Abstract
A multi-terminal photovoltaic module includes an upper photovoltaic device which has a first upper electrode, an overlying upper absorber layer, an overlying upper window layer, and a second upper electrode. The upper absorber layer has an upper band gap in a first band gap range. The module also includes a lower photovoltaic device which has a first lower electrode, an overlying lower absorber layer, an overlying lower window layer, and a second lower electrode. The lower absorber layer has a lower band gap in a second band gap range. The module also includes a bonding material coupling the second upper electrode and the first lower electrode. Moreover, the module includes a first upper terminal coupling the first upper electrode and a second upper terminal coupling the second upper electrode. The module further includes a first lower terminal coupling the first lower electrode and a second lower terminal coupling the second lower electrode. In an embodiment, the module provides a first open circuit voltage provided between the first upper electrode and the second upper electrode and a second open circuit voltage provided between the first lower electrode and the second lower electrode. In an embodiment, the first open circuit voltage is different from the second open circuit voltage.
