The facile formation of tin vacancies and oxidation of the divalent tin cation during the thin film fabrication process are among the causes of these problems, because the tin perovskite layer then becomes p-doped, resulting in significant trap-assisted recombination losses in devices. In this ...
High-performance tin perovskite transistors through formate pseudohalide engineering The lack of high-performance p-type semiconducting materials hinders the integration of complementary metal-oxide semiconductors with well-established n-ty...

Growing interest has been shown in the cubic perovskite structure SrTiO3 to produce thermoelectric power [11]. As a result of its high thermal conductivity [12], undoped SrTiO3 has a ZT value of less than 0.5, which can be reduced by adding point defects [13], [14]. It is both ...
Recent years have witnessed rapid development in the field of tin-based perovskite solar cells (TPSCs) due to their environmental friendliness and tremendous potential in the photovoltaic field. Most of the high-performance PSCs are based on lead as the light-absorber material. However, the ...
The performances and stability of Sn-based perovskite solar cells are, however, hindered by the instability of Sn2+ towards oxidation to Sn4+ in ambient conditions, as well as by the abundance of Sn vacancy defects [8], resulting in unwanted doping levels in excess of 1018 cm3 as well as...
we present a four-terminal tandem solar cell architecture consisting of a self-filtered planar architecture perovskite top cell and a silicon heterojunction bottom cell. A transparent ultrathin gold electrode has been used in perov...
Tin-based perovskite has emerged as an excellent luminescent material due to its non-toxicity and narrow bandgap compared to lead-based perovskite. However, its tin ions are easily oxidized by oxygen, which leads to increased vacancy defects and poor crystallinity, presenting a significant challenge ...
