English Abstract

The sol-gel ZnO nanoparticles were found to form a relatively compact film without sintering steps throw low temperature process (<1200C) to perform perovskite solar cells using a spin coating technique.

The perovskite layer was sandwiched between zinc oxide (ZnO) nanoparticles thin film as a selective electron transport layer (ETL) and organic hole selective poly (3,4-ethylenedioxythiophene): poly (styrene sulfonate) PEDOT:PSS layer.

A methylammoniom lead iodide (CH3NH3) PbI3 active layer was deposited on the ZnO nanoparticles modified ITO substrate.

X-Ray Diffraction (XRD), field emission scanning electron microscope (FESEM) were employed to characteristic structure and morphology of the samples.

Photoluminescence (PL) spectroscopy used for optical band gap energy for ZnO nanoparticles, methyl ammonium lead iodide (CH3NH3)PbI3 perovskite were calculated to be 3.27, 1.62 eV respectively.

The crystalline ZnO nanoparticles 15 nm in diameter were determined by transmission electron microscope (TEM).

The whole device could be fabricated under mild conditions with relatively low temperature and solution process.

Devices based on modified (ETL) could achieve high power conversion efficiency (PCE) 7.41 on rigid and 4.65 on flexible substrates with improved device stability.

These results imply that interface engineering provides a promising approach to simplify device configuration and reduce the fabrication cost for perovskite solar cells.
