Open-air stacking solution for photovoltaic brackets

What is stacking in non-fullerene organic solar cells?

Provided by the Springer Nature SharedIt content-sharing initiative In non-fullerene organic solar cells, the long-range structure ordering induced by end-group π–π stacking of fused-ring non-fullerene acceptors is considered as the critical factor in realizing efficient charge transport and high power conversion efficiency.

How efficient is a large-area organic photovoltaic (OPV) module?

New world record efficiency for large-area organic photovoltaic (OPV) modules 14.5% certified power conversion efficiency on total module area, 15.0% on active area Barely any performance loss upon upscaling from 4-mm² cells to >200-cm² modules Industry-relevant processing in ambient air from non-halogenated solvents Context & scale

Can open-air photovoltaic (PV) modules be scalable and fast?

This work demonstrates the first industrially relevant attempt to address both scalable and fast open-air photovoltaic (PV) module manufacturing for the perovskite layer in a single-step conversion and at production speeds >10 m/min, to achieve the highest reported throughput of any solar technology.

Can graded bulk-heterojunction surpass classical BHJ in organic solar cells?

Graded bulk-heterojunction (G-BHJ) with well-defined vertical phase separation has potential to surpass classical BHJ in organic solar cells (OSCs). In this work, an effective G-BHJ strategy via nonhalogenated solvent sequential deposition is demonstrated using nonfullerene acceptor (NFA) OSCs.

Are organic solar cells a promising photovoltaic technology?

Organic solar cells (OSCs) have unique advantages of light weight, low-cost solution processing, and capability to be fabricated into flexible and semitransparent devices, which are widely recognized as a promising photovoltaic technology.

Can intermixed solid-state packing improve photovoltaic performance?

The intermixed solid-state packing motif in active layers could enable organic solar cells with superior efficiency and reduced non-radiative recombination loss compared with devices based on molecules with the classic end-group π–π stacking mode. Our observations open a new avenue in material design that endows better photovoltaic performance.
