What is a cathode interlayer (CIL) & anode interlayer (AIL)?

To overcome these problems, it is currently a canonical paradigm to insert a proper cathode interlayer (CIL) and anode interlayer (AIL) [18 –20]. The basic functions of CILs/AILs can be summarized as follows: (i) modifying the WFs of metal electrodes by forming interfacial dipoles to ef ciently sweep out the charge

How can cathode interfacial materials improve photovoltaic performance?

This results in an increased energy barrier between the electrode and the active layer. To mitigate the interfacial energy barrier, the introduction of cathode interfacial materials (CIMs) between the photoactive layer and the cathode can be employed, effectively optimizing the photovoltaic performance of OSCs [17, 18].

What are cathode interfacial materials?

Cathode interfacial materials (CIMs) are particularly crucial for enhancing the photovoltaic performance of OSCs. They facilitate the formation of efficient ohmic contacts between the active layer and the cathode, lower the work function (WF) of the cathode, and optimize charge transport characteristics within the devices.

What are organic solar cells?

Organic solar cells (OSCs) have garnered significant attention in recent years due to their inherent advantages of simple device architecture, lightweight nature, solution processability, and capability to fabricate semitransparent and flexible devices. The power conversion efficiency of state-of-the-art OSCs has now surpassed 20 %.

Can spent cathode materials be repaired?

This study sheds new light on the reparation of spent cathode materials and designing high-performance compositions to mitigate structural degradation. Rapid capacity decay and voltage drop hinder lithium- and manganese-rich cathode material (LMRO) development.

Are organic solar cells based on non-fullerene acceptors the future of photovoltaic technology?

Organic solar cells (OSCs) based on non-fullerene acceptors have recently achieved high power conversion efficiencies over 19%, thus rapidly advancing third-generation photovoltaic technologies.
