6 FAQs about [What does solar thermochemistry mean ]
Can solar energy be converted into thermal energy?
In addition to electrical energy, solar energy can also be initially converted into thermal energy for thermochemistry (TC), which we term it as Light–Heat–Chemistry (L–H–C).
How does solar energy affect chemical reactions?
In this way, the photons with higher energy can drive the chemical reactions, while the rest of energy can be collected in the form of heat, enabling the cascade utilization of full-spectrum solar radiation.
Can solar energy be used for heating?
According to the second law of thermodynamics, heat generation will increase irreversible losses and reduce the quality of energy. Considering the potential of high-energy photons, it seems somewhat “wasteful” to use the whole solar spectrum for heating.
Should solar thermal power generation devices be modified for PTC processes?
Since solar thermal power generation is a mature technology and has been widely applied, modifying solar thermal power generation devices for PTC processes is a feasible solution, which can integrate with heat collection and meet the temperature requirement for the PTC processes in the meantime.
Why are photovoltaic cells used in photochemical process?
On the one hand, the photons with much higher energy than the Eg of photovoltaic cells are used in the photochemical process, decreasing the irreversible losses of high-energy photons. On the other hand, the photons with lower energy than the Eg are recycled to provide heat for the thermochemical process.
What is solar-driven chemistry?
Thus, solar-driven chemistry is an attractive way to solve the two problems. Photothermal chemistry (PTC) is developed to achieve full-spectral utilization of the solar radiation and drive chemical reactions more efficiently under relatively mild conditions.
