Non-preheating fabricated semitransparent quasi-2D perovskite solar cells

Abstract

Although the hot-casting (HC) method can obtain efficient quasi-2D perovskite solar cells, this method cannot effectively control the uniformity of the thin film, and the high preheating substrate temperature will...

Alkyl radicals from diacyl peroxides: metal-/base-/additive-free photocatalytic alkylation of N-heteroaromatics

“…13 Moreover, Pan and Yu's group disclosed a Ru-photocatalyzed decarboxylative alkylation of enamides with alkyl diacyl peroxides under visible-light irradiation (Scheme 1e). 14 It should be noted that transition metal photocatalysts, additives, and conventional organic solvents are still unavoidable in the previously reported photocatalytic systems.…”

Charge transfer doping of graphene oxide with nickel oxide nanoparticles for stable and efficient carbon-based, all-inorganic CsPbBr3 perovskite solar cells

“…3b. According to V oc = nkT ln (I)/q + constant (where n is the ideality factor, T is the absolute temperature, k is the Boltzmann constant and q is the elementary charge 32,33 ), the decreased ideality factors demonstrate that NiO x decorated GO effectively suppresses the trap-assisted Shockley-Read-Hall (SRH) recombination. EIS measurements were carried out to further explore the reactions undergone by photoexcited electrons at the interfaces, as shown in Fig.…”

Br Addition Combined with Non-Preheating Method to Prepare Semitransparent Quasi-2D Perovskite Solar Cells with High Average Visible Light Transmittance

“…Since then, the HC process has been commonly used in high-efficiency 2D-PSCs; however, the hot-casting method can improve the cell efficiency, while it significantly increases the thickness of the perovskite film, which will lead to a significant decrease in AVT, resulting in a decrease in LUE (LUE = PCE × AVT, LUE is an important indicator used for the measure of performance about ST-PSCs). Therefore, we chose the nonpreheating method to prepare perovskite films with smaller thicknesses and higher AVT (a specific study of the advantages and disadvantages of HC and NP was published in the Luo group’s article).…”
