Dimensional diversity (0D, 1D, 2D, and 3D) in perovskite solar cells: exploring the potential of mixed-dimensional integrations

Abstract

Perovskite solar cells (PSCs) are promising photovoltaic (PV) technologies due to their high-power conversion efficiency (PCE) and low fabrication cost. This review article delves into the changing PSC landscape by...

Bandgap Engineering and Enhancing Optoelectronic Performance of a Lead-Free Double Perovskite Cs2AgBiBr6 Solar Cell via Al Doping

“…As a result, for the Al-doped material, the Fermi level moves upward into the CB, giving rise to the formation of an n-type semiconductor and making optical transitions more accessible. This shift in the Fermi level and the easier optical transition account for the increase in the V oc value. − The FF of a solar cell is calculated by dividing the maximum power output ( P max ) by V oc × J sc , : FF = P max J sc × V oc where P max = ( J max × V max ). The FF value of pure was 0.67, but after doping, its value increased to 0.71.…”

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

“…The following equation was used to determine the absorption coefficient ( α ): 42,43 The energy band gaps of the pure film and 4% and 6% Cr–CsPbIBr 2 films were calculated to be 2.20, 2.03 and 2.33 eV, respectively. The variations in energy band gaps among the pure film and 4%, and 6% Cr–CsPbIBr 2 samples can be attributed to the impact of chromium doping on the material's electronic structure.…”

The structural, optical and photovoltaic properties of Zn-doped MAPbI2Br perovskite solar cells

“…For example, if Zn doping induces compressive strain, it may result in an increase in the lattice constant. 56 The inclusion of Zn may cause flaws, vacancies, or disorder in the crystal lattice at a concentration of 4% Zn doping. The lattice constant may be impacted by these structural modifications.…”
