Key Points

Champion performance of 11.2% demonstrates the effectiveness of the studied films, highlighting their potential in energy applications.
Performance metrics were evaluated using advanced techniques like STEM-EDX and SAED to investigate morphology and secondary phases.
Analysis focused on two selenium-based molecular precursor routes used to fabricate Cu(In,Ga)Se2 films for photovoltaic applications.
Findings suggest that differing precursor routes may influence the morphology of thin-film photovoltaics and result in varied performance metrics.

Implication

Comparative analysis reveals 11.2% performance in thin-film photovoltaics, indicating innovative precursor routes show potential benefits.

Abstract

Solution-processed Cu(In,Ga)Se 2 thin-film photovoltaics are prepared via two selenium-based molecular precursor routes. STEM-EDX and SAED are used to analyze film morphology and identify secondary phases. A champion performance of 11.2% is reported.
