“…Moreover, analytical models tend to be considerably less computationally expensive when it comes to radiation simulation [24,32], and that is a crucial feature for real-time interactive modelling for design purposes. Tina and Scandura [34], Bahaidarah et al [5], Kostić et al [20], Reis et al [27], analytically modelled radiation for V-Trough applications, but with formulations that are over-simplified and not oriented towards a deeper step-by-step geometrical analysis. Fraidenraich [13,14] and Hermenean et al [18] developed more detailed analytical models of beam radiation for V-Trough solar devices, but the authors of this work believe that a more intuitive and design-oriented analytical model can be developed, going further into the exploration towards design insights, and with a higher flexibility in the selection of geometrical and tracking parameters.…”

In the urge to make solar energy competitive enough to directly face fossil fuels, several approaches result crucial for their intended capacity to maximise the energy that can be produced with a given photovoltaic area. Low Concentration Photovoltaics (LCPV) and tracking methods can be integrated in V-Trough solar devices to increase their effective solar harvesting area through low-cost non-imaging optics. As a tool to support the design and simulation of such devices, this work proposes an analytical and numerical model that simulates the interactions of direct solar radiation with the V-Trough's elements. The proposed model is design-oriented and was developed seeking high parameter flexibility, high geometrical detail and low computational demands. The model was experimentally validated through several simulations of V-Trough set-ups which results were compared against measurements with a testing platform. Through a non-parametric statistical analysis, the model proved to be satisfactory and highly accurate. Furthermore, the calculations regarding optical concentration performance were complemented with a cost analysis and integrated into a cost-effectiveness index. The results from this work serve as a useful modelling tool for designing and comparing alternatives of V-Trough solar devices.

“…Results indicated that concentration ratio increases with the increase in incidence angle and the tracking step duration does not affect the reflected radiation. Regarding the V-trough reflectors, many studies are referred to one or two tracking axis using flat mirrors [17][18][19][20]. System performance can be enhanced by increasing the concentration ratio, but if it reaches beyond a critical value, cooling of the panel needs to be carried out.…”

Abstract:The objective of this study was to achieve higher efficiency of a PV system while reducing of the cost of energy generation. Concentration photovoltaics was employed in the present case as it uses low cost reflectors to enhance the efficiency of the PV system and simultaneously reduces the cost of electricity generation. For this purpose a V-trough integrated with the PV system was employed for low concentration photovoltaic (LCPV). Since the electrical output of the concentrating PV system is significantly affected by the temperature of the PV cells, the motivation of the research also included studying the ability to actively cool PV cells to achieve the maximum benefit. The optical, thermal and electrical performance of the V-trough PV system was theoretically modeled and validated with experimental results. Optical modeling of V-trough was carried out to estimate the amount of enhanced absorbed radiation. Due to increase in the absorbed radiation the module temperature was also increased which was predicted by thermal model. Active cooling techniques were studied and the effect of cooling was analyzed on the performance of V-trough PV system. With absorbed radiation and module temperature as input parameters, electrical modeling was carried out and the maximum power was estimated. For the V-trough OPEN ACCESSEnergies 2015, 8 2804 PV system, experiments were performed for validating the numerical models and very good agreement was found between the two.

“…Tracking systems are usually associated to concentrator systems to assure a homogeneous illumination pattern on the cells. This measure is important to avoid mismatch losses, damage of modules by creation of hotspots or other ways [5]. The association of the reflectors along with the solar tracking system is known as the "Double Sun" technology.…”

Quantum dot (QD) solar cells have the potential to utilize the high energy photon to multiple electron-hole pairs in order to increase the maximum attainable thermodynamic conversion efficiency. It has a tunable band edge, which offers the possibility to harvest light energy over the appropriate range of light to harness the maximum efficiency of solar cell. In addition to that, integration of efficient tracking of sun using Double Sun technology results in considerable increase of power output; in effect, making better utilization of solar energy. In the present work, we demonstrated the structure and operation of double sun solar system and proposed a way of improving device performance using Q-dot nanocrystals.
