An innovative solar generation system integrates photovoltaic, thermoelectric, and energy storage technologies for continuous, all-day power generation

The floating power generation system in this invention harnesses both the visible spectrum (via photovoltaic (PV) panels) and the infrared spectrum (via thermoelectric (TE) power generation devices) of solar energy to produce electricity. Additionally, solar thermal energy absorbed during the day is stored for continuous power generation at night, ensuring a prolonged power supply. This system is versatile, suitable for use on water surfaces and in regions with substantial day-night temperature fluctuations, such as the desert.

This invention employs an innovative combination of PV and TE modes to generate electricity. 

The heat source attains high temperatures by focusing sunlight with a custom-designed Fresnel lens, enhancing the performance of thermoelectric generator (TEG), as higher TEG temperatures yield greater efficiency. 

The TE cold end achieves a significant temperature difference by direct heat sink contact with water or by using custom-made TEGs with specific aspect ratios. 

Incorporating phase change energy storage technology, the system can release stored heat at night to facilitate 24-hour power generation. 

The high-efficiency TEG module maximizes thermal energy utilization, resulting in superior power generation efficiency.
