All-weather solar thermal power generation

What is the evaporation rate of all-weather electric and solar-thermal steam generation device?

In previous work, Yu et al. fabricated an all-weather electric and solar-thermal steam generation device with an evaporation rate of 11.73 kg m -2 h −1 by preparing wood-derived hydrophilic and porous carbon structures, generating grooves on their top surfaces and coating with hydrophobic carbon nanoparticles .

What is the evaporation rate of a self-made all-weather steam generator?

Finally, through the photothermal-electrothermal integrated system ( Scheme 1b and c ), the self-made all-weather steam generator achieves ultra-high evaporation rates of 8.04 and 11.70 kg m -2 h −1 under the irradiation of 5 V + 0.5 sun and 5 V + 1 sun, respectively, which is outstanding among similar products.

What are solar-based photothermal conversion materials (ptcms)?

Solar-based photothermal conversion materials (PTCMs) play a crucial role in solar steam generation, which needs to simultaneously satisfy the conditions of high broadband absorption of solar energy, fast upward transport of water molecules, low thermal conductivity in wet state, and good hydrophilic properties , .

How zctp aerogels can convert solar energy into heat?

On one hand, the device can directly convert solar into heat through PTC effect of ZCTP aerogels, and on the other hand, it can also convert the electrical energy stored in the solar panel into heat energy that required for water evaporation with ZCTP aerogels through electrothermal effect. Fig. 5.

Why is solar energy important?

Introduction Due to the gradual depletion of fossil energy and the increasing deterioration of environment, it is very urgent to develop clean and sustainable new energy to replace the fossil energy [1–3]. Solar energy is the largest energy source on our planet, which is clean, pollution-free and inexhaustible.

How C-WDFG is used to collect solar energy?

To collect the solar energy in sunny days, C-WDFG is coated on the hot end of a thermoelectric device. Photo of the CS/ PDMS composite film is shown in figure 6(a), which exhibits a black color. CS film without PDMS and graphene film, typical photothermal films, were also prepared for compar- ison.
