Development of High Efficiency SHJ/Poly-Si Passivating Contact Hybrid Solar Cells

To improve the conversion efficiency of c-Si solar cells, it is crucial to quench the recombination losses at c-Si/metal interface. Such recombination losses are able to be reduced by using carrier-selective passivating contacts by means of hydrogenated amorphous silicon (a-Si:H) and poly-crystalline silicon (poly-Si)/tunneling silicon oxide ...

Deposition of Hydrogen-Doped Indium Oxide Thin Films Using Atmospheric-Pressure Plasma-Enhanced Spatial Atomic Layer Deposition

Transparent conductive oxides (TCOs) are wide bandgap semiconductors characterized by high conductivity and high transparency in the visible and near infrared spectrum of light. TCOs find applications in displays, thin film transistors, solar cells, etc., due to these distinctive properties. Hydrogen-doped indium oxide (IO:H), a TCO first...

Large Tunability of Strain in WO₃ Single-Crystal Microresonators Controlled by Exposure to H₂ Gas

Strain engineering is one of the most effective approaches to manipulate the physical state of materials, control their electronic properties, and enable crucial functionalities. Because of their rich phase diagrams arising from competing ground states, quantum materials are an ideal playground for on-demand material control and can be used...
