Original abstract
Abstract Single-junction solar cells are widely installed but have low conversion efficiency limits. Multi-junction solar cells achieve high conversion efficiency but are expensive and require concentrator tracking systems. Liquid crystals (LC) can be used as gradient refractive index (GRIN) lenses, allowing refractive index (RI) control via applied voltage. LC GRIN lenses that accept multiple oblique-incident light can realize high-efficiency flat-panel concentrator tracking photovoltaic system. Previous research proposed prototyped oblique-incidence LC GRIN lenses. This study investigated the relationship between the required optical path length RI and director calculated RI. The director calculated RI is calculated from the LC director. The optical path length RI is calculated using the optical path length toward the focal point. We clarified the fundamental conditions for the optical efficiency achieved with the current design for a focal length of 1100 μm
