High-efficiency WSe$_2$ photovoltaics enabled by ultra-clean van der Waals contacts Open
Layered transition metal dichalcogenide semiconductors are interesting for photovoltaics owing to their high solar absorbance and efficient carrier diffusion. Tungsten diselenide (WSe$_2$), in particular, has emerged as a promising solar c…

Cascade hot carriers via broad-band resonant tunneling Open
Extraction of hot carriers (HCs) over the band-edge is a key to harvest solar energy beyond Shockley-Queisser limit1. Graphene is known as a HC-layered material due to phonon bottleneck effect near Dirac point, but limited by low photocarr…

Boosting internal quantum efficiency via ultrafast triplet transfer to 2H-MoTe <sub>2</sub> film Open
Organic systems often allow to create two triplet spin states (triplet excitons) by converting an initially excited singlet spin state (a singlet exciton). An ideally designed organic/inorganic heterostructure could reach the photovoltaic …
