研究目的
To enhance the performance of planar perovskite solar cells (PSCs) by devising an antireflective cascaded SnO2/TiO2-Cl electron transport layer (ETL) to reduce primary optical reflection and achieve a record-high short-circuit current density.
研究成果
The antireflective cascaded ETL strategy effectively increases the photocurrent density of planar PSCs without compromising electrical performance, achieving a record-high Jsc of 26.1 mA cm-2 and a PCE of 22.9%. This approach offers a simple and versatile method to improve the efficiency of planar perovskite solar cells.
研究不足
The study does not explicitly mention limitations, but potential areas for optimization could include further reducing the thickness of ETL layers without compromising performance and exploring the scalability of the fabrication process.
