Oxygen-deficient solar power generation temperature is too high

How does temperature affect PV power generation?

Considering from the perspective of light, the increase in temperature is beneficial to PV power generation, because it will increase the free electron–hole pairs (i.e., carriers) generated by the PV effect in the cell to a certain extent . However, excessively high temperature cannot increase the final output of the SC.

How does temperature affect power generation efficiency?

The temperature effect of SCs will affect the intrinsic properties of SC materials and the parameters that characterize SC performance. This will ultimately affect its power generation efficiency. This work reviews previous studies on temperature effects in SCs.

Why is the temperature distribution of a solar panel uneven?

In the application of SCs, due to some external conditions such as human operation or external shading, one part of the SC will be exposed to excessive light, and the other part will be exposed to very little light, causing uneven illumination, which will also lead to the temperature distribution of the SC is uneven.

How do environmental factors affect the power of a solar cell?

The effect of these environmental factors will eventually lead to the aging of the cell, which will reduce the power of the cell. In addition, PV efficiency and cell capacity degradation vary with time and cycle number, respectively .

Does high operating temperature affect cell efficiency?

Upper bounds on hybrid systems performance are established as a function of temperature and illumination level. Highly concentrated sunlight markedly diminishes photovoltaic, as well as thermal, efficiency losses at high temperature. The extent to which high operating temperature affects cell efficiency strongly depends on cell architecture.

Can electricity and heat storage help maintain hydrogen production and nominal operating temperatures?

Furthermore, as system capacity factor is often key to technological and economic feasibility, it would be promising to investigate the integration with electricity and heat storage technologies to maintain hydrogen production and nominal operating temperatures through periods of fluctuating or low DNI, or to enable 24-hour operation.
