Nonfullerene acceptors tend to decompose in the presence of ZnO due photocatalytic activity, and SnO<sub>2</sub>is an alternative for higher efficiency better stability.
Achieving high power conversion efficiency and good mechanical robustness is still challenging for the ultraflexible organic solar cells. Interlayers simultaneously having chemical compatibility with active layer are highly desirable. In this work, we present an interlayer of Zn2+-chelated polyethylenimine (denoted as PEI-Zn), which can endure a maximum bending strain over twice that ZnO chemically compatible recently emerging efficient nonfullerene layers. On 1.3 μm polyethylene naphthalate...
Abstract Nonfullerene (NF) organic solar cells (OSCs) have been attracting significant attention in the past several years. It is still challenging to achieve high‐performance flexible NF OSCs. acceptors are chemically reactive and tend react with low‐temperature‐processed low‐work‐function (low‐WF) interfacial layers, such as polyethylenimine ethoxylated (PEIE), which leads “S” shape current‐density characteristics of cells. In this work, chemical interaction between active layer polymer...
All-solution-processed organic solar cells (from the bottom substrate to top electrode) are highly desirable for low-cost and ubiquitous applications.

We achieve comparable performance and improved stability compared reference evaporated electrodes by using...
Non-fullerene acceptor ITIC can react with PEI (or PEIE), which destroys the original intramolecular charge transfer in ITIC.
Vertical phase distribution plays an important role in the quasi-two-dimensional perovskite solar cells. So far, driving force and how to tailor vertical of layer numbers have been not discussed. In this work, we report that films deposited on a hole-transporting is different from glass substrate. The could be explained by sedimentation equilibrium because colloidal feature precursors. Acid addition will change precursors colloid solution therefore changes distribution. A self-assembly used...
