“…Therefore, the tolerance (acceptance angle) of the collector using two linear Fresnel lenses is investigated. The acceptance angle is defined as the incident angle of the sunlight at which the solar power over receiver drops to 90% of its maximum [33,34]. Figure 13 shows the tolerance of collector around 0.6 0 of the newly designed collector.…”

In this paper, we present a design and optical simulation of a daylighting system using a novel design of linear Fresnel lens, which is constructed based on the conservation of optical path length and edge ray theorem. The linear Fresnel lens can achieve a high uniformity by using a new idea of design in which each groove of the lens distributes sunlight uniformly over the receiver so that the whole lens also uniformly distributes sunlight over the receiver. In this daylighting system, the novel design of linear Fresnel lens significantly improves the uniformity of collector and distributor. Therefore, it can help to improve the performance of the daylighting system. The structure of the linear Fresnel lenses is designed by using Matlab. Then, the structure of lenses is appreciated by ray tracing in LightTools TM to find out the optimum lens shape. In addition, the simulation is performed by using LightTools TM to estimate the efficiency of the daylighting system. The results show that the designed collector can achieve the efficiency of~80% with the tolerance of~0.6 0 and the concentration ratio of 340 times, while the designed distributor can reach a high uniformity of >90%.

“…31 Other materials including InGaN 32 and InN 33 are currently being pursued, while others such as GaAsBi 34 are being considered for multijunction solar cells. One way of improving the cost-effectiveness of these very expensive but highly efficient solar cells is to use a concentrator, i.e., to harvest light over a large area but deliver it to small but very efficient solar cells 35 (e.g., planar Fresnel lenses 36 ). Another recent development deals with the application of various nanostructures to produce novel architectures for solar cells and, in some cases, to take advantage of new energy conversion physics.…”

Abstract. In celebration of the 2015 International Year of Light, we highlight major breakthroughs in photonics for energy conversion and conservation. The section on energy conversion discusses the role of light in solar light harvesting for electrical and thermal power generation; chemical energy conversion and fuel generation; as well as photonic sensors for energy applications. The section on energy conservation focuses on solid-state lighting, flat-panel displays, and optical communications and interconnects.

“…Regarding SOEs, there are a variety of different types such as refractive, reflective or both. For example, V-trough, refractive CPCs, refractive silos and hollow inverted pyramid reflectors [23,24]. Reflective SOEs are less expensive and are reasonably easier to produce compared to refractive ones.…”

This study was performed in outdoor conditions to quantify the level of influence on the electrical performance of the Multi-junction (MJ) solar cells. It was discovered that non-uniform illumination on the solar cell could reduce the MJ electrical output by more than 40%. Also, the irradiation uniformity was improved by applying several methods; increasing the distance between the concentrator and the receiver (l) and introducing a secondary optical element (SOE) on the receiver. The outdoor measurement also revealed that the electrical efficiency of the solar cell increased from around 22% to 37% with an increment of 68%, due to improvement of irradiation uniformity. However, the optical efficiency substantially fell when increasing the distance (l). To address this issue, a 0.06 m high SOE having a surface reflectivity of 90% above the PV assembly was implemented to enhance the irradiation uniformity and to minimise the dramatic decline in optical efficiency. The hot spot initiated by non-uniform illumination was also examined in outdoor conditions by measuring the temperature at the centre and both sides of the PV cell. Accordingly, a variance of about 13 K was observed between the centre and both sides (0.005 m distance) of the PV cell's surface area, which was further reduced to 1 K after improving the illumination uniformity.
