“…The tin-based perovskite material has emerged as a promising candidate to replace lead perovskite solar cells, currently presenting a maximum power conversion efficiency of 14.8%. [5][6][7][8][9][10][11] The tin-based perovskite materials do not offer long term stable operation because Sn 2+ ions rapidly oxidizes to a more stable Sn 4+ in the presence of air and moisture. Recently significant progress has been made in restricting the oxidation of Sn 2+ ions with the development of encapsulation and fabrication methods.…”

The choice of appropriate materials is of paramount importance in realizing a high efficiency perovskite solar cell. Lead free eco-friendly perovskite solar cell architecture is theoretically investigated using solar cell capacitance simulator (SCAPS) for device performance. Preliminary investigations on Cs 2 SnI 6 solar cell architectures have indicated that the presence of hole transport layer is crucial in achieving an open-circuit voltage greater than 0.6 V. The presence of a valence band offset between the Cs 2 SnI 6 absorber and hole transport layer has a significant detrimental impact on the short-circuit current density and fill factor of the cell. A novel device architecture employing TiO 2 as an electron transport material and Cu 2 O as a hole transport material is proposed to overcome the limitations associated with the current designs. Theoretical investigations are carried out employing 1D SCAPS simulation program in order to optimize the structure by varying the perovskite thickness, bandgap, and defect concentration. The proposed solar cell after optimization has a practically realizable power conversion efficiency of 17.77%.

“…Moreover, the organic MA and FA cations in Sn-HPs decompose at 200 °C, showing lower thermal stability in comparison to Cs-based Sn-HPs, that with a melting point as high as 451 °C due to the strong covalent/ionic interaction between Cs + and halogen anions, facilitates the formation of the [SnI 6 ] 4− octahedron. Thus, the free energy is reduced along with the enhancement of the thermodynamic stability of the crystal structure 103,104 .…”

Due to their outstanding optoelectronic properties, lead-based halide perovskite materials have been applied as efficient photoactive materials in solution-processed solar cells. Current record efficiencies offer the promise to surpass those of silicon solar cells. However, uncertainty about the potential toxicity of lead-based halide perovskite materials and their facile dissolution in water requires a search for new alternative perovskite-like materials. Thanks to the foresight of scientists and their experience in lead-based halide perovskite preparation, remarkable results have been obtained in a short period of time using lead-free perovskite compositions. However, the lower solar-to-energy conversion efficiency and long-term stability issues are serious drawbacks that hinder the potential progression of these materials. Here, we review and analyse strategies in the literature and the most promising solutions to identify the factors that limit the power conversion efficiency and long-term stability of lead-free tin-based perovskite solar cells. In the light of the current state-of-the-art, we offer perspectives for further developing these promising materials.
