6 FAQs about [Reasons for solar cell edge jumping]
How does edge recombination affect the efficiency of solar cells?
Because of the influence of edge recombination, the efficiency of silicon solar cells with a small area is often lower than that with a large area (a larger average distance from the edge region). In the IBC solar cells, the edge region of p-n junction is even longer in the interdigital structure of positive and negative electrodes.
Does electrical edge effect affect JSC evaluations for low-light solar cells?
This work emphasized the significant electrical edge effect on JSC evaluations for low-light solar cells and is conducive to understanding the intrinsic mechanism of edge effect, promoting a healthier development of organic photovoltaics.
Why do hard-mask solar cells have a poor fill factor?
Without the interfacial passivation layer, the solar cells fabricated by the hard-mask method suffer severe edge recombination with loss of 3 × 10 −4 A and a quite poor fill factor (FF) of ~66%, suggesting that the edge recombination could be another important issue affecting the FF besides the series resistance.
Why do solar cells have high JSC / Sun?
Some perovskite solar cells and dye-sensitized solar cells (DSSCs) have also reported abnormally high JSC /sun and thus PCE at low light intensity. Such high JSC /sun indicates an external quantum efficiency (EQE) of much higher than 100%, which is impossible for those device systems.
Why does recombination deteriorate in IBC solar cells?
Fourthly, through using simulation method, HTL extending to the gap region may be another reason for the deteriorated edge recombination, leading to an even worse FF. With the guidelines from the above insight, we finally fabricated IBC solar cells with dopant-free heterojunction reaching efficiency to 20.6% and FF to 75.6%.
How does edge recombination affect the fill factor in IBC-dfhj solar cells?
Figuring out the edge recombination is one of the important items affecting the Fill Factor in IBC-DFHJ solar cells. A series of new methods are provided to quantitatively and positionally analyze this edge recombination. By well suppressing the edge recombination, IBC-DFHJ solar cells with a promising PCE of 20.6% was realized.
