Highly efficient solar-absorber composite material based on tetrapyridylporphyrin for water evaporation and thermoelectric power generation

Photothermal conversion materials based on tetrapyridylporphyrin (TPyP) were studied and were found to possess a polypyrrole macrocyclic framework (18π electrons), which makes them exhibit strong absorption in the 300–800 nm region and high photothermal conversion.
