Solar cell
摘要:
The invention relates to a solar cell including a first layer having a checkered layout of fields having a photovoltaic layer and fields having at least a reflective layer; a second layer arranged above and spaced apart from the first layer, which second layer has a checkered layout of fields having a photovoltaic layer and of openings, with the openings of the second layer registered with the fields having a photovoltaic layer of the first layer; a burning glass layer arranged above and spaced apart from the second layer, with the fields having a photovoltaic layer of both the first and second layer as well as the fields having at least a reflective layer facing the burning glass layer; and a third layer arranged between the first and second layer, preferably arranged to the second layer, which third layer has a checkered layout of fields having a photovoltaic layer and of openings, with the openings of the third layer registered with the openings of the second layer and with the fields having a photovoltaic layer of the third layer facing the first layer.
