  • PHOTOVOLTAIC DEVICE
    Publication number: 20250056904
    Abstract: A photovoltaic device comprises at least two sub-cells, at least one connecting element electrically connecting adjacent sub-cells to one another, each sub-cell comprising: at least one segment; and at least one connecting element electrically connecting adjacent segments to one another in the event that a sub-cell has more than one segment; each one of the sub-cells having a unique bandgap and being arranged such that bandgaps of the sub-cells are in descending order with respect to a light incident surface of the photovoltaic device, each sub-cell being designed such that all segments of the photovoltaic device produce approximately the same current.
    Type: Application
