A solar panel includes a silicon cells submodule of silicon based cells, a front transparent plate and a backsheet. The backsheet is arranged with at least a first conductive pattern that is connected to rear surface electrical contacts on each of the silicon cells. A thin film photovoltaic submodule is arranged between the front transparent plate and the silicon cells, and includes thin film cells in an arrangement with two photovoltaic submodule contacts that connect to a second conductive pattern on the backsheet. The backsheet is arranged for four-terminal wiring with the first pattern for the silicon cells and the second pattern for the thin film cells. The thin film cells are disposed in a first group of cells and in at least a second group of cells, each connected in series. The first group is connected in parallel with the second group, between the photovoltaic submodule contacts.

A photovoltaic device () is provided with a first electrode layer (), a photovoltaic layer (), a second charge carrier transport layer () and a second electrode layer (). The photovoltaic device () has a plurality of mutually subsequent photovoltaic device cells (A, . . . ,F) arranged in a first direction (D). Each pair of a photovoltaic cell (C) and its successor are serially connected in an interface region (CD). The interface region comprises an elongate region (R) between successive first electrode layer portion (C,D), a first elongate region (R) between successive photovoltaic layer portions (A,B), a second elongate region (R) between successive second charge carrier transport layer portions (C,D) and a third elongate region (R) between successive second electrode layer () portions (C,D). The second elongate region (R) extends within the first elongate region (R), and its lateral boundaries are distinct from those of the first elongate region (R).

Photovoltaic device and method of manufacturing the same

A tandem solar cell includes a top solar cell and a bottom solar cell. The top solar cell and the bottom solar cell each have a respective front surface and a rear surface, with the respective front surfaces being adapted for facing a radiation source during use. The top solar cell is arranged with its rear surface overlying the front surface of the bottom solar cell. The top solar cell includes a photovoltaic absorber layer with a bandgap greater than that of crystalline silicon. The bottom solar cell includes a crystalline silicon substrate. On at least a portion of the front surface of the bottom solar cell a passivating layer stack is disposed which includes a thin dielectric film and a secondary layer of either selective carrier extracting material or polysilicon. The thin dielectric film is arranged between the silicon substrate and the secondary layer.
