Optimization of gain and energy conversion efficiency using front-facing photovoltaic cell luminescent solar concentratordesign

A comparison of performance of flat and bent photovoltaic luminescent solar concentrators

“…Experiences with LSC-PV in a product context are limited and design issues with this PV technology may be different than with conventional solar cells in PIPV (Apostolou and Reinders, 2014). In particular, geometric modifications and efficiency Chatten et al, 2011;Corrado et al, 2013;Inman et al, 2011;McIntosh et al, 2007;Pravettoni et al, 2009) play a role with regards to product-integrated LSC-PV. To evaluate these aspects (Viswanathan et al, 2012), this paper explores the effect of integration on the energy performance of LSC-PV in a light pole for outdoor lighting, like the one shown in Fig.…”

“…Specifically, the PV cells have been moved from the edges to the back of a LSC-PV element (Corrado et al, 2013), which is a new location compared to conventional flat LSC-PV elements, mirrors have been placed on the non-covered edges, a diffuser reflective sheet made of micro cellular polyethylene terephthalate (MCPET) has been attached at the back of the LSC lightguide (in between the cells), and the shape has been altered from flat to a (half-)bent cylindrical LSC-PV. The device structure is illustrated by Fig.…”

Application of concentrating luminescent down-shifting structures to CdS/CdTe solar cells with poor short wavelength response

“…1(a) are normally edge mounted, bottom mounted configurations similar to LDS have also been proposed [23] and have been investigated for increasing the performance of cSi solar cells [24][25] [26] [27]. In [28] a bottom mounted LSC was considered when calculating the efficiency limit of LSCs coupled to solar cells of different band gaps.…”

“…The advantage of such a configuration is that it ensures that concentration onto the solar cell acts to augment the performance of directly excited solar cells. It has also been suggested that these devices could be suitable for building integrated systems and recent calculations indicate a reduction in the cost/watt of such systems coupled to cSi to be around 28% [27]. The concept of LDS and bottom mounted LSCs is extended one step further and the application of concentrating luminescent down-shifting structures (C-LDS) that simultaneously improve the short wavelength response of CdS/CdTe solar cells and also concentrate light is proposed.…”

Luminescent solar concentrators with a bottom-mounted photovoltaic cell: performance optimization and power gain analysis

“…Recently, the BM-LSCs have been attracted increasing interest. Corrado et al [18] designed and fabricated a kind of thin film BM-LSCs and investigated the influencing factors, including the thickness of the waveguide, edge treatment of the window, cell width, and cell placement. A highest PCE of 6.8% was obtained with PV cell coverage of 31%.…”
