论文摘要
气候变化及其许多相关的影响是全球最关键的挑战之一。通过发电,Photovoltaics在减轻Co $ _2 $的情况下发挥了作用。但是,将全球变暖限制为1.5 $^\ Circ $ C的目标越来越需要其他方法。该论文介绍了如何设计光伏表面,以扭转地球辐射失衡,从增加的温室气体导致全球温度较高的温室气体。新的PV表面会产生电力,反映了子带间隙辐射,最大程度地减少其温度,产生热辐射并通过大气发射更多IR,这些过程总计650 wm $^{ - 2} $。这是由以下方式实现的:(1)工作温度下的PV系统效率$> $> $ 20 \%和150 wm $^{ - 2} $的子频段间隙反射总计350 wm $^{ - 2} $(2} $(2)热发射辐射(辐射冷却)150 wm $^{ - 2} $^{ - 2} $; (3)通过大气窗口以1.5 $μ$的150 wm $^{ - 2} $进行主动红外排放。使用这样的PV表面,我们表明10个已安装的PV可以逆转全球变暖。使用PV平衡全球温度会引入PV的其他注意事项,重点是高效,尤其是在工作温度,辐射冷却和新工艺方面的高效率,以1.5 $ $ $排放。我们发现,根据其设计,PV面板可以升高或降低全球温度。
Climate changes and its many associated impacts are one of the most critical global challenges. Photovoltaics has been instrumental in mitigation of CO$_2$ through the generation of electricity. However, the goal of limiting global warming to 1.5 $^\circ$C increasingly requires additional approaches. The paper presents how PV surfaces can be designed to reverse the Earth's radiative imbalance from increased greenhouse gasses that lead to higher global temperatures. The new PV surface generate electricity, reflect sub-band gap radiation, minimize their temperature, generate thermal radiation and emit additional IR through the atmospheric, with these processes totaling 650 Wm$^{-2}$. This is realized by: (1) PV system efficiency at operating temperature $>$ 20 \% and sub-band gap reflection of 150 Wm$^{-2}$ for a total of 350 Wm$^{-2}$ (2) Thermally emitted radiation (radiative cooling) of 150 Wm$^{-2}$; and (3) Active IR emission through an atmospheric window at 1.5 $μ$ of 150 Wm$^{-2}$. With such PV surfaces, we show that 10 TW of installed PV can reverse global warming. Using PV to balance global temperatures introduces additional considerations for PV, focusing on high efficiency, particularly high efficiency at operating temperatures, radiative cooling, and new processes for 1.5 $μ$ emission. We find that depending on their design, PV panels can increase or decrease global temperatures.
