Efficiency of soft solar cloth power generation

Highly efficient solar steam generation from activated carbon fiber cloth with matching water supply and durable fouling resistance.

These demonstrations provide clear evidence of the utility of the solar energy harvesting fabric technology within regular clothing as a power source for wearable devices which have a power requirement around tens to few hundreds of milliwatts, which is typical for most wearable devices.

Harvesting solar energy for photothermal conversion in an efficient manner for steam-electricity cogeneration is particularly opportune in the context of comprehensive solar utilization to address .

To address the challenges of generating stable electricity over a prolonged duration in MEG and the requirement of liquid water for WEG, and to obtain satisfactory electrical performance output, we have developed a lightweight and thin moisture absorption-evaporation power generation fabric (Fig. 2D).

Here, a new system for solar steam generation is fabricated based on a PEGylated MoS 2-cotton cloth (PMoS 2-CC). 80.5–90 ± 3.5% of high-efficiency solar steam generation is achieved under a light density of 1–5 kW m –2 because of the good gas permeability of CC and the hydrophilic property of PMoS 2-CC.

6 FAQs about [Efficiency of soft solar cloth power generation]

Can self-floating Janus cotton fabric be used for solar steam generation?

Inspired by lotus leaves, self-floating Janus cotton fabric is successfully fabricated for solar steam generation with salt-rejecting property. The layer-selective soot-deposited fabrics not only act as a solar absorber but also provide the required superhydrophobicity for floating on the water.

How much power does a power generation fabric produce?

In addition, the power generation fabric generates a current output of 0.256 mA and maintains a current output of 10 μA even after a month of continuous power generation. The high performance and sustainability are attributed to the moisture absorption-evaporation structure and continuous ion supply.

Is a sustainable moisture absorption-evaporation cycling fabric a promising technology for power generation?

Collecting energy from the ubiquitous water cycle has emerged as a promising technology for power generation. Here, we have developed a sustainable moisture absorption-evaporation cycling fabric (Mac-fabric).

How can a fabric structure be designed for hydrovoltaic power generation?

Second, the fabric structure can be easily designed with controllable moisture conductivity, such as a fabric with single moisture conductivity (23, 24), which is beneficial to the structural design of water diffusion in hydrovoltaic power generation.

How a solar steam generator works?

Meanwhile, the solar steam generator with the increasing height can absorb energy from adjacent ambient air to strengthen the vapor generation.

How to create sustainable power generation of Mac-fabric?

Continuous water flows through the electronegative micro-/nanochannel to realize the sustainable power generation of Mac-fabric. Secondly, inspired by the use of inorganic salts to enhance plant evaporation power generation, we chose aluminum electrodes and carbon belts as asymmetric electrodes.
