Physically sound parameterization of incomplete ionization in aluminum-doped silicon

AIP Advances, 2016
Incomplete ionization is an important issue when modeling silicon devices featuring aluminum-doped p+ (Al-p+) regions. Aluminum has a rather deep state in the band gap compared to boron or phosphorus, causing strong incomplete ionization.

Photocatalytic Water Splitting on the Lunar Surface: Prospects for In Situ Resource Utilization

Advanced Materials Interfaces, EarlyView.
Water has been found in craters on the moon nearby locations which are illuminated >80% of the time. Photocatalysis uses energy from sunlight to drive chemical reactions such as water splitting to produce oxygen and hydrogen. It is a scalable technology that requires lighter equipment and utilizes resources available on the moon. ABSTRACT The discovery

Low‐Temperature Gold Deposition Improves CdTe Back Contacts

Advanced Materials Interfaces, EarlyView.
Cd(Se,Te) samples are cooled during the evaporation of Au back contacts to thermally quench CdTe degradation. Reduced temperature during Au evaporation boosts PV efficiency, open‐circuit voltage, and fill factor. XPS associates these improvements with less chemical perturbation of the CdTe surface during metallization.
