| Abstract Scope |
This study examines ZnO nanorod growth using a hydrothermal process to be used as an electron transport layer (ETL) for the emerging low-cost and high-performance perovskite solar cells. The perovskite absorber coated around the nanorods enhances charge collection by shortening their path length. For the hydrothermal synthesis, glass substrates sputtered with Al-doped or undoped ZnO seed layers were used. By changing the precursor concentrations and proportionalities with the complexing agents, the temperature and time of the synthesis process, we were able to attain various nanorod morphologies and thicknesses. To avoid contamination on the surfaces, nanorods were grown upside down. To improve conductivity of the nanorods, Al-precursors were added to the Zn-precursor solution. Both lead and tin-based perovskite materials were coated on the fabricated nanorods. While the lead-based material degraded, the tin-perovskite did not. Further testing on the compatibility with these perovskite materials must be conducted to achieve functional solar cells. |
