New development of solar temperature difference power generation

What is the relationship between air temperature and photovoltaic power generation?

The temperature of lake is higher (1.6 °C) than land, and the photovoltaic power generation is the same as the characteristic of the temperature (798 kW h). There is a non-linear relationship between air temperature, solar radiation and photovoltaic power generation.

How does temperature affect the performance of solar photovoltaic modules?

In terms of temperature, the temperature of solar photovoltaic modules will affect the performance of the photovoltaic system, which is mainly manifested in the reduction of photoelectric conversion efficiency and the abatement of photovoltaic power generation [27 ].

What is solar thermoelectric generation?

Solar radiation is one potential abundant and eco-friendly heat source for this application, where one side of the thermoelectric device is heated by incident sunlight, while the other side is kept at a cooler temperature. This is known as solar thermoelectric generation.

How does solar radiation affect power generation?

Power generation presents a stair-like distribution with the increase of solar radiation. The air temperature 15 °C is a critical point. When the temperature is lower than 15 °C, the power generation is more sensitive to changes in solar radiation.

Is there a unified relationship between power generation and solar radiation?

Namely, there is no unified relationship between power generation and solar radiation and temperature.

What is the difference between photovoltaic and thermoelectric energy conversion?

The photovoltaic effect directly converts light into electricity, whereas the thermoelectric effect converts temperature differences into electrical energy. In a PV-TE system, the thermoelectric module is integrated with the tandem perovskite silicon solar cell to collect the waste heat generated during solar energy conversion.
