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.

“…In addition, the use of CPC in two stage-concentrating systems has been reported to create uniform flux distribution along the PV module. [48][49][50][51][52] Another way of mitigating non-uniform illumination in PV application is the use of planar concentrators, which illuminate the receiver uniformly. [53][54][55][56] Nevertheless, the application of planar concentrators in PVs is limited by their low-concentration ratios.…”

Summary Currently, all compound parabolic concentrators (CPCs) for photovoltaic (PV) application consist of reflecting surfaces in the form of a parabolic shape. However, parabolic shapes create non‐uniform illumination on the PV module, which significantly reduces the power output. To achieve high‐concentration ratio and uniform illumination on the PV module, this study proposes the use of flat reflector sections in a symmetric two‐dimentional CPC instead of the parabolic shape. This collector is called multisectioned compound parabolic concentrator (M‐CPC). However, the main challenge in designing such a concentrating system lies in the determination of the optimal number of flat sections and the width of each section so that the optical properties of the M‐CPC approaches that of the standard CPC. In this work, seven M‐CPCs having the same designing parameters but with different total number of flat reflector sections were designed. A detailed analysis of the optical performance was undertaken to optimase the M‐CPCs. The optimal design was based on‐high angular acceptance, low‐optical losses, high‐optical efficiency in a wide‐interval incidence angles, and uniform energy flux distribution on the PV module. Results from the ray trace simulation analysis show that the optimal M‐CPC is the design with a total number of seven flat reflector sections (ie, M‐CPC7). This design has high‐angular acceptance (100%) in a wide‐interval incidence angles, low‐optical losses (7%), and high‐optical efficiency of about 95% in a wide‐interval incidence angles. In addition, M‐CPC7 illuminates the PV module more uniformly than the standard CPC.

“…In literature, non-imaging solar concentrators, particularly those having large reflective areas, are usually categorized by two types of designs based on how the optical alignment is kept during sun tracking operations; i.e. the on-axis tracking design (Chong et al, 2010(Chong et al, , 2009Siaw et al, 2014;Tan et al, 2014;Wong et al, 2015;Yew et al, 2015), and the off-axis tracking design (Chen et al, 2001(Chen et al, , 2002(Chen et al, , 2003(Chen et al, , 2005(Chen et al, , 2004(Chen et al, , 2006a(Chen et al, , 2006bRoos et al, 2007;Guo et al, 2007;Chong et al, 2010Tan, 2011, 2012;Chong, 2010aChong, , 2010b. Each type of design stands on its own merits.…”
