Abstract: Abstract The poor optical transmittance of common electrodes based on thin metal films in three-terminal parallel tandem solar cells poses a major hindrance to attaining high power conversion efficiency (PCE). High optical transmittance and electrical conductivity of the common electrodes are crucial to achieving high PCE. We report a parallel polymer tandem solar cell that contains a comb-shaped electrode (CSE) based on gold (Au), which provides both high optical transmittance and low electrical resistance. We studied the performance of the ta...
