Improved photovoltaic properties of dye sensitized solar cell by irradiations of Ni ²⁺ ions on Ag‐doped TiO ₂ photoanode

Abstract

Using the dip-coating technique we report here the synthesis of pure and 1% Ag-doped TiO 2 thin films. The 1% Ag-doped TiO 2 films are then irradiated with Ni ions at different (2 × 10 14 , 4 × 10 14 , and 6 × 10 14 ions/cm 2 ) fluences. Structural analysis carried out using the X-ray diffraction technique revealed the evolution of anatase phase in addition to rutile traces. The corresponding lattice parameters (a and c) first increases with doping and irradiation of Ni ions up to 4 × 10 14 ions/cm 2 which then decreases on a further increase of fluence.UV-visible spectroscopy shows a decreasing behavior of band gap energy (E g ) with doping. The minimum value of E g is 3.1 eV which is obtained when 4 × 10 14 ions/cm 2 of Ni ions are implanted on 1% Ag-TiO 2 film. These films are tested as a photoanode for dye sensitized solar cells (DSSCs) and calculate their efficiency. The cell formed by Ni ions implanted on 1% Ag-TiO 2 as photoanode with fluence of 4 × 10 14 ions/cm 2 showed the highest current density of 6.13 mA/cm 2 with maximum efficiency of 3.01%.

The Effect of 600 keV Ag Ion Irradiation on the Structural, Optical, and Photovoltaic Properties of MAPbBr3 Films for Perovksite Solar Cell Applications

“…These curves were used to calculate the photovoltaic parameters of the pure and Ag-irradiated MAPbBr 3 -based solar cells such as the short circuit current density ( J sc ), conversion efficiency ( η ), open-circuit voltage ( V oc ), and fill factor ( FF ), as summarized in Table 3 . To determine the power conversion efficiency, the Equation (12) was used [ 65 ].…”

“…TiO 2 is a transition metal-oxide semiconductor, [102,103] predominantly used in photo-catalytic, [104][105][106][107][108] photo-electrochemical water splitting, [109][110][111][112] and photo-voltaic [12,[113][114][115] applications. A good description of TiO 2 can be found in the reviews.…”

Impact of Cr doping on the structural and optoelectronic properties of a CsPbIBr2 perovskite solar cell

“…The coated substrate was subsequently placed in an oven for a specific period and at a specific temperature to expedite the evaporation of the solvent and the crystallization of the CsPbIBr 2 coating. 11…”

“…It has been demonstrated that doping, a commonly used process in semiconductor technology, offers a promising way to enhance the structural and optoelectronic characteristics of perovskite materials. 11 Doping has the capability to augment stability, optimize the mobility of charge carriers, and alter the band structure, consequently heightening the effectiveness of solar cells. Tan et al replaced Cs positions in order to improve crystallinity and structure, in conjunction with the less massive monovalent alkali metal ion Li + .…”
