Interfacial Modulation for High‐Efficiency Large‐Area Organic Photovoltaics and Perovskite‐Organic Tandem Solar Modules

Advanced Functional Materials, EarlyView.
Self‐assembled monolayers (SAMs) are promising hole‐transporting materials for organic photovoltaics (OPVs), but suffer from self‐aggregation and poor large‐area uniformity. We find that interfacial modification using nicotinic hydrazide can eliminate the residual SAM aggregates by forming energetically favorable complexes, yielding uniform SAM.

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.
