High-entropy alloy nanoparticles (HEA-NPs) hold unrestricted promise for various
applications in an unlimited chemical compositional space, as shown in recent years. These …

Carrier collection in silicon heterojunction (SHJ) solar cells is usually achieved by doped
amorphous silicon layers of a few nanometers, deposited at opposite sides of the crystalline …

In silicon heterojunction solar cells made with high-lifetime wafers, resistive losses in the
contacts dominate the total electrical power loss. Moreover, it is widely believed that the hole …

The 730 nm-thick undoped BaSi 2 films capped with 5 nm-thick amorphous Si (a-Si)
intended for solar cell applications were grown on Si (111) by molecular beam epitaxy. The …

The interfacial reaction and bonding mechanism of Si based undoped and Al-doped ZnO
films were investigated experimentally and numerically. Si/ZnO heterojunctions were …

Undoped n-type BaSi 2 films were grown on Si (111) by molecular beam epitaxy, and the
valence band (VB) offset at the interface between the BaSi 2 and its native oxide was …

We investigated the effects of various donors such as Al, Ga, In, and Ti atoms on the
properties of ZnO polycrystalline films. The contents of the dopants in the sintered targets …

Enhancing the probing depth of photoemission studies by using hard X-rays allows the
investigation of buried interfaces of real-world device structures. However, it also requires …

The chemical composition and band alignment at the heterointerface between atomic layer
deposition-grown zinc oxide (ZnO) and hydrogenated amorphous silicon (a-Si: H) is …

Solar energy is the most efficient and cleanest source of energy, as well as a cheap and
eternal source of renewable energy. Improving the energy efficiency of solar panels will …
