Organic solar cells (OSCs) are promising renewable energy sources for replacing fossil fuels. The power conversion efficiency (PCE) of OSCs has increased based on tremendous effort in material and device engineering. Still, the stability of OSC, such as long lifetime, negative temperature coefficient, must be enhanced for commercialization. In this...

... A buffer layer of poly (3,4-ethylenedioxythiophene): poly(styrenesulfonate) (PEDOT: PSS) and an active layer of PM6Y6 in a 1:1.2 weight ratio were employed. The refractive indices of glass, aluminum, PEDOT:PSS, ITO, and PM6Y6 were obtained from the literature 37,38 . In order to estimate the transmittance (T) and reflectance (R) spectra, two FDTD power monitors are utilized as shown in Fig. 1b. ...
