摘要:
The present invention is a thick film silver composition for use a solar cell device. The thick film paste composition comprises an electrically conductive silver powder, one or more glass frits, a nano-sized additive wherein the nano-sized additive is selected from metallic zinc, zinc alloys or a mixture of metallic zinc and zinc oxide, all dispersed in an organic medium.
摘要:
The present invention relates to screen-printable quaternary chalcogenide compositions. The present invention also provides a process for creating an essentially pure crystalline layer of the quaternary chalcogenide on a substrate. Such coated substrates contain p-type semiconductors and are useful as the absorber layer in a solar cell.
摘要:
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.

The present invention relates to screen-printable quaternary chalcogenide compositions. The present invention also provides a process for creating an essentially pure crystalline layer of the quaternary chacogenide on a substrate. Such coated substrates contain p-type to semiconductors and are useful as the absorber layer in a solar cell.
摘要:
The present invention relates to synthesis of copper zinc fin sulfide, Cu2ZnSnS4(CZTS) in an ionic liquid, using a mixture of copper-containing sulfides, zinc-containing sulfides, and tin-containing sulfides. Cu2ZnSnS4 is useful as an absorber material in thin film solar cells.
摘要:
Provided are compositions derived from a polycarboxylic acid, water soluble blue dyes and blue pigments in a fixed weight ratio. The compositions can be used to prepare thermal transfer donor elements that can be used to make blue pixels of a color filter element with improved surface characteristics and lightfastness.
摘要:
The present invention relates to a new method of cross-coupling aryl moieties comprising reacting an arylhalide with an arylboronic acid in the presence of a palladium compound and a compound comprising a di-alkylphosphine moiety.
摘要:
Disclosed herein are compositions derived from a polycarboxylic acid, and an ionic liquid. The compositions can be used to prepare thermal transfer donor elements.
摘要:
Divalent germanium and tin compounds are provided. The divalent germanium and tin compounds have been found to be efficient catalysts for the formation of polyurethanes. Methods for making polyurethanes using the catalysts are also provided.
