Special Issue Information
Dear Colleagues,
Perovskite solar cells (PSCs) based on various materials, such as all-inorganic and organic–inorganic perovskite-based light-absorbing materials, have shown great potential for high-efficiency photovoltaic applications. These perovskite materials have been widely used to prepare single-junction and multi-junction perovskite and perovskite-based tandem solar cells. The performance of these devices depends on several factors, such as light absorption, the bandgap of the materials, charge carrier dynamics and transport, and the interfacial charge transfer phenomenon. Understanding these factors is essential for improving the stability and commercial viability of this astonishing technology. Moreover, developing new materials, mechanisms of research, and device architecture with improved efficiency and stability of perovskite and perovskite-based tandem solar cells is also highly desirable.
This Special Issue of Energies invites original research and review articles on the latest developments in solar cells based on perovskite materials. We are particularly interested in papers that explore the development of new materials, device architectures, and improved photovoltaic and optoelectronic characteristics of perovskite and perovskite-based tandem solar cells. This Special Issue aims to provide a comprehensive overview of the current state of the art and future perspectives in this field. We welcome your submissions to this Special Issue.

Abstract: The graded layer technology plays a pivotal role in achieving high solar cell efficiency work as a tandem device. This study aims to propose a novel graded physical parameters configuration for a mixed Pb/Sn halide perovskite implemented within a device structure comprising FTO/SnO_2/perovskite/Spiro-OMeTAD/Au. An exceptional power conversion efficiency (PCE) of 36.32% was attained, signifying remarkable performance. The SCAPS-1D program was utilized for performance parameter calculations, including PCE, current density (Jsc), open-circuit voltage (Voc), and form factor (FF). Validation of the simulation involved comparing current density characteristics (J-V), external quantum efficiency (EQE), and performance parameter values with experimental results. Optimization of PCE was achieved by investigating the effects of various inorganic HTL (CuSCN,〖Cu〗_2 O, and CuI), the thickness (d), defect density (N_t), graded doping concentration (N_A (A), N_A (B), N_D (A) and N_D (B)) in both sides left (A) and right (B) of the absorber layer, series (R_s) and shunt (R_sh) resistance, work function of front 〖(W〗_fF) and back 〖(W〗_fB) contact, finely the graded bandgap (E_(g ) (A), E_(g ) (B)) in both sides A and B of the absorber layer. The optimum physical parameters found are d=1µm,N_t=10^12 cm^(-3), N_D (A)=10^19 cm^(-3), N_D (B)=10^19 cm^(-3), N_A (A)=10^9 cm^(-3),N_A (B)=〖3.5*10〗^17 cm^(-3), R_s=0 Ω cm^2, R_sh=10^6-10^10 Ω cm^2, W_fF=4.25eV,W_fB=5eV-7eV, E_g (A)=1.65eV and E_g (B)=1.4eV, yielding an outstanding PCE of 36.32% with V_oc=1.466V,J_sc=27.21mA/cm^2 and FF=91.08%.

Abstract: Tin Oxide (SnO2) with low-temperature processability has been observed to be an appropriate material for the “electron transport layer” (ETL) of the planar structure of perovskite solar cells (PSCs). The ETL is necessary for the extraction of electrons and charge separation from the perovskite active layer. Herein, we present a study of the annealing temperature effect of SnO2 as an ETL on the efficiency of devices for low-cost manufacturing. The annealing temperature of SnO2 considerably affects the morphology, crystallinity, grain size, and surface topography of the SnO2 layer, eventually affecting the properties of the perovskite film. In this study, the annealing temperature of SnO2 deposited using spin coating was changed from 90 °C to 150 °C. The SnO2 annealed at 120 C resulted in reduced surface defects, improved electron extraction, and a significant enlargement in the grains size of the perovskite active layers, resulting in improved efficiency of PSCs. The best device yielded an average efficiency of 15% using 0.36 cm2 active area, while devices treated at 90 °C and 150 °C achieved an average efficiency of 12%. The PSCs fabricated with low temperatures provide an effective technique for low-cost manufacturing on flexible substrates.
