伏器件中能量收集性能评估的统计方法

Abstract Results of long-term monitoring of the energy harvesting trends in field-installed large area luminescent solar concentrator based windows are reported. The main features and materials-related aspects of these unconventional, window-integrated photovoltaics are described, together with the laboratory techniques used to rate their performance. New statistical methods suitable for benchmarking the season-dependent and design-dependent field performance characteristics are described. Key performance differences between conventional and LSC based photovoltaics are identified using long-term observational datasets. Experimental results show that windows equipped with 3D structured PV modules and fluorescent polymer interlayers often feature higher energy yield stability in adverse weather conditions compared to roof-mounted silicon panels. A new parameter proposed for the quantification of the energy yield stability reveals strong advantages of the wall-mounted and mixed-orientation window-integrated PV over the conventional roof-mounted systems. The datasets also reveal correlations between the energy yield performance and window design types. The proposed data analysis methods are expected to help identify the best material combinations for use in commercial-size LSCs, complementing the standard lab assessments made using small-area samples.
