A metal-organic framework converted catalyst that boosts photo-electrochemical water splitting
Royal Society of Chemistry (2019-04-08)Realization of photo-electrochemical water splitting to generate H2 alternative fuel requires the facilitation of the kinetically-sluggish oxygen evolution reaction (OER) occurring at the photoanode. To do so, there is a ... -
Interface Engineering in Perovskite Solar Cells by Low Concentration of Phenylethyl Ammonium Iodide Solution in the Antisolvent Step
Wiley (2021-12-03)In spite of the outstanding properties of metal halide perovskites, its polycrystallinenature induces a wide range of structural defects that results in charge losses thataffect thefinal device performance and stability. ... -
Interfacial Passivation of Perovskite Solar Cells by Reactive Ion Scavengers
American Chemical Society (2021-02-22)Lead halide perovskites suffer from uncontrolled ion migration and the interactions at the external contacts play a fundamental role in the hysteretic response and performance degradation kinetics. In this work, we passivate ... -
Superior Performance of V2O5 as Hole Selective Contact over other Transition Metal Oxides in Silicon Heterojunction Solar Cells
Elsevier (2017)Transition metal oxides (TMOs) have recently been proved to efficiently serve as hole-selective contacts in crystalline silicon (c-Si) heterojunction solar cells. In the present work, two TMO/c-Si heterojunctions are ... -
Suppressing Nonradiative Recombination in Lead–Tin Perovskite Solar Cells through Bulk and Surface Passivation to Reduce Open Circuit Voltage Losses
American Chemical Society (2022-10-14)Lead–Tin perovskite solar cells (Pb/Sn PSCs) are limited by the intrinsic instability of Sn(II), which tends to oxidize forming Sn vacancies in perovskite films. Herein, a Lewis base β-guanidinopropionic acid (GUA) and ...
