Charge extraction layers play a crucial role in developing the performance of the inverted organic solar cells. Using a transparent metal oxide with appropriate work function to the photoactive layer can significantly decrease interface recombination and enhance charge transport mechanism. Therefore, electron selective films that consist of aluminium-doped titanium dioxide (TiO2:Al) with different concentrations of Al (0.4, 0.8, and 1.2)wt % were prepared using sol-gel technique. The inverted organic solar cells PCPDTBT: PCBM with Al doped TiO2 as electron extraction layer were fabricated. It is well known that Al doping concentration potentially affects the physical characteristics of the TiO2 by controlling the optical, morphological, and structural properties. The effect of Al incorporation on the optical and morphological properties of the prepared films were analysed using UV-Vis spectroscopy, atomic force microscopy (AFM), X-ray diffraction (XRD), and scanning electron microscopy (SEM). The current–voltage (J-V) curves of the PCPDTBT: PCBM organic solar cells show that the TiO2:Al layer with 0.8% Al wt%, has the highest power conversion efficiency which is 3.02%.

“…ZnO is among the most studied ETM layers among the various existing ETM layers. 33,34 The device under consideration behaves like a p-i-n-n 0 configuration (double ETM layered p-i-n configuration), where p-resembles with Al, i resembles with BFO, n resembles the ZnO-uc layer and n 0 resembles with the ITO layer.…”

This work presents a novel paradigm for upconversion‐assisted ferroelectric photovoltaic devices. The system comprises a ferroelectric active layer (BiFeO3), an upconverter layer (Yb; Er‐doped ZnO), a conductive ITO‐coated glass substrate, and a reflective coating (Al) at the rear end of the glass substrate. The photovoltaic efficiency of the single‐layer BFO was found to be 0.71%. With the prescribed device model, the total solar efficiency of BiFeO3 improved significantly and touched solar conversion efficiency of 2.21%. This model's projection widens the future perspectives of device performance in emerging photovoltaic technology, mainly perovskite‐based solar cells.

“…PCBM/C60 was also used in a study resulting in high charge extraction efficiency [12]. ZnO is another promising candidate that is used as the ETL in perovskite solar cells, and recently doped ZnO has shown the power conversion efficiency of 8.98% [13] due to having similar properties to TiO 2 ; however, TiO 2 is extensively studied in PSCs as an ETL and as a front contact in PSC-based tandem solar cells [14]. One of the limitations of the TiO 2 ETL is the presence of trap sites leading to carrier accumulation and low conductivity, as observed in DSSCs applications [15].…”

Ca-doped TiO2 films were synthesized by the modified sol-gel method and employed as the electron transport material of perovskite solar cells (PSCs). Morphological, optoelectronic, thermal, and electrical studies of thin films were investigated through XRD, RAMAN, SEM, AFM, UV- Vis, FTIR, and IV characteristics. Ca doping was detected with the help of structural properties while morphological analysis revealed that thin films based on Ca-doped titania are crack-free, homogenous, and uniformly distributed. Further optoelectronic properties have shown a promising conversion efficiency of 9.79% for 2% Ca-doped titania followed by 1% Ca-doped titania, while 3% have shown the lowest conversion efficiency among these prepared samples. The 2% an optimized doping of Ca has shown an almost two-fold increase in conversion efficiency in comparison to pristine TiO2, along with an increase in current density from 15 mA cm−2 to 19.3 mA⋅cm−2. Improved energy efficiency and higher current density are attributed to faster electron transportation; moreover, the optimized percentage of Ca doping seems to be an effective approach to improve the PSCs’ performance.
