Michele De Bastiani and colleagues address the main challenges of bifacial perovskite/silicon tandem solar cells in their last perspective published in Joule. Bifacial tandems are a great innovation to combine stability and performance at once, bringing the perovskite technology one step closer to its commercialization.
This work, which took place in ACS Energy Letters, reports the photoactivated p-doping of PTAA (widely used hole transport layer) to enhance hole extraction for (textured) perovskite/silicon tandem solar cells, making the device performance less sensitive to the variation of hole transport layer thickness.
Arsalan Razzaq and colleagues from KPV-Lab recently published their perspective in Joule, discussing the techno-economic barriers for the industrial adoption of silicon heterojunction technology. This work highlights critical areas that need to be addressed for enabling terawatt-scale silicon heterojunction deployment.
