According to some aspects, an apparatus for converting electromagnetic radiation into electric power is provided, comprising a first layer comprising a first semiconductor material, an absorber in contact with the first layer, a second layer comprising a second semiconductor material, the second layer being in contact with the absorber, and a reflector to reflect at least a portion of electromagnetic radiation passing through the second layer. According to some aspects, a method of forming an apparatus for converting electromagnetic radiation into electric power is provided, comprising forming a reflector on a substrate, forming a first layer in contact with the reflector, the first layer comprising a first semiconductor material, forming an absorber in contact with the first layer, and forming a second layer in contact with the absorber, the second layer comprising a second semiconductor material. |
