摘要:
Disclosed herein are processes for making quaternary chalcogenide wafers. The process comprises heating a mixture of quaternary chalcogenide crystals and flux and then cooling the mixture to form a solidified mixture comprising ingots of quaternary chalcogenide and flux. The process also comprises isolating one or more ingots of quaternary chalcogenide from the solidified mixture and mounting at least one ingot in a polymer binder to form a quaternary chalcogenide-polymer composite. The process also comprises optionally slicing the quaternary chalcogenide-polymer composite to form one or more quaternary chalcogenide-polymer composite wafers. The quaternary chalcogenide wafers are useful for forming solar cells.

Disclosed herein are processes for making quaternary chalcogenide wafers. The process comprises milling quaternary chalcogenide crystals to form milled particles, and then compressing the milled particles to form a quaternary chalcogenide wafer. The quaternary chalcogenide wafers are useful for forming solar cells.

Processes for making ivalent germanium and tin compounds are provided. The divalent germanium and tin compounds have been found to be efficient catalysts for the formation of polyurethanes.
摘要:
Ethylene and allyl- or vinylsilanes are efficiently copolymerized by certain late transition metal complexes containing selected bidentate or tridentate ligands. The resulting novel polymers may be crosslinked by moisture when vinylsilane contains groups bound to silicon which are hydrolyzable. The polymers are useful for wire coating, crosslinked foams, pipes, and other uses.

The present invention relates to synthesis of copper zinc tin sulfide, Cu2ZnSnS4. Copper zinc tin sulfide is useful as an absorber material in a thin film solar cell application.
摘要:
Higher molecular weight linear α-olefins are produced by the oligomerization of ethylene using certain iron complexes of 2,6-diacylpyridinedimimines or 2,6-pyridinedicarboxaldehydedimines as catalysts. These iron complexes are more sterically hindered than those heretofore used. The resulting α-olefins are useful as comonomers in olefin polymerizations.
