Transparent photovoltaics utilize light to generate electric power and have the potential to be used in transparent windows as invisible power generators. By using multi-stacked transparent-electrode (MTE) with Ni film, improvements in open-circuit voltage and short-circuit current density have been achieved. The functional transparent-electrode is a key factor in enhancing TPV performance with minimal trade-offs in transmittance.
Transparent photovoltaics are the solar cells to generate electric-power from the light. Due to the high transparency, TPV has a high potential to be adopted in the transparent windows, as the invisible power generator. To improve the TPV performance, multi-stacked transparent-electrode (MTE) was designed having Ni film in two indium-tin-oxide layers. Ni-5 nm MTE shows prominently improvement to drive the high open-circuit voltage (V-oc = 0.507 V) and short-circuit current density (J(sc) = 3.00 mA/cm(2)), resulting in power-conversion-efficiency of 0.45% under AM 1.5G illumination. The functional transparent-electrode is a pivotal scheme to enhance TPV performance with less trade-off in transmittance. The TPV has the high potential to be applied in the transparent electronics and windows as the invisible power generator. (C) 2021 Elsevier B.V. All rights reserved.
