摘要： A photovoltaic cell having multiple stacked layers has a thickness from the top of its top layer to the bottom of its bottom layer of less than one micron. Metal conducting layers are positioned between semiconductor layers with semiconductor layers having higher bandgaps being located above semiconductor layers having lower band gaps. The layers of the photovoltaic cell are arranged and stacked, and the thicknesses and materials for the semiconductor layers and conductive layers are selected to realize desired absorption, transmission, and reflection characteristics. The geometry and thicknesses of the respective layers of the cell allows incident light of various angles to be absorbed by all of the semiconductor layers of the cell.
