“…[7][8][9][10]. Several techniques such as metal organic chemical vapor deposition (MOCVD) [11], thermal evaporation [12], pulse laser deposition (PLD) [13], molecular beam epitaxy (MBE) [14], electrochemical deposition [15], spray pyrolysis [16] and sol-gel [17] are employed to prepare Cd-doped ZnO samples. The sol-gel method has gained much attention due to its low cost, cheap operation and the controllability of the dopant concentration.…”

“…So the maximum attained cell volume variation of 2.33% is achieved before phase separation occurs (x max = 11.2%), whereas it was of 1.8% for polycrystalline Zn (1−x) Cd x O film and respectively 1.7% and 0.9% for c-oriented layer grown on ZnO and c-plane sapphire substrate [22]. In order to compare the effect of Cd incorporation along [hkil] direction, we define the strain in the Zn (1−x) Cd x O layer as:…”

Zn (1−x) Cd x O films have been grown on  1120  (a-plane) and   0112 (r-plane) sapphire substrate by metal organic chemical vapor deposition. A maximum cadmium incorporation of 8.5% and 11.2% has been respectively determined for films deposited on a-and r-plane sapphire. The optical transmission spectra and energy band-gap equation established by Makino et al. were used to estimate the cadmium mole fraction of the solid solutions. Structural, morphological and optical properties of these films were examined using high resolution X-ray diffraction (HRXRD), atomic force microscopy (AFM) and room and low temperature photoluminescence (Pl) as Cd incorporation and employed substrate. X-ray diffraction study revealed that all films had wurtzite phase but solid solution grown on a-plane sapphire are polycrystalline with a preferred orientation along the [0001] direction and a-plane   1120 film are epitaxially grown on r-plane sapphire. AFM image show significant differences between morphologies depending on orientation sapphire substrate but no significant differences on surface roughness have been found. The near band-edge photoluminescence emission shifts gradually to lower energies as Cd is incorporated and reaches 2.916 eV for the highest Cd content (11.2%) at low temperature (20 K). The room temperature hall mobility decreases with the Cd incorporation but it is larger for Zn (1−x) Cd x O grown on r-plane sapphire.

“…Meanwhile, the morphology of the ETL were characterized by atomic force microscopy (AFM), photo-electrochemical impedance spectroscopy (EIS), transmittance, the space charge limited current (SCLC), the charge dissociation probabilities (P(E,T)), which indicate that CZO can obviously improve transparency and morphology, and enhance conductivity. Therefore, the solution-processed of CZO nanoparticles, plays a momentous role in interfacial materials in PSCs or other devices domains requiring HTLs and paves the way for this material to be used in other optoelectronic and photovoltaic applications and beyond [20][21][22][23][24][25][26].…”

In this work, electron transport layers (ETLs)with high charge transfer ability was fabricated by doping ZnO nanoparticles with different concentrations of cadmium. The performance for an inverted polymer solar cell based on PTB7-Th: PC71BM with 5% cadmium doping of zinc oxide nanoparticles (CZO) ETL is better than pure ZnO,which can enhance the short-circuit current (J SC), from 16.30 mA/cm2 to 17.15 mA/cm2, the fill factor (FF) from 64.45% to 69.38%, power conversion efficiency（PCE）from 8.09% to 9.28%. It's consequence of performance stems from curbing interfacial charge recombination and effective charge extraction. Meanwhile, Taking a series of characterization methods, such as atomic force microscopy (AFM), the space charge limited current (SCLC), transmittance, the charge dissociation probabilities (P(E,T)), photo-electrochemical impedance spectroscopy (EIS). The results indicate that the electrical conductivity and transmittance of the films are improved by incorporation of Cd in the ZnO film, restrained surface charge recombination and enhanced the electron-transport capability. Therefore, the ETL of Cd-doped will be an ideal candidate for future optoelectronic devices.
