A Yolk@Shell Photothermal Structure for Integrated Solar‐Driven Undrinkable Water Purification and Thermoelectric Power Generation

open access: yesAdvanced Science, Volume 13, Issue 18, 27 March 2026.
A yolk@shell structured photothermal evaporator was prepared via simple sol‐gel and spray coating methods. By taking advantage of the unique yolk@shell structure, the position of the TE module within the evaporator can be optimized without affects its water evaporation performance. This results in efficient and stable evaporation (3.08‐3.17 kg m−2 h−1)‐
