Germanium(II) Iodide (CAS 13573-08-5) Applications

Germanium(II) Iodide (CAS 13573-08-5) has applications in the photovoltaic field as shown below. 

We further fabricated solar cells with the germanium iodide perovskites using compact and mesoporous TiO2 and SpiroOMeTAD as electron- and hole-selective contacts, respectively. Our devices exhibit a photocurrent density of 5.7 mA cm2 and 4 mA cm2 for CsGeI3 and MAGeI3 compounds, respectively, as shown in Fig. 4(a). These values are encouragingly higher than that derived from the pristine Sn-based perovskite compounds. Computational screening has suggested that germanium may act as a suitable replacement for lead in halide perovskite materials for solar cell applications.

Overall, the results of the present study demonstrate the strong potential of Ge-based halide perovskite compounds in photovoltaic applications.[1]
