Broadly, n-type solar cells are classified into four categories : Front contact with BSF: some examples are passivated emitter rear contact (PERC), passivated emitter rear totally diffused (PERT), passivated emitter rear locally diffused (PERL), emitter wrap-through, and metal wrap-through (MWT).
The champion efficiencies of n/p-type solar cells based on the TOPCon concept have been boosted to 25.8% and 26.1%, respectively, outperforming the conventional passivated emitter and rear contact (PERC) devices, thanks to the efforts of the photovoltaic community worldwide , .
Industrially, this passivated contact scheme is typically coupled with an n-type Czochralski (Cz) wafer. JinkoSolar Holding Co., Ltd. is one of the leading manufacturers that are producing n-type TOPCon solar cells (referred to as ‘HOT’ cells) on a commercial scale.
Generally, in any high-efficiency n-type cell technologies, like in IBC or HIT solar cells, manufacturers are adding one or two production lines in their capacity expansion plans for upcoming years . Thus, n-type technologies will not be extensively accepted until the leap of PERC efficiency growth has been slowed down significantly. 5.4.
It is seen that the solar cells on n/n + substrates show a lower contribution to series resistance compared to mono-crystalline substrates . For concentrator applications, the highest efficiencies were shown by back-contact cells .
JinkoSolar Holding Co., Ltd. is one of the leading manufacturers that are producing n-type TOPCon solar cells (referred to as ‘HOT’ cells) on a commercial scale. In this work, the influence of a post-cell hydrogenation step, using illumination from an LED light source, on the performance and stability of n-type TOPCon solar cells is investigated.
