A version of this article originally appeared in the 2022 edition of RETC’s PV Module Index Report. By Daniel Chang, VP of Business Development, RETC In 2022, the Renewable Energy Test Center (RETC) is closely monitoring a technology trend gaining market traction and acceptance: the rise of next-generation n-type PV cells with passivating contacts.
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.
The total market coverage of n-type solar cells in 2016 was 92% by c-Si and 8% by thin-films [47, 48], as shown in figure 1 (a). Of the 92% of c-Si solar cell coverage, mc-Si covered 68% of the total solar cell market and 32% was covered by mono-crystalline Si, as shown in figure 1 (b).
Solar manufacturers have long recognized the potential efficiency benefits of n-type PV cells. For example, Sanyo began developing n-type heterojunction technology (HJT) PV cells in the 1980s. In addition, SunPower has built its interdigitated back contact (IBC) PV cells upon a base of high-purity n-type silicon.
At present, a cell with an area of 79 cm 2 has already demonstrated a PCE of 26.7%, and a cell with an area of 180 cm 2 (which would be a truly amazing size for other PV technologies) reached a PCE of 26.6%. These cell results lead us to anticipate that the module efficiency will also increase in the near future.
