It is an alternative to the methyl ammonium (MA; CH3NH3+) or formamidinium (FA; CH(NH2)2+) ions commonly utilized in the perovskite solar cells, may bring additional advantages due to its triad rotational symmetry and zero dipole moment (μ). We noticed that due to steric factors, GA preferably forms two-dimensional (2D) layer, where GA2PbI4 is favored monoclinic structure (E g = 2.5 eV) and the obtained device efficiency is η = 0.45%. This study provides a guideline for designing guanidinium based perovskite absorbers for solar cell devices. In addition, through further compositional engineering with mixed organic cations using GA may enhance the device performance.||URI:||https://hdl.handle.net/10356/141483||DOI:||10.7567/JJAP.56.08MC05||Rights:||© 2017 The Japan Society of Applied Physics.
