摘要

In this work, a novel low-cost and high-efficiency, multi-junction solar cells architecture is proposed. It is expected this kind of design will provide a significant approach for the high-efficient, low-cost solar cells, which will promote the application of solar cells. A thin planar reflection-type diffractive optical element (DOE) has been designed to simultaneously focus and split the sunlight into several energy regions for lateral multi-junction solar cells. As a result, solar cells of different band-gaps are placed accordingly to match the corresponding spectrum region. The simulation results revealed that the DOE can successfully concentrate and split the sunlight into pre-designed postions, which thus generates "rainbow-like" pattern on output plane. The correspoding optical efficiency can reach a high level over 80%. In actural appliaction, low-cost and high-reflectivity materials will be chosed for the mass duplication of DOE. As a result, this work provides a significent approach for developing low-cost and high-efficency solar cells.
