Solar cell with increased efficiency and method for increasing the efficiency
摘要
#CMT# #/CMT# The solar element has vertical converters (3a - 3c) absorbing an electromagnetic radiation with frequencies and emitting the radiation with another frequency. Selective reflective structures (9a - 9c) reflect a part of the impinging electromagnetic radiation and transmitting the part of the impinging radiation. A luminance unit (2) is arranged adjacent to the reflective structures that are arranged adjacent to the vertical converters. The vertical converters are arranged adjacent to a solar cell (1). #CMT# : #/CMT# An independent claim is also included for a method for improving efficiency of a solar cell. #CMT#USE : #/CMT# Solar element. #CMT#ADVANTAGE : #/CMT# The solar element minimizes loss of highly-converted radiation by absorption. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic view of a solar element. 1 : Solar cell 2 : Luminance unit 3a - 3c : Vertical converters 5 : Mirror 9a - 9c : Reflective structures.
