Abstract
Methods and apparatus are provided for converting electromagnetic radiation, such as solar energy, into electric energy with increased efficiency when compared to conventional solar cells. One embodiment of the present invention provides a photovoltaic (PV) device. The PV device comprises an absorber layer made of a compound semiconductor; and an emitter layer located closer than the absorber layer to a first side of the device. The PV device includes a p-n junction formed between the emitter layer and the absorber layer, the p-n junction causing a voltage to be generated in the device in response to the device being exposed to light at a second side of the device. Such innovations may allow for greater efficiency and flexibility in PV devices when compared to conventional solar cells.
