(a) Shows measured and simulated external quantum efficiency (EQE)% and (b) shows measured and simulated percentages of reflectance, transmittance, and absorbance spectra of semitransparent CH₃NH₃PbI₃ solar cell with the architecture glass/ITO-front/ITO-front-roughness/SnO₂/PCBM/CH₃NH₃PbI₃/CH₃NH₃PbI₃-roughness/spiro-OMeTAD/ITO-rear/ITO-rear-roughness. The dotted line represents measurements on the actual device and solid line represents transfer-matrix-based simulations.
