      abstract     = {In recent years, luminescent solar concentrators (LSCs)
                      have gained a renaissance as a pivotal transparent
                      photovoltaic (PV) for building-integrated photovoltaics
                      (BIPVs). However, most of the studies focused on
                      light-selective LSCs, and less attention was paid to the
                      utilization of the full solar spectrum. In this study, a
                      lead-free microcrystal Cs2AgxNa1–xBiyIn1–yCl6 (CANBIC)
                      perovskite phosphor is demonstrated to have bifunctional
                      effects of luminescent down-shifting (LDS) and light
                      scattering for the fabrication of LSCs, realizing light
                      response from ultraviolet (UV) to NIR regions by an
                      edge-mounted Si solar cell. The optimized CANBIC content (30
                      mg) in an LSC realizes the best optical efficiency (ηopt)
                      of $5.40\%$ and an average visible transmission (AVT) of
                      $>50\%.$ This contributes to the improvement in short
                      circuit current density (JSC) up to 1.232 mA/cm2 for the
                      LSC–PV system (one-edge mounted Si solar cell) as a result
                      of the best power conversion efficiencies (PCEs) of
                      $0.463\%$ and $1.852\%$ for the LSC–PV and LSC–4PV
                      systems (four-edge mounted Si solar cells), respectively. An
                      Al foil is applied as a reflection background in the
                      LSC–4PV system, and a champion PCE of $3.14\%$ is realized
                      due to an improved JSC of up to 7.94 mA/cm2 in total.
                      Furthermore, the LSC maintains superior stability under
                      exposure to continuous ultraviolet illumination or in
                      ambient air.},
