Dual-function of CdCl2 treated SnO2 in Sb2Se3 solar cells

Numerical Simulation and Performance Evaluation of Highly Efficient Sb2Se3 Solar Cell with Tin Sulfide as Hole Transport Layer

“…In the last few years, antimony selenide (Sb 2 Se 3 ) semiconductor has received considerable attention as an attractive absorber material in the thin‐film heterojunction photovoltaic device due to its high absorption coefficient (>10 5 cm −1 ), favorable energy bandgap (1–1.2 eV), reasonable carrier mobility, low toxicity, earth‐abundant constituents, inexpensive, low temperature fabrication process, and excellent stability. [ 20–30 ] In the previous works, several experimental [ 20–23,27,31–40 ] and theoretical [ 41–47 ] studies on improving the performances of the Sb 2 Se 3 ‐based solar cells have been reported. There have been numerous experimental Sb 2 Se 3 ‐based heterojunction solar structures, including TiO 2 /Sb 2 Se 3 , [ 18 ] TiO 2 /Sb 2 Se 3 /CuSCN, [ 31 ] CdS/Sb 2 Se 3 , [ 23,32,33,35,36,38–40 ] CdS/Sb 2 Se 3 /PbS, [ 34 ] and CdS/Sb 2 Se 3 /CuSCN, [ 37 ] described to achieve excellent photovoltaic performance.…”

Magnetron sputtered ZnO electron transporting layers for high performance perovskite solar cells

“…Meanwhile, it is shown that the as-obtained ZnO films show high transmittance >90% in the visible-near infrared region, superior to that of the bare FTO substrate; this scenario might be associated with the lower surface roughness of sputtered ZnO films, which affords reduced light scattering and light trapping for improved straight transmittance. 38 The superior light transmittance of ETLs is favorable for the enhanced light harvesting of the absorber layer.…”

Theoretical Insight into High‐Efficiency Triple‐Junction Tandem Solar Cells via the Band Engineering of Antimony Chalcogenides

“…The bandgap of the Sb 2 (S 1− x Se x ) 3 photoactive layer can be adjusted continuously by changing the ratio of the Se content ( x ), because the crystal structures of Sb 2 S 3 and Sb 2 Se 3 are isomorphic. [ 18–29 ] Vacuum and non‐vacuum methods have been successfully used to prepare Sb 2 (S 1− x Se x ) 3 thin films. The vacuum method generally utilizes a thermal evaporation process.…”

“…[17] The bandgap of the Sb 2 (S 1Àx Se x ) 3 photoactive layer can be adjusted continuously by changing the ratio of the Se content (x), because the crystal structures of Sb 2 S 3 and Sb 2 Se 3 are isomorphic. [18][19][20][21][22][23][24][25][26][27][28][29] Vacuum and non-vacuum methods have been Antimony chalcogenides have become a family of promising photoelectric materials for high-efficiency solar cells. To date, single-junction solar cells based on individual antimony selenide or sulfide are dominant and show limited photoelectric conversion efficiency.…”
