Challenges in tin perovskite solar cells

Abstract

Perovskite solar cells are the rising star of third-generation photovoltaic technology. With a power conversion efficiency of 25.5%, the record efficiency is close to the theoretical maximum efficiency for a...

“…), and halogen anion respectively [3]. Organic‐inorganic perovskites have shown remarkable progress over a short period in solar cells technology with a maximum conversion efficiency of 25.5 % [4].…”

Nucleation and crystallization manipulations of tin halide perovskites for highly efficient solar cells

“…72 Remarkably, from the previous research, Sn 2+ on the surface is more prone to oxidize than that in the bulk. 102 Bulk Sn 4+ tends to release two holes to the valence band and be reduced to Sn 2+ . 103 Therefore, it is meaningful to make more efforts on surface antioxidation, including interfacial modification reductants, a surface reducing atmosphere, or 2D/3D perovskites.…”

The effect of Sr substitution on the structural and physical properties of manganite perovskites Ca1−xSrxMnO3−δ (0 ≤ x ≤ 1)

“…gas sensors, 1 solid oxide fuel cells, [2][3][4][5][6] batteries, [7][8][9][10] photocatalysis, 11-13 catalysis [14][15][16] and photovoltaics. 17 Among these perovskite materials, CaMnO 3 (CMO) has great potential to be used as an anode material for Li-ion batteries owing to its unique features of cost effectiveness, good structural variability and high specific capacity (225.4 mA h g À1 ) after 90 cycles at standard temperature. 9 CMO can also be used as a cathode material for rechargeable lithium-oxygen batteries due to its good cyclability and high performance.…”
