MOLYBDENUM SUBSTRATES FOR CIGS PHOTOVOLTAIC DEVICES

摘要

Photovoltaic (PV) devices and solution-based methods of making the same are described. The PV devices include a CIGS-type absorber layer formed on a molybdenum substrate. The molybdenum substrate includes a layer of low- density molybdenum proximate to the absorber layer. The presence of low- density molybdenum proximate to the absorber layer has been found to promote the growth of large grains of CIGS-type semiconductor material in the absorber layer.
