网页2020年9月1日 · Fill factor (FF) is an important parameter governing the power conversion efficiency (PCE) in non-fullerene organic solar cells (NF–OSCs), which however is less studied than the other two parameters (short-circuit current Jsc and open-circuit voltage Voc). To understand how energy offsets, exciton and charge carrier dynamics impact the FF ...
网页unparalleled high fill factor (FF) of up to 86.59% has also been certified in a separated device. The theoretical FF limit has been predicted to be 89.26%, while the practical FF is far below this limit for a prolonged interval due to the constraints of recombina-tion (i.e., SRH recombination) and series resistance. The ideality factor (m) in the
Fill factor in organic solar cells can exceed the Shockley-Queisser ...
网页2015年6月22日 · Comparing charge generation and recombination in organic donor-acceptor bilayer heterojunction and inorganic p–n junction, we show that such distinctive properties of OSC as interface charge...
Unveiling the mechanism of attaining high fill factor in silicon …
网页The ideality factor (m) in the equivalent circuit of silicon solar cells is consistently ranging from 1 to 2 and rarely falls below 1, resulting in a relatively lower FF than 85%. Here, this work complements a systematic simulation study to demonstrate how to approach the FF limit in design of silicon solar cells
