Enlightening the temperature coefficient of triple mesoscopic CH3NH3PbI3−x Cl x /NiO and double mesoscopic CsFAMAPbI3−x Br x /CuSCN carbon perovskite solar cells

“…As device structure and materials influence the pattern of temperature-related photovoltaic performance, determining the temperature coefficient (T C ) of CPSC devices applying the generalized linear relation is essential for a better understanding of temperature and J-V correlation in real-world conditions, as mentioned in the following equations ( 1 J TC = (∆J/∆T ) 1/J ref (1) V TC = (∆V/∆T ) 1/V ref (2) η TC = (∆η/∆T ) 1/η ref (3) where, J TC represents the T C of current density, ∆J represents the difference between the short-circuit current density at the concerned temperature and reference temperature (reference temperature is 25 [54]. This ion migration is the primary reason behind the chemical instability of halide perovskites and affects their decomposition at temperatures much lower than degradation conditions, but the presence of mixed halide often makes the perovskite more stable due to reduced ion migration [55].…”

“…Innovation and advanced technologies of perovskite solar cells (PSCs) have been universally praised as an economically and environmentally feasible renewable solution in the area of orthodox and conventional solar cell technologies to address global challenges in eco-friendly power generation [1][2][3]. With the progress of materials used as the electron transport layer (ETL), hole transport layer, perovskite layer, and counter electrode, single-junction PSC achieved an outstanding power conversion efficiency (PCE) of >25% [4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20].…”

Effect of novel graphitic carbon/NiO hole transporting electrode on the photovoltaic and optical performance of semi-transparent perovskite solar cells

“…[1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19] These cells mainly consist of electron transport-spacer/ perovskite-hole transport layers, a simple fabrication process exhibiting high power conversion efficiency (PCE) and enhanced stability towards environmental factors. [20][21][22][23][24] Although highly efficient, PSCs sometimes rapidly lose their efficiency due to the hygroscopic and air-sensitive character of the materials used. 25 Therefore, the selection of materials and their fabrication process has a signicant role in the performance.…”

Ground-state structure, orbital ordering and metal-insulator transition in double-perovskite PrBaMn2O6

“…These properties can be further improved and tuned by fabricating double perovskite structures with general chemical formula AA'BB'O 6 (where A/A' are alkaline/rare earth metals, B/B' are transition/nontransition metals). Due to differences in atomic radii of A/A' and/or B/B' ions and possibility of their ordering in alternating perovskite layers, such compounds demonstrate complicated behavior and can serve as a basis for new multifunctional materials [5][6][7][8][9][10][11][12][13][14].…”
