PHOTOVOLTAIC DEVICES WITH HIGH WORK-FUNCTION TCO BUFFER LAYERS AND METHODS OF MANUFACTURE

摘要

Embodiments of the invention are directed to photovoltaic cells comprising a substantially optically transparent buffer layer on a superstrate and a photoabsorber layer on the buffer layer. The buffer layer of detailed embodiments has a work function greater than or equal to about the work function of the photoabsorber layer. Additional embodiments of the invention are directed to photovoltaic modules comprises a plurality of photovoltaic cells and methods of making photovoltaic cells and photovoltaic modules.
