Porous wood-carbonized solar steam evaporator

6 · Carbonized wood absorbs light more strongly than uncarbonized wood. Carbonized wood has a minimum efficiency of cross-sectional light absorption of approximately 90.8%, and the highest absorption efficiency is approximately 92.5%. As the degree of carbonization increases, the internal structure of the wood is less likely to absorb light (Fig. 4a).
