Development of Chalcogenide Perovskites(ABS3) for Pb-free, Stable and Efficient Perovskite Solar Cells

BaZrS31的合成固态合成BaZrS3：将BaS和ZrS2与硫脲（TU）一起研磨，在250℃-350℃左右加热，得到黑色粉末。但XRD分析没有发现与BaZrS3.2匹配的峰。溶剂热合成：BaCl2， ZrCl4和硫脲在不同溶剂体系和不同温度下的合成。BaCl2 +Z2Cl4+ TU在己烷（热压釜）中：XRD未发现与BZrS3匹配的峰。BaCl2 +Z2Cl4+ TU在乙醇和水（在高压釜中）：黑色，但得到无定形粉末。BaCl2+ZrCl4+TU中的乙二胺（EDA）（高压釜）：黑色粉末但无定形BaS + ZrS + EDA +乙烯二硫醇（EDT）（高压釜，180℃）：黑色粉末但无定形。BaCl2+ ZrCl4 +TU在DMSO（高压釜，230oC/40h）：黑色粉末，但无定形

Synthesis of BaZrS31.Solid-state synthesis of BaZrS3: grinding BaS and ZrS2 together with and without thiourea (TU) and heating the mix powder at around 250oC-350oC, black powder resulted. However, XRD analysis showed no peaks matching with BaZrS3.2.Solvothermal synthesis: BaCl2, ZrCl4 and thiourea in different solvent systems and at different temperatures. BaCl2 +Z2Cl4+ TU in hexane (autoclave): XRD shows no peaks matching with BZrS3. BaCl2 +Z2Cl4+ TU in Ethanol and water (in an autoclave): black color but amorphous powder was obtained. BaCl2+ZrCl4+TU in ethylene diamine (EDA) (autoclave): black powder but amorphous BaS + ZrS + EDA + ethylene dithiol (EDT) (autoclave, 180oC) :black powder but amorphous. BaCl2+ ZrCl4 +TU in DMSO (autoclave, 230oC/40h): black powder but amorphous
