Confinement of MACl guest in 2D ZIF-8 triggers interface and bulk passivation for efficient and UV-stable perovskite solar cells

Abstract

Rational passivation of the defects at the buried interface plays a significant role in reducing energy loss and improving the photovoltaic performance of perovskite solar cells (PSCs). Herein, we applied...

Fluorocarbon Surfactant‐Assisted Large‐Area Uniform and Water‐Resistant Perovskite Films for Efficient Photovoltaics

“…It is well-known that the extraction and transfer of interfacial charges is highly dependent on the built-in potential (V bi ) of the PSC. [46,47] V bi can be obtained by linearly fitting the Mott-Schottky curves, as shown in Figure 5b. After the introduction of FS additive, the V bi of the device increases from 0.91 to 1.00 V. The enhanced V bi implies a higher ability to separate the photogenerated carriers, leading to a higher V OC .…”

Applications of multifunctional metal–organic frameworks in perovskite photovoltaics: roles, advantages and prospects

“…4b), thus enabling durable perovskite photovoltaics to be realized. 16 Subsequently, Dou and co-workers employed Eu-MOF as an interface modifier that was sandwiched between the SnO 2 layer and the perovskite layer to improve device performance (Fig. 4c).…”

Crystalline porous materials in perovskite solar cells: a mutually beneficial marriage

“…Meanwhile, due to the UV-resistant property of ZIF-8 and the double passivation of the host and guest groups, the UV stability and humidity stability of the device are more prominent than that of the control device. 77 Consequently, the CPMs confined ammonium salts presented in these works provide innovative perspectives and effective methods for buried interface passivation and even other aspects of device defect management.…”
