“…So far, the most studied tandem devices containing perovskite layers are perovskite/c-Si, perovskite/CIGS, and perovskite/perovskite. Very recently, laboratory researchers just achieved Perovskite/CdTe [223] and Perovskite/GaAs [219] TSCs, both of which require wide-bandgap perovskite (2.0-2.3 eV for Perovskite/CdTe tandems and 1.8-1.9 eV for perovskite/ GaAs) as the top-cell absorber. Due to the suitable bandgap and absence of photo-induced phase segregation, the pure bromide perovskites such as FAPbBr 3 (2.26 eV), MAPbBr 3 (2.3 eV), and CsPbBr 3 (2.35 eV) are deemed promising candidates for perovskite/CdTe tandem configurations.…”

“…However, a theoretical study predicated that the high optical haze in these materials can hinder incident light from reaching CdTe bottom cells and thus impair the efficiency of the tandem device. [223] In the meantime, the solvent-evaporation-controlled process was demonstrated to contribute to high-efficiency and stable wide-bandgap PSC (1.8-1.9 eV), which enabled GaAs (1.42 eV) to be the rear subcell of perovskite/GaAs tandem architecture. Therefore, the first perovskite/GaAs TSC came out with excellent efficiency of over 25%, [219] which also offered superior bendability as a flexible tandem cell architecture.…”

Tandem solar cells (TSCs) comprising stacked narrow‐bandgap and wide‐bandgap subcells are regarded as the most promising approach to break the Shockley–Queisser limit of single‐junction solar cells. As the game‐changer in the photovoltaic community, organic–inorganic hybrid perovskites became the front‐runner candidate for mating with other efficient photovoltaic technologies in the tandem configuration for higher power conversion efficiency, by virtue of their tunable and complementary bandgaps, excellent photoelectric properties, and solution processability. In this review, a perspective that critically dilates the progress of perovskite material selection and device design for perovskite‐based TSCs, including perovskite/silicon, perovskite/copper indium gallium selenide, perovskite/perovskite, perovskite/CdTe, and perovskite/GaAs are presented. Besides, all‐inorganic perovskite CsPbI3 with high thermal stability is proposed as the top subcell in TSCs due to its suitable bandgap of ≈1.73 eV and rapidly increasing efficiency. To minimize the optical and electrical losses for high‐efficiency TSCs, the optimization of transparent electrodes, recombination layers, and the current‐matching principles are highlighted. Through big data analysis, wide‐bandgap perovskite solar cells with high open‐circuit voltage (Voc) are in dire need in further study. In the end, opportunities and challenges to realize the commercialization of TSCs, including long‐term stability, area upscaling, and mitigation of toxicity, are also envisioned.

“…Compare with the first and second generations of solar cells, the third generation (multi-junction technology) is the introduction of nanotechnology and organic materials into the manufacturing process, but it is still in the research and development (R&D) phase and yet to be commercially applied [ 105 ]. There are currently five types of organic or polymer (OPV); dye-sensitized (DSSC), copper zinc tin sulphide solar cell (CZTS), quantum dot solar cell and perovskite solar cell [ [106] , [107] , [108] ]. Comparison between various types of solar cells is represented in Table 12 .…”

Solar photovoltaic/thermal technology has been widely utilized in building service area as it generates thermal and electrical energy simultaneously. In order to improve the photovoltaic/thermal system performance, nanofluids are employed as the thermal fluid owing to its high thermal conductivity. This paper summarizes the state-of-the-art of the photovoltaic/thermal systems with different loop-pipe configurations (including heat pipe, vacuum tube, roll-bond, heat exchanger, micro-channel, U-tube, triangular tube and heat mat) and nanoparticles (including Copper-oxide, Aluminium-oxide, Silicon carbide, Tribute, Magnesium-oxide, Cerium-oxide, Tungsten-oxide, Titanium-oxide, Zirconia-oxide, Graphene and Carbon). The influences of the critical parameters like nanoparticle optical and thermal properties, volume fraction, mass flux and mass flow rates, on the photovoltaic/thermal system performance are for the optimum energy efficiency. Furthermore, the structure and manufacturing of solar cells, micro-thermometry analysis of solar cells and recycling process of photovoltaic panels are explored. At the end, the standpoints, recommendations and potential future development on the solar photovoltaic/thermal system with various configurations and nanofluids are deliberated to overcome the barriers and challenges for the practical application. This study demonstrates that the advanced photovoltaic/thermal configuration could improve the system energy efficiency approximately 15%–30% in comparison with the conventional type whereas the nanofluid is able to boost the efficiency around 10%–20% compared to that with traditional working fluid.

“…1,2 From initial development to use of carbon as a counter electrode, extensive works have been done in this field, and till date, PSC achieved highest photo-conversion efficiency (PCE) of 25.2%. [3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19] Seeking for interfacial engineering and the grain boundary in the perovskite layer insight can further help to integrate the PSC field towards more stable, reliable and enhanced PCE generating devices. Instead of this massive development, there are issues like upscaling, toxicity, and stability of performance that binds PSCs from commercialization.…”
