Keywords:Wavelength-conversion, wafer bonding, multijunction solar cell

Wavelength-conversion material-mediated semiconductor wafer bonding has been demonstrated by utilizing an adhesive and viscous organic matrix embedding fluorescent particles. This scheme is expected to enhance solar cell efficiency and structure flexibility by photon management and current matching among subcells, and light source and detector performance in hybrid photonic integrated circuits by the delivery of preferred frequencies to each of gain/absorber and waveguide materials.
