“…This is due to the fact that over 50% of the total cost in PV system is used to purchase solar panels . The use of solar concentrators offers a solution to this problem since concentrating systems collect sunlight from a large area and focus the intensity onto a smaller area . Thus, a significant reduction is made in the cost of the PV system because the expensive PV modules are replaced by inexpensive reflector materials .…”

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.

“…Thus, a standard symmetric 2D CPC, shown in Figure 2, was designed and fabricated for this study. The constructions of the CPC profiles for this study were based on the previously reported design [1,2]. The CPC had an acceptance half-angle ( ) and entrance ( ) and exit ( ) apertures areas of 18 ∘ , 214 mm, and 66 mm, respectively, making a geometric concentration ratio ( ) of 3.24.…”

“…The evaluation of optical efficiency of a concentrating system is an important process because it is a measure of the quality of the concentrating unit [42]. On the other hand, the way in which solar radiation is incident on the surface of a concentrated PV module is vital to its performance because different nonuniform energy flux profiles have different negative effect on the electrical performance of a PV module [2]. Therefore, the first task in this investigation was to compare the angular acceptance, optical efficiency, and energy flux profiles of the CPC with and without the HRW.…”

“…The importance of cost reduction in PV concentrators originates from the fact that the optical element of the concentrating system is cheaper than purchasing additional PV modules thus leading to potential saving. However, one problem with the use of solar concentrating systems such as Compound Parabolic Concentrator (CPC) in PV application is the increase in operating PV module temperature which results in power output reduction [1][2][3]. In addition, long-time high operating PV module temperature causes irreversible PV module degradation which results in decrease in performance and PV module's lifetime [4].…”

One problem with concentrating photovoltaic systems is the increase in operating photovoltaic module temperature which results in power output reduction. Indium Tin Oxide (ITO) coated glasses exhibit both high transmittance in the visible region and high reflectance in the infrared region of the solar spectrum. Such materials can be used as selective windows in photovoltaic modules operating under concentrating system enabling passive cooling. In this paper, a Heat Reflector Window (HRW) consisting of a glass coated with 180 nm layer of ITO was experimentally tested. The ITO coated glass had a transmittance of about 85% in the visible region and over 80% reflectance in the infrared region of the solar spectrum and was placed at the exit aperture of a Compound Parabolic Concentrator (CPC). Results indicate that the temperature of a photovoltaic module under CPC with the HRW was reduced by about 50% as compared to a similar photovoltaic module with CPC but without the HRW. However, due to presence of the HRW at the exit aperture of the CPC, the photovoltaic module with the CPC and HRW received less solar irradiance compared to a similar photovoltaic module with the CPC but without HRW.

Energy generation and consumption have always been an important component of social development. Interests in this field are beginning to shift to indoor photovoltaics (IPV) which can serve as power sources under low light conditions to meet the energy needs of rapidly growing fields, such as intelligence gathering and information processing which usually operate via the Internet‐of‐things (IoT). Since the power requirements for this purpose continue to decrease, IPV systems under low light may facilitate the realization of self‐powered high‐tech electronic devices connected through the IoT. This review discusses and compares the characteristics of different types of IPV devices such as those based on silicon, dye, III‐V semiconductors, organic compounds, and halide perovskites. Among them, specific attention is paid to perovskite photovoltaics which may potentially become a high performing IPV system due to the fascinating photophysics of the halide perovskite active layer. The limitations of such indoor application as they relate to the toxicity, stability, and electronic structure of halide perovskites are also discussed. Finally, strategies which could produce highly functional, nontoxic, and stable perovskite photovoltaics devices for indoor applications are proposed.
