Deskripsi
Hybrid organic-inorganic perovskites are emerging materials for efficient photovoltaics; however understanding how charge/heat dissipates inside the material remains a challenge. Here, the authors use a spectroscopic approach to observe unusually slow thermal equilibration between the organic and inorganic components.
