      abstract     = {We optically designed and investigated two deterministic
                      light-trapping concepts named “Hutong” (wafer thickness
                      dependent, patch-like arrangement of “V” grooves with
                      alternating orientations) and “VOSTBAT” (one directional
                      “V” grooves at the front and saw-tooth like structures
                      at the back) for the application in emerging thin silicon
                      heterojunction (SHJ) solar cells. Calculated photocurrent
                      density (Jph) (by weighting the spectrally resolved
                      absorptance with AM1.5g spectrum and integrating over the
                      wavelength) showed that both the Hutong and VOSTBAT
                      structures exceed the Lambertian reference and achieved Jph
                      of 41.72 mA/cm2 and 41.86 mA/cm2, respectively, on 60 μm
                      thin wafers in the case of directional, normal incidence.},
