Abstract

The invention relates to a dense-condensation photovoltaic cell array reducing mismatch loss, belongs to the technical field of solar energy utilization, and aims at reducing the mismatch loss of thedense cell array under non-uniform radiation and improving the power output of the dense cell array. The dense-condensation photovoltaic cell array of a rotational symmetry structure is divided into sub-modules in rotational symmetry, cells in each sub-module are connected in parallel, serial or full manner or a parallel, serial and full mixed manner, and the sub-modules are connected in series. Connection design with rotational symmetry characteristics enables that power loss caused by current and voltage mismatch of the dense cell array module of a large condenser can be reduced obviously under the real illumination condition with Gaussian or truncated cone-shaped distribution characteristics, power output of the cell array is further improved, and the efficiency, economical performanceand reliability of a dense-condensation photovoltaic cell array power generation system are improved.

Description

Technical field

[0001] The invention belongs to the technical field of solar energy utilization, and particularly relates to a dense concentrating photovoltaic cell array that reduces mismatch loss. Background technique

[0002] Currently, solar photovoltaic power generation has become the third largest renewable energy utilization method. Solar photovoltaic power generation system uses the photovoltaic effect of semiconductor materials to generate electricity, and has the advantages of high efficiency, no moving parts, and modularization of the system. Solar photovoltaic power generation systems are usually flat-panel photovoltaics, using thin-film cells or silicon cells, and the power generation efficiency is about 14-20%. The power generation system that adopts single-axis or multi-axis tracking type concentrating photovoltaic usually uses III-V cells or stacked cells, and the power generation efficiency can reach 25-35%, and the land area occupied by the power plant can be g...
