Abstract In this study, the thermal stability of a contact structure featuring hole-selective tungsten oxide (WOx) and aluminum deposited onto p-type crystalline silicon (c-Si/WOx/Al) was investigated using a combination of transmission line measurem

The major factor influencing the behavior of microbes growing in liquids in space is microgravity. We recently measured the transcriptomic response of the Gram-positive bacterium Bacillus subtilis to the microgravity environment inside the Internatio

Doped polycrystalline silicon (poly-Si) passivating contacts featuring a thin tunneling oxide have emerged as one of the most promising carrier selective contacts for crystalline silicon (c-Si) solar cells due to their very low recombination and resi

The contact resistivity ( $\rho _c$ ) of screen-printed contacts is a significant component of series resistance in industrial solar cells. Measuring $\rho _c$ with standard techniques, such as the transmission line method (TLM), requires that the cu

The amorphous silicon layers in silicon heterojunction solar cells absorb light in the short wavelength region of the solar spectrum, lowering the generation current available to the device. Here, we present an alternative to the hole-selective amorp
