Semitransparent and bifacial photovoltaic devices using very thin absorbers, which are sandwiched by transparent conducting front and rear contacts, provide efficient solar energy yields and partially visible transparency. These characteristics allow such devices to be used in applications including building-integrated photovoltaics (BIPV), solar vehicles, and wearable devices. In this study, we present the development of semitransparent and bifacial solar devices with ultrathin Cu(In,Ga)Se2 (CIGS) absorber layers of different film thicknesses (30–300 nm) via an optimized single-stage coevaporation process. The effects of deposition parameters on the PV performance and optical properties of the fabricated devices are investigated. We also examine the performance of these devices under low-light irradiance and bifacial illumination conditions. |
