III–V Multijunction Solar Cell Integration with Silicon: Present Status, Challenges and Future Outlook

Abstract: Achieving high-efficiency solar cells and at the same time driving down the cell cost has been among the key objectives for photovoltaic researchers to attain a lower levelized cost of energy (LCOE). While the performance of silicon (Si) based solar cells have almost saturated at an efficiency of~25%, III-V compound semiconductor based solar cells have steadily shown performance improvement at~1% (absolute) increase per year, with a recent record efficiency of 44.7%. Integration of such high-efficiency III-V m… Show more

“…However, the large scale deployment of these devices for terrestrial application has been limited by their high costs. One of the most significant cost contributors to the III–V solar cells is the lattice matched substrate, which is typically GaAs or Ge . In order to avoid the high substrate cost, a GaAs solar cell with efficiency of 28.8% was developed by Alta Device with epitaxial lift‐off technology .…”
