Abstract:
A composite photovoltaic structure having the following components is illustrated. A first photovoltaic unit is disposed on a transparent substrate, and electrically connected to a second photovoltaic unit in parallel, and the second photovoltaic unit is stacked on the first photovoltaic unit. The first photovoltaic unit is disposed on a second transparent electrode layer, and a first transparent conductive layer is disposed on a top of the first photovoltaic unit and electrically connected to a first transparent electrode layer, and the second photovoltaic unit is disposed on the first transparent conductive layer. A second transparent conductive layer is disposed on the second photovoltaic unit and is electrically connected to the second transparent electrode layer. Thus, the composite photovoltaic structure has a photoelectric reaction area of a significantly improved omnidirectional concentration gain, an efficiently induced current and a low manufacturing cost, without affecting the whole structure thickness.
