聚光光伏与温差联合发电装置的研究

Research on concentrating photovoltaic and photovoltaic/thermal cogeneration systems

针对太阳能量利用率较低的现状,设计了基于砷化镓多结太阳能电池、半导体温差发电片的聚光光伏与温差联合发电装置.通过测量得出单独聚光光伏发电模块在几何聚光比为75时光电转换效率最大,达31.87%;而在加了半导体温差发电模块之后在几何聚光比为112时系统光电转换效率达32.81%,提高了整体光能量转化电能效率.

To avoid the current inefficient use of solar energy, cogeneration power device was provided. This device was based on concentrating photovoltaic and photovoltaic/thermal cogeneration. When using only concentrating photovoltaic system, the maximum photoelectric conversion efficiency was 31.87% where the geometric concentrating ratio was 75. However, the largest photoelectric conversion efficiency was 32.81% in the concentrating photovoltaic and photovoltaic/thermal cogeneration system where the geometric concentration ratio was 112. This cogeneration system increased the overall photoelectric conversion efficiency.
