Hole transport layers(HTLs)play a vital role in organic solar cells(OSCs).In this work,a derivative of tetrathiafulvalene with four carboxyl groups TTA was intr
Understanding of the oxygen reduction reaction(ORR)mechanism for single atom catalysts is pivotal for the rational design of non-precious metal cathode material
Lithium–sulfur (Li–S) batteries are great candidates for energy storage systems, but need to overcome theissues of low sulfur utilization and polysulfide shut
