Momentum builds for HJT

Cell production: While an inherently conservative business, PV cell production has evolved greatly in terms of cost and efficiency. Heterojunction cell architectures represent more of a step change, when compared to the PERC investment cycle currently underway. In this first of a two part HJT focus, pv magazine speaks to some of the leading technology providers for the high efficiency concept.

There is no doubting the potential of heterojunction (HJT) PV. A relatively mature technology that can deliver 23%-plus cell efficiencies, it is well suited to bifaciality and exhibits an excellent temperature coefficient in the field. On the manufacturing front, there are also advantages. HJT requires fewer process steps than other high-efficiency concepts – four fewer …
