“…It was concluded that a building integrated concentrating PV system incorporating RACPC would not only generate electricity but also minimise energy consumption by providing ambient light to building interiors. On the basis of the previous study, Abu‐Bakar et al fabricated and analysed the performance of a 3D RACPC with 3.67×. They conducted a series of indoor experiments and found that the RACPC increased the maximum power ratio by up to 3.33× when compared with similar non‐concentrating cell.…”

Summary The use of concentrating systems has been proposed as a way to reduce the cost of electrical energy from photovoltaic (PV) module. Since 1970s, different solar collector designs have been used to increase energy flux on the PV module. This study aims at providing a comprehensive review of development in the application of compound parabolic concentrators (CPCs) to solar photovoltaic conversion for the past five decades. By narrowing down the application of CPCs to electrical energy only gives a reader an opportunity to clearly understand the detail development stages, challenges, and research opportunities for further improvement. From this review, it has been found that during 1970s, all studies on the application of CPCs to solar photovoltaic conversion were mainly focused on establishing technical feasibility and cost effectiveness. Thereafter (1981‐May 2018), extensive studies were carried out to resolve challenges that were observed during the establishment stage. However, it has been found that even though the power output of the PV modules with the CPC was always higher than similar modules without the CPC, the values were less than the expected (theoretical) results. This was due to optical losses, series resistance losses, non‐uniform illumination effect, and high operating cell temperature effect. In addition, high cost of the PV‐CPC systems and low concentration ratio of the CPCs were also the main concerns of various researchers.

“…The optical efficiency resulted from simulation ranges between 94% and 98%. Abu‐Bakar et al evaluated the performance of rotationally asymmetrical CPC with GCR of 3.67, integrated with monocrystalline solar cell. Results showed an optical efficiency of 92% with an increase in I sc by 3.01 and a maximum power ratio of 3.3.…”

Summary Improving photovoltaic (PV) system power output is the main target of research in this field. Using concentrators with PV systems should increase the power output and consequently reduce the power production costs. However, using concentrators with PV (CPV) system has a drawback of a higher PV system temperature, which affects the voltage produced by the system leading to lower overall system power output. This paper experimentally investigates the performance of a polycrystalline silicon PV cell with a low‐concentration ratio square aperture concentrator. A 50 × 50 mm cell was tested without concentration and with a range of geometric concentration ratios (GCRs) of 4, 6, 8, and 10. Various cooling methods were studied, including no cooling, passive cooling by using finned heatsink, and active cooling by using finned heatsink and a fan, and the CPV performance was presented in conversion efficiency, the electrical power gain, and the reduction in PV material at various testing conditions. Significant improvement was obtained by using square aperture concentrator at different GCRs with highest power gain of 362.85%, PV cell material reduction of 78.39%, and efficiency increase by 72% at GCR 10 and active cooling. The results do not consider the power needed to extract the heat generated by the concentration and reduce the cell temperature by using air cooling. But the extracted heat enhances the CPV system output if it is harnessed in domestic applications such as water heating applications. These results highlight the potential of the developed CPV system.

“…It has been indicated in Refs [15], [16] that an LCPV system could generate not only electricity, but it has the capabilities to provide natural illumination into the building, to provide space heating and hot water generation or ventilation (depending on the heat extraction method to utilise the co-generated heat from the photovoltaic effect) which further reduces the energy consumption in a building. The RACPC-PV module can be implemented in a number of ways and could replace the windows, rooftops and building facades.…”

This paper discusses the prospect of integrating a novel type of low concentration photovoltaic (LCPV) design known as the rotationally asymmetrical compound parabolic concentrator (RACPC) in a building in the United Kingdom. This is done by proposing a number of building integration designs to create a zero carbon building. A cost reduction analysis of installing the LCPV systems in the country is also presented. It was found that an RACPC design could reduce the LCPV module's manufacturing cost by 31.75% and the LCPV module's cost per unit power output by 33.87% when compared with the conventional PV module.
