Multi-stacked transparent-electrode for transparent photovoltaics

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.

Automated summary

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.
