Undoped tin dioxide transparent electrodes for efficient and cost-effective indoor organic photovoltaics (SnO2 electrode for indoor organic photovoltaics)
Indium-free un-doped tin dioxide (SnO2) serves as a transparent conducting electrode for indoor organic photovoltaics (OPVs). SnO2 OPV systems demonstrate superior indoor performance compared with indium tin oxide (ITO)-based systems. SnO2-based OPV systems shows 14.6% efficiency under 1000 lx of LED illumination. Low-cost SnO2 can be a promising substitute for expensive ITOs in indoor OPV systems.
