Description

technical field [0001] The invention relates to the field of solar energy applications, in particular to a light homogenizer, a light energy converter, a reflection and concentrating solar module, and a solar electric-heat hybrid utilization system. Background technique [0002] In the application of high-power concentrating solar energy, it is usually necessary to connect photovoltaic cells in series to increase the output voltage and reduce the output current, which requires balancing the working status of each photovoltaic cell, so that each photovoltaic cell in series can achieve higher efficiency at the same time. This requires that the input light of each photovoltaic cell be uniform, but when sharing the same reflective condenser, due to processing errors and control errors, it is difficult to achieve a stable and uniform concentrated spot. Contents of the invention [0003] The embodiment of the present invention provides a light homogenizer, a light energy convert...
