Acetone-assisted precursor engineering enables low-temperature fabrication of CsPbI
Low-temperature fabrication is of vital importance for solar cells in reducing energy consumption and developing diversified device structures. Here, we present an efficient low-temperature fabrication of α-phase CsPbI2Br via introducing a low toxicity and high volatility solvent, acetone, into the...

| 520 | |a Low-temperature fabrication is of vital importance for solar cells in reducing energy consumption and developing diversified device structures. Here, we present an efficient low-temperature fabrication of α-phase CsPbI2Br via introducing a low toxicity and high volatility solvent, acetone, into the precursor to assist the nucleation and growth of perovskite. The addition of acetone significantly improves the wettability of perovskite precursor on compact TiO2 substrate and induces strong interaction between lead iodide and dimethyl sulfoxide solvent. This in turn decreases the crystallization active energy of perovskite, resulting in a fast formation of α-phase CsPbI2Br perovskite at 40 °C. As a result, the acetone-assisted CsPbI2Br device gives a superior power conversion efficiency of 16.03% along with good long-term and operational stability, approaching the highest reported efficiency for CsPbI2Br solar cells. The present study demonstrates that the rational precursor engineering is an effective strategy for low-temperature fabrication of CsPbI2Br solar cells. | ||

Here, we present an efficient low-temperature fabrication of α-phase CsPbI2Br via introducing a low toxicity and high volatility solvent, acetone, into the precursor to assist the nucleation and growth of perovskite. The addition of acetone significantly improves the wettability of perovskite precursor on compact TiO2 substrate and induces strong interaction between lead iodide and dimethyl sulfoxide solvent. This in turn decreases the crystallization active energy of perovskite, resulting in a fast formation of α-phase CsPbI2Br perovskite at 40 °C. As a result, the acetone-assisted CsPbI2Br device gives a superior power conversion efficiency of 16.03% along with good long-term and operational stability, approaching the highest reported efficiency for CsPbI2Br solar cells. The present study demonstrates that the rational precursor engineering is an effective strategy for low-temperature fabrication of CsPbI2Br solar cells.

Acetone-assisted precursor engineering enables low-temperature fabrication of CsPbI |
| abstract |
Low-temperature fabrication is of vital importance for solar cells in reducing energy consumption and developing diversified device structures. Here, we present an efficient low-temperature fabrication of α-phase CsPbI2Br via introducing a low toxicity and high volatility solvent, acetone, into the precursor to assist the nucleation and growth of perovskite. The addition of acetone significantly improves the wettability of perovskite precursor on compact TiO2 substrate and induces strong interaction between lead iodide and dimethyl sulfoxide solvent. This in turn decreases the crystallization active energy of perovskite, resulting in a fast formation of α-phase CsPbI2Br perovskite at 40 °C. As a result, the acetone-assisted CsPbI2Br device gives a superior power conversion efficiency of 16.03% along with good long-term and operational stability, approaching the highest reported efficiency for CsPbI2Br solar cells. The present study demonstrates that the rational precursor engineering is an effective strategy for low-temperature fabrication of CsPbI2Br solar cells. |
