Description

Technical field: [0001] The invention relates to a photovoltaic power generation combination system. Background technique: [0002] The existing photovoltaic power generation system is to directly connect the electric energy generated by multiple photovoltaic modules to the grid after being converted by the inverter. This product is suitable for large-scale solar power generation systems, but not suitable for AC and DC plug-and-play distributed photovoltaic systems. [0003] Quantum dots, also known as nanocrystals, are nanoparticles composed of II-VI or III-V elements. The particle size of quantum dots is generally between 1 and 10nm. Quantum dots have a wide excitation spectrum and Narrow emission spectrum. Quantum dot emission spectrum can be controlled by changing the size of quantum dots. By changing the size of quantum dots and its chemical composition, the emission spectrum can cover the entire visible light region. Taking CdTe quantum as an example, when its particle...
