Photovoltaic cell package assembly for mechanically stacked photovoltaic cells
This patent describes an apparatus comprising mechanically stacked solar cells, comprising: a base support having opposed major surfaces; a first heat spreader-electrical contact contacting the base support on a major surface thereof which is incident to solar radiation; means for electrically contacting the first heat spreader-electrical contact; a first insulating spacer surrounding the heat spreader-electrical contact, the first insulating spacer having a space therein for a photovoltaic cell; a first photovoltaic cell having opposed major surfaces and electrically contacting the heat spreader-electrical contact on its major surface opposed to solar radiation, the first photovoltaic cell having a band gap energy responsive to solar radiation of predetermined wavelengths; means for electrically contacting the other major surface of the first photovoltaic cell which is incident to solar radiation; a second insulating spacer contacting the first insulating space and having a space therein for a second photovoltaic cell; and a second photovoltaic cell having, opposed major surfaces, the second photovoltaic cell having a band gap energy responsive to solar radiation of shorter wavelengths than the first photovoltaic cell.
