SOLAR PANEL WITH FOUR TERMINAL TANDEM SOLAR CELL ARRANGEMENT

摘要

A solar panel (1) includes a silicon cells submodule (14) of silicon based cells, a front transparent plate (10) and a backsheet (16). The backsheet is arranged with at least a first conductive pattern (161) that is connected to rear surface electrical contacts on each of the silicon cells. A thin film photovoltaic submodule (12) is arranged between the front transparent plate and the silicon cells, and includes thin film cells (22) in an arrangement with two photovoltaic submodule contacts (VI, V2) that connect to a second conductive pattern (162) 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 (24) and in at least a second group of cells (26), each connected in series. The first group is connected in parallel with the second group, between the photovoltaic submodule contacts.
