We describe stacked photovoltaic modules, and components thereof, in which at least one booster cell is combined with at least one primary cell in a stacked configuration. The booster cell may be in the form of a polycrystalline film disposed on a transparent substrate, such as a glass substrate, and the film may be patterned to form multiple booster cells. The booster cell includes an n-type layer and a p-type layer; the n-type layer may include polycrystalline zinc sulfide (ZnS), and the p-type layer may include polycrystalline zinc telluride (ZnTe). The n-type layer may have a band gap energy of at least 3.5 eV, and the p-type layer may have a band gap energy of at least 2 or at least 2.2 eV, or in a range from 2.2 to 2.3 eV. An intrinsic layer, also comprising polycrystalline ZnTe, may reside between the n-type and p-type layers.
Abstract:
The disclosure provides for a direct wafer bonding method including providing a bonding layer upon a first and second wafer, and directly bonding the first and second wafers together under heat and pressure. The method may be used for directly bonding an GaAs-based, InP-based, GaP-based, GaSb-based, or Ga(In)N-based device to a GaAs device by introducing a highly doped (A1)(Ga)InP(As)(Sb) layer between the devices. The bonding layer material forms a bond having high bond strength, low electrical resistance, and high optical transmittance.

Abstract:
A two-terminal voltage or current matched solar cell has up to four photovoltaically active junctions which efficiently convert solar radiation into electricity. The solar cell comprises GaInP (10"), GaAs (12"), and GaInAsP (15"), and in the four junction case, GaInAs (70") is used as well. The invention allows the solar spectrum to be converted into electricity more efficiently than previously (Fig. 3).
Abstract:
A photovoltaic device includes a plurality of photovoltaic cells disposed in an array in which each cell is adjacent to another cell. Each of the cells includes first and second photovoltaic modules. The first photovoltaic module of each cell is configured to convert a first part of light energy incident thereon into electrical energy and to reflect to the second photovoltaic module of an adjacent cell at least some of a remaining portion of light energy incident thereon. The second photovoltaic module of each cell is configured to convert into electrical energy the remaining portion of the light energy received from the first photovoltaic module of an adjacent cell.
