Photovoltaic (PV) cells are one of the most common devices to harvest solar radiation and convert it into usable electrical power. However, normal silicone‐based photovoltaic cells work best within the visible light region. Conventional PV panels can use 15–30% of the total energy received, while the remainder is reflected or converted into waste heat. Not only do other wavelengths have lower conversion efficiencies, but they may also increase the cell surface temperature and decrease its overall efficiency. To solve this problem, spectral beam splitting is a potential approach for converting solar energy efficiently. Even though spectral‐splitting systems have high theoretical conversion efficiencies, they have not yet reached the commercial level. The current study describes the advancements in beam‐splitting systems based on thermal PV cells, multijunction cells, nano‐film, conventional, and nanofluids over the last decade. The mechanisms of various splitting system techniques and several hybrid applications are thoroughly discussed in order to provide a comprehensive understanding of solar energy utilization and the considerations influencing system efficiency. Even though the cost increase can be offset by the increased energy conversion efficiency and controlled wavelengths, the system's stability must be addressed for future practical applications.

“…The DMs are made from non-absorbing materials, which have high-optical performance and suitable for a wide range of PV technologies and PV-T hybrid configurations [31][32][33]. Commercial DMs are only available in flat architecture with two angles of incidence (0˚ and 45˚) [34][35][36] and their cost depends on the complexity of production, optical and material specifications [37][38][39]. The DMs have been employed to increase the conversion efficiency of PV systems using single or tandem structures [40][41][42].…”

“…Of the locations considered, Honolulu, HI and Tucson, AZ performed the best over a 10‐year analysis period. Kandilli et al [ 13 ] presented a hybrid lighting‐power generation system that used cold mirrors to split the solar irradiance into its visible and IR spectral components. The visible light was coupled into a fiber optic bundle for indoor lighting, while light in the IR spectral region was used to power a Stirling engine.…”

Hybrid solar lighting (HSL) systems reduce building energy consumption by supplementing conventional indoor lighting with solar light that is channeled into the building using optic cables. Herein, it is demonstrated that HSL systems can be improved by harnessing the nonvisible portion of sunlight to generate electric power. HSL systems are integrated with parabolic‐ and elliptic‐shaped solar spectrum splitters (SSSs) that partition collimated solar radiation into its visible and nonvisible parts. In the proposed SSS, luminescent materials and a bifacial photovoltaic cell capture and convert light energy in the spectral ranges from 280 to 435 nm and 675 to 900 nm into electricity. The visible light is coupled to a waveguide to be used in indoor lighting systems. The proposed HSL system is analyzed for a 0.2 m2 projected area of solar radiation and the results show that a nonvisible‐light‐to‐electricity conversion efficiency of up to ≈13.4% can be achieved for light entering the SSS. The power generated in the system can be used to power the electrical components of the HSL system and indoor lighting during off‐sun hours.
