Photostability of 2D Organic-Inorganic Hybrid Perovskites
We analyze the behavior of a series of newly synthesized (R-NH₃)₂PbX₄ perovskites and, in particular, discuss the possible reasons which cause their degradation under UV illumination. Experimental results show that the degradation process depends a lot on their molecular components: not only the inorganic part, but also the chemical structure of the organic moieties play an important role in bl...
متن کاملHybrid Organic-Inorganic Perovskites on the Move.
Hybrid organic-inorganic perovskites (HOIPs) are crystals with the structural formula ABX3, where A, B, and X are organic and inorganic ions, respectively. While known for several decades, HOIPs have only in recent years emerged as extremely promising semiconducting materials for solar energy applications. In particular, power-conversion efficiencies of HOIP-based solar cells have improved at a...
متن کاملGiant photostriction in organic-inorganic lead halide perovskites.
Among the many materials investigated for next-generation photovoltaic cells, organic-inorganic lead halide perovskites have demonstrated great potential thanks to their high power conversion efficiency and solution processability. Within a short period of about 5 years, the efficiency of solar cells based on these materials has increased dramatically from 3.8 to over 20%. Despite the tremendou...
متن کاملAn extended Tolerance Factor approach for organic-inorganic perovskites.
Goldschmidt's concept of ionic Tolerance Factors was recently shown to be a valuable guideline for the preparation of new compounds within the field of organic-inorganic perovskites. Here, we extend this approach and calculate Tolerance Factors for over 2500 amine-metal-anion permutations of the periodic table. The results suggest the potential existence of more than 600 undiscovered hybrid per...
متن کاملAre Mobilities in Hybrid Organic-Inorganic Halide Perovskites Actually "High"?
The outstanding performance of hybrid organic-inorganic perovskites (HOIPs) in photovoltaic devices is made possible by, among other things, outstanding semiconducting properties: long real charge-carrier diffusion lengths, L, of up to 5 and possibly even 10 μm, as well as a lifetime, τ of ~1 μs or more in single crystal and polycrystalline films. 1–9 Top electronic transport materials will hav...
