Problems solved by technology
With the continuous increase of the lens multiple, the current generated on the corresponding concentrating photovoltaic photoelectric conversion receiver is also increasing. The existing concentrating photovoltaic photoelectric conversion receiver can no longer satisfy the light collected by the lens of more than 500 times. The current demand that can generate electric energy; at the same time, the current generated on the concentrating photovoltaic cell chip cannot be guided out of the concentrating photovoltaic cell chip in a timely and uniform manner

Description
technical field [0001] The invention relates to a photovoltaic power generation component, in particular to a special receiver for high-current concentrating photovoltaic photoelectric conversion, which belongs to the technical field of solar power generation. Background technique [0002] The concentrated photovoltaic photoelectric conversion receiver is the core component of the concentrated photovoltaic power generation system, which is used to directly convert the light energy gathered by the lens into electrical energy. The larger the multiple of the lens, the fewer the number of concentrated photovoltaic cell chips used per unit area, and the lower the cost of the corresponding concentrated photovoltaic power generation system. More than a thousand times. With the continuous increase of the lens multiple, the current generated on the corresponding concentrating photovoltaic photoelectric conversion receiver is also increasing. The existing concentrating photovoltaic p...
