It can be seen that the photothermal conversion efficiency of PA/SEBS/CNT-10 % is the highest at 750 W/m 2 light intensity, which is 96.17 %. In other light intensity, the conversion efficiency of light and heat is >94 %. The peak temperature increases with the
Abstract. Semiconducting single-walled carbon nanotubes (s-SWCNTs) have the potential as light to heat efficiency, recently known as photothermal conversion efficiency (η), for photothermal therapeutic applications since they exhibit strong absorption in the near-infrared region (NIR).We report experimental studies of light to heat efficiency of two …

The combination of wood and phase change energy storage materials (PCMs) can improve the phase change latent heat and temperature adjustment time of wood [[7], [8], [9]]. According to the form of heat storage, PCMs can usually be divided into solid-solid, solid-liquid, liquid-gas and solid-gas type, etc. [10, 11]. Solid-liquid PCMs …

However, in terms of photo-thermal conversion and storage by PCMs, as presented in Table 1, the majority of the open literature only considers the latent heat to calculate the photo-thermal conversion efficiency, which cannot reflect the actual photo-thermal conversion performance of PCMs during the whole energy conversion and …
Moreover, a high thermal conductivity is desirable in PCM for achieving faster solar heat storage/release efficiency. Mishra et al. [22], [23], [24] presented that carbon black can significantly improve the thermal conductivity of PCMs because of the formation of quasi-2D percolation networks after using a high concentration of carbon …

The efficiency for the conversion of electricity to light can be defined as the ratio of the energy converted to light to the electrical energy consumed. For example, common incandescent lightbulbs convert about 5% of the electrical energy they consume to light; the rest of the energy consumed is dissipated as heat, which adds to the cooling ...
