Abstract

Building integrated semitransparent thin‐film solar cells is a strategy for future eco‐friendly power generation. Organic photovoltaics in combination with dielectric mirrors (DMs) are a potential candidate as they promise high efficiencies in parallel to the possibility to adjust the color and thus the transparency of the whole device. A fully solution processed and printable DM with an easily adjustable reflection maximum is presented that can be facilely attached to solar cells. The DM is optimized via optical simulations to the particular needs of the device with regard to photocurrent enhancement. The excellent agreement between experimental and theoretical results confirms the high optical quality of the printed layers with respect to homogeneity and surface roughness. The used inks are organic–inorganic nanocomposites with a large refractive index contrast of ≈0.7. The short‐circuit current is enhanced by up to ≈24% for a semitransparent polymer solar cell.
