According to an embodiment, the present invention provides a solar cell. The solar includes a supporting layer that is characterized by a first thickness. The solar cell also includes a reflective layer overlying the supporting layer. The reflective layer is characterized by a second thickness. The reflective layer is attached to the supporting layer. The solar cell additionally includes a photovoltaic layer, which includes a first side and a second side. The photovoltaic layer is characterized by a third thickness. The photovoltaic layer includes a first side and a second side. The first side is opposite from the second side. The photovoltaic layer includes a first portion and a second portion. The first portion includes a fourth thickness from the first side. The second portion includes a fifth thickness from the second side. The first side of the photovoltaic layer is attached to the reflective layer. The first portion is characterized by a predetermined polarity. |
