When you think of solar energy, you can probably imagine photovoltaic panels that collect sunlight to turn it into electricity. But there are other ways to use the power of the sun. One method of growing interest is called concentrated solar thermal energy, or CSP, which uses mirrors to reflect and concentrate solar energy.
Compared to other renewable energy sources, CSPs have been hampered by technical challenges and a lack of funding and government incentives. However, as the urgency to replace fossil fuels continues to grow, increasing the demand for carbon-free energy, many increasingly funded entities are seeking to improve their technology. Proponents argue that the heat generated by CSP systems and their storage capacity offer advantages over other renewable energy sources for generating grid-based electricity and powering various industrial processes.
The energy obtained from the one-off conversion of sunlight by different technologies, resulting in a usable form of energy, is called direct solar energy. Electricity collected by solar panels is one example of direct solar energy.
Which type of concentrated solar power panel gives the high temperature?

Why does temperature affect solar cell efficiency? See the article : Action solar san diego.
Not to get into the calculations too much, but if your solar panels are exposed to higher temperatures, the current will increase while the voltage will decrease. As the voltage drops faster as the current increases, the efficiency of your solar panels will decrease.
Does temperature affect solar panel efficiency?
The main effect of temperature on solar panels is that it reduces the efficiency of solar cells in converting solar energy (sunlight) into electricity. In other words, chemical reactions in solar panels are more efficient at cooler temperatures than at hot ones.
Are solar panels more efficient when hot or cold?
The electrons are at rest (low energy) at cooler temperatures. When these electrons are activated due to an increase in sunlight (high energy), the solar panel achieves a larger voltage difference, which generates more energy. Therefore, solar panels produce electricity more efficiently in colder weather.
