How efficient are silicon heterojunction solar cells?

Silicon heterojunction (SHJ) solar cells have achieved a record efficiency of 26.81% in a front/back-contacted (FBC) configuration. Moreover, thanks to their advantageous high VOC and good infrared response, SHJ solar cells can be further combined with wide bandgap perovskite cells forming tandem devices to enable efficiencies well above 33%.

What is heterojunction technology?

Heterojunction technology is currently a hot topic actively discussed in the silicon PV community. Hevel recently became one of the first companies to adopt its old micromorph module line for manufacturing high-efficiency silicon heterojunction (SHJ) solar cells and modules.

Are heterojunction cell architectures a step change?

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.

Can silicon heterojunction solar cells be used for ultra-high efficiency perovskite/c-Si and III-V/?

The application of silicon heterojunction solar cells for ultra-high efficiency perovskite/c-Si and III-V/c-Si tandem devices is also reviewed. In the last, the perspective, challenge and potential solutions of silicon heterojunction solar cells, as well as the tandem solar cells are discussed. 1. Introduction

What is silicon heterojunction (SHJ) technology?

This perspective focuses on the latter PC technology, more commonly known as silicon heterojunction (SHJ) technology, which achieved the highest power conversion efficiency to date for a single-junction c-Si solar cell. Moreover, the SHJ technology has been utilized in realizing world record perovskite/c-Si tandem solar cells.
