Which polymer modification boosts open-circuit voltage for perovskite solar cells?

Xiaomei Lian, Jiehuan Chen, Shiqi Shan, Gang Wu, Hongzheng Chen. Polymer Modification on the NiOx Hole Transport Layer Boosts Open-Circuit Voltage to 1.19 V for Perovskite Solar Cells.

Do Y6 acceptors improve photovoltaic performance?

The emergence of Y6-type nonfullerene acceptors has greatly enhanced the power conversion efficiency (PCE) of organic solar cells (OSCs). However, which structural feature gifting the excellent photovoltaic performance is still under debate. In this work, two Y6-like acceptors BDOTP-1 and BDOTP-2 were designed.

Are thiophene cores suitable for perovskite solar cells?

The exploration of alternative low-cost molecular hole-transporting materials (HTMs) for both highly efficient and stable perovskite solar cells (PSCs) is a relatively new research area. Two novel HTMs using the thiophene core were designed and synthesized (Z25 and Z26).

What is a fixed adjustable photovoltaic support structure?

In order to respond to the national goal of “carbon neutralization” and make more rational and effective use of photovoltaic resources, combined with the actual photovoltaic substation project, a fixed adjustable photovoltaic support structure design is designed.

Is alkyl chain branching point a useful strategy for optoelectronic devices?

Manipulation of the alkyl chain branching point has emerged as an effective strategy to enhance the performance of conjugated polymers in optoelectronic devices.
