Abstract
Semitransparent organic solar cells have become attractive recently because of their photon harvesting in the near-infrared and ultraviolet range and passing in the visible light region. Semitransparent organic solar cells with Glass/MoO3/Ag/MoO3/PBDB-T:ITIC/TiO2/Ag/PML/1DPCs structure have been studied in this work and the effects microcavity with 1-dimensional photonic crystals (1DPCs) on the solar cell performance such as the power conversion efficiency, the average visible transmittance, Light utilization efficiency (LUE), the color coordinates in the CIE color space, and CIE LAB are investigated. The analytical calculation including the density of exactions and their displacement is used to model the devices. The model shows that the presence of microcavity can improve the power conversion efficiency by about %17 in comparison with the absence of microcavity. Although the transmission is decreasing slightly, microcavity does not change the color coordinates much. The device can transmit high-quality light with a near-white sensation to the human eye.
