Carbon nanotube reinforced cu metal matrix composites for current collection from space photovoltaics

摘要: There is a strong desire to reduce the weight and increase power output of photovoltaics devices for space applications while simultaneously reducing cost. The inverted metamorphic multijunction (IMM) cell an advanced III–V device architecture that provides routes higher on-orbit production. A specific provided by combination high efficiency thin, low-weight device. As crystalline become thinner, however, they are more prone fracture/cleaving failure. In most benign case, fracture may simply disconnect portion from providing circuit. More seriously, can also lead open string. These problems be mitigated development fracture/cleave-tolerant devices. this paper we consider novel fabrication route form metal matrix composites (MMCs) comprised carbon nanotubes embedded in metals such as Ag Cu. MMCs will used fabricate grid-lines back-metal layers IMM cells with goal maintaining active area even after fracture/cleavage failures.
