研究目的
Investigating the angle effect on the synthesis of BiOI films via modified SILAR and its impact on photovoltaic performance.
研究成果
The angle variation in BiOI synthesis via modified SILAR affects film thickness, morphology, and photovoltaic performance. Vertical synthesis (90°) yields better Jsc and Voc, suggesting that angle control is crucial for optimizing BiOI solar cells.
研究不足
The study focuses on the angle effect on BiOI film synthesis and its photovoltaic performance, but does not explore the full range of potential applications or the scalability of the synthesis method.
