Thermoradiative Diodes Using Black Phosphorus van der Waals Materials

Advanced Energy Materials, EarlyView.
We demonstrate thermoradiative diodes based on black phosphorus (bP${\rm bP}$)/molybdenum disulfide (MoS2$MoS_2$) van der Waals heterojunctions which generate power by exchanging photons with a colder environment. The bandgap of black phosphorus is well positioned to exchange photons with outer space through the mid‐wave atmospheric window.

Nickel‐Free Perovskite Solar Cells Enabled by Self‐Assembled Monolayers: A Pathway to Efficient and Recyclable Devices

Advanced Energy Materials, EarlyView.
Replacing toxic NiOx with phenyl‐substituted phosphonic‐acid carbazole monolayers (Ph‐5PACz) yields inverted perovskite solar cells that are efficient and recyclable. The nickel‐free interface reaches 25.3% efficiency and enables closed‐loop ITO recovery with near‐98% performance retention, while life‐cycle and techno‐economic analyses confirm lower ...

Characterizing Fill Factor Limitations in Perovskite‐Silicon Tandem Solar Cells

Advanced Energy Materials, EarlyView.
The fill factor of monolithic perovskite‐Si tandem solar cells is limited by the photoshunt behavior of the perovskite top cells, which is the result of the competition between slow charge extraction through the transport layers and recombination in the absorber.
