Research abstract
The proposed SBIR will focus on the development of wafer bonding of GaAs and InP to produce a two junction tandem solar cell which will be the basis to realize a high efficiency solar cell with high manufacturing yield.The target efficiency of the two-junction solar cell is 40% at under AM0 illumination. The proposed wafer bonding process based on ELO wafers is expected to reduce the manufacturing cost of solar cell chips by at least 50% through the GaAs and InP substrate recycling, combined with a reduction in the solar cell thickness. This cost advantage will be obtained without any reduction in conversion efficiency. BENEFIT: This research would provide a foundation for lower cost, higher efficiency solar cells that could have wide benefits for space and terrestrial applications. The ability to remove the substrate along with wafer bonding would provide a clear pathway towards higher efficiency.
