Increase in photovoltaic performance of solar cells by optimization of temperature and time of TiO2 surface modification |
| 초록 |
We have modified TiO2 surfaces using aqueous sodium hydroxide (NaOH) solution at different solution temperatures and soaking time via a simple dip coating process, and the resulting electrodes (SH-TiO2/FTO) were used as a electron transporting layers of solar cells. The device with bare-TiO2/FTO showed the performance with Voc=0.59 V, Jsc=18.84 mA/cm2 and FF=61.28%, which leads to a power conversion efficiency (PCE) of 6.80%, whereas, for the device with SH(40/10)-TiO2/FTO prepared by surface treatment at 40℃ for 10 min, the PCE was increased to 7.60% (Voc = 0.72 V, Jsc = 17.52 mA/cm2 and FF = 61.81%) due to an increase in Voc by more than 22%. |
