“…The appeal of PV modules for electrical power generation stems mainly from cost and on the efficiency of energy conversion, viability, availability, and affordability. Various methods and techniques have been developed and suggested to maximize the electrical power output of PV modules using concentrated photovoltaic [67,68], hybrid solar photovoltaic/thermal (PV/T) [69,70], nanofluids [71][72][73][74][75], evaporative cooling [76][77][78][79], phase change material (PCM) [80,81], thermoelectric [82,83], etc. A combination of photovoltaic/thermal (PV/T) can be augmented into façades, windows, rooftops, and shading devices to provide both electrical and thermal energy [84].…”

Advances in building-integrated photovoltaic (BIPV) systems for residential and commercial purposes are set to minimize overall energy requirements and associated greenhouse gas emissions. The BIPV design considerations entail energy infrastructure, pertinent renewable energy sources, and energy efficiency provisions. In this work, the performance of roof/façade-based BIPV systems and the affecting parameters on cooling/heating loads of buildings are reviewed. Moreover, this work provides an overview of different categories of BIPV, presenting the recent developments and sufficient references, and supporting more successful implementations of BIPV for various globe zones. A number of available technologies decide the best selections, and make easy configuration of the BIPV, avoiding any difficulties, and allowing flexibility of design in order to adapt to local environmental conditions, and are adequate to important considerations, such as building codes, building structures and loads, architectural components, replacement and maintenance, energy resources, and all associated expenditure. The passive and active effects of both air-based and water-based BIPV systems have great effects on the cooling and heating loads and thermal comfort and, hence, on the electricity consumption.

“…[ 3 ] The inherent high cost of conventional semiconductor PV systems is overcome by CPV technology through the employment of low‐cost optical elements called concentrators. [ 4 ] However, their widespread application is still limited due to the high temperature of operation, leading to lower electrical efficiency, increased thermal stresses, and decreased module life. [ 5 ] Hence, implementing an effective cooling method is indispensable in CPV systems for enhancing electrical efficiency and avoiding potential damage to the cell.…”

Concentrated photovoltaic (CPV) is a well‐established renewable energy technology. A significant challenge in CPV systems is their low efficiency, majorly due to localized heating yielded from concentration, often requiring the use of cooling systems. The accurate performance analysis and cooling system design for CPV systems require a multiphysics model. Herein, an integrated optical–thermal–electrical model is proposed for the performance evaluation of CPV systems incorporated with different configurations of microchannel heat sinks. The heat sink configuration includes 116 parallel and counter microchannels (Configuration A and B), a single wide microchannel (Configuration C), and single wide minichannel (Configuration D) heat sinks. This study involves 3D Monte‐Carlo ray tracing, finite volume method, and cell‐based electrical modeling. The results indicate that the flux profile over the absorber is highly nonuniform in nature. Furthermore, the CPV system with a Configuration C heat sink achieves a better uniformity in temperature, providing an optimized thermal performance of 64.63%. Moreover, the integrated model considers the impact of PV cell current mismatch that becomes prominent at increasing incidence angles. A maximum deviation of 6.9% in electrical power is obtained while comparing predicted numerical results against experimental results available in literature.

“…Semiconductor materials (e.g., silicon, germanium, and gallium) are used to develop PV cells. Solar cells, such as crystalline Si, amorphous silicon, perovskite crystals, multi-junction (MJ), and thin film, have been developed to be used for various applications [5][6][7]. Among these, MJ cells provide high efficiency.…”

“…By keeping this in view, different studies have been conducted to increase the efficiency of a CPV system by increasing uniform irradiance [17,23,26]. Nonuniform irradiance can affect the cell temperature, fill factor, and mismatch losses [7]. Numerous cooling systems have been developed to improve the performance of the CPV system to maintain the cell temperature [27].…”

Solar energy is a long-established technology, which has zero CO2 emissions, and provides low-cost energy for a given area of land. The concentrator photovoltaic (CPV) has been given preference over the photovoltaic due to its high efficiency. In a CPV system, most of the solar cell area has been replaced with an optical concentrator. Various parabolic trough based CPV systems have been presented where a concentration of <300 is achieved. In the current research, a design is presented to achieve a high concentration of 622×. The design consists of two stages of concentration including parabolic trough as a main concentrator and nonimaging reflective grooves as a secondary concentrator. The trough reflects the incident light towards the secondary reflector where the light is redirected over the solar cell. Design of the two-stage concentrator, ray-tracing simulation, and results are presented. The system achieved an optical efficiency of 79%. The system would also be highly acceptable in solar thermal applications owing to its high concentration.
