Abstract

Manganese2+-doped copper tin telluride nanoparticles (Mn2+:Cu2SnTe3 NPs), as an absorber layer, were grown using a chemical bath deposition (CBD) technique and demonstrated for solar cell applications. The cubical structure was formed on the WO3 surface with the band gap (Eg) of Cu2SnTe3 NPs decreased from 1.80 to 1.67 eV after Mn2+ doping. The photovoltaic property at 1 sun shows the efficiency (?) of 0.276%. The ? was increased with reducing sunlight intensity due to the lower carrier recombination process at an electrode and electrolyte interface, which leads to the increasing ?. The highest ? of 1.120% was yielded at 0.1 sun with a Jsc = 2.81 mA/cm2, a Voc = 0.148 V, a FF = 26.8%. It can be noted that this kind of material and a synthesis procedure can be feasibly further improved for a higher efficiency and more stability on an absorber layer.

Tin

Tin Bohr ModelSee more Tin products. Tin (atomic symbol: Sn, atomic number: 50) is a Block P, Group 14, Period 5 element with an atomic weight of 118.710. The number of electrons in each of tin's shells is 2, 8, 18, 18, 4 and its electron configuration is [Kr] 4d10 5s2 5p2. The tin atom has a radius of 140.5 pm and a Van der Waals radius of 217 pm.In its elemental form, tin has a silvery-gray metallic appearance. It is malleable, ductile and highly crystalline. High Purity (99.9999%) Tin (Sn) MetalTin has nine stable isotopes and 18 unstable isotopes. Under 3.72 degrees Kelvin, Tin becomes a superconductor. Applications for tin include soldering, plating, and such alloys as pewter. The first uses of tin can be dated to the Bronze Age around 3000 BC in which tin and copper were combined to make the alloy bronze. The origin of the word tin comes from the Latin word Stannum which translates to the Anglo-Saxon word tin.
