Perovskite Solar Cell Efficiency Data from APMS-Modified TiO2 Films

2020 data from Ya-Qiong Wang demonstrates a method to enhance planar heterojunction perovskite solar cell efficiency. The dataset includes measurements of power conversion efficiency (PCE) and fill factor (FF) for cells with and without 3-aminopropyl trimethoxy silane (APMS) hydrolysate-modified electron-transport layers. PCE increased from 13.45% to 15.79% and FF from 62.23% to 68.04%.

Use Cases

• Analyze the correlation between APMS modification and the resulting power conversion efficiency (PCE) values.
• Model the relationship between fill factor (FF) enhancement and interfacial recombination resistance.
• Compare the wettability of γ-butyrolactone (GBL) on modified versus unmodified TiO2 surfaces to predict film quality.
• Benchmark the 15.79% PCE result against other interfacial engineering methods for perovskite solar cells.

Strengths

• Quantified performance improvements with specific PCE (13.45% to 15.79%) and FF (62.23% to 68.04%) metrics.
• Focus on a specific, reproducible interfacial engineering method using APMS hydrolysate.
• Data supports a clear causal claim linking surface modification to efficiency gains.

Limitations

• Dataset scope is limited to a single experimental modification method (APMS).
• Sample size and number of experimental replicates are unknown.
• Data is from a 2020 publication and may not reflect the state-of-the-art in perovskite solar cell efficiency.
