Multifunctional succinate additive for flexible perovskite solar cells with more than 23% power-conversion efficiency

Omnidirectional diffusion of organic amine salts assisted by ordered arrays in porous lead iodide for two-step deposited large-area perovskite solar cells

“…The exponential factor α value of the imprinted PVK-SA device calculated from J sc ∝ I α is 0.995, which is closer to 1 than other samples, indicating the improved charge drift and decreased interfacial charge recombination. 47,48 To obtain more insight into the decay kinetics in fully operating devices, transient photovoltage (TPV) and transient photocurrent (TPC) measurements were carried out. Compared with the control and PVK-SA devices, the imprinted PVK-SA device exhibits the slowest photovoltage decay (Fig.…”

Amorphous F‐doped TiOx Caulked SnO2 Electron Transport Layer for Flexible Perovskite Solar Cells with Efficiency Exceeding 22.5%

“…[ 12,13 ] Hence it will be difficult to achieve their optimum charge transport performance, which becomes an important reason for the efficiency gap between f‐PSCs and rigid PSCs. [ 14–19 ]…”

Go beyond the limit: Rationally designed mixed-dimensional perovskite/semiconductor heterostructures and their applications

“… 14 , 15 , 16 Some molecular agents such as theophylline, caffeine, and theobromine have been systematically investigated for defect passivation; when N–H and C=O are in an optimal configuration in the molecules, the formation of hydrogen bond between N–H and I would assist the primary C=O binding with the antisite Pb defects and maximize the passivation effect. 16 , 17 The passivation strategies are continually advancing to improve the device performance. 18 , 19 , 20 , 21 , 22 , 23 …”
