The front cover illustrates polymer solar cells fabricated using the processing additive (PA) technique and a TiO x optical spacer. While the polymer solar cell without the PA technique has rough surface morphology, resulting in a diffused reflection, the polymer solar cells with the PA technique show smooth surface morphology and thereby exhibit constructive interference of the reflected light. The synergistic effect of the PA technique and the optical spacer leads to increased power conversion efficiency and device lifetime, as reported by Kwanghee Lee, Guillermo C. Bazan, and co‐workers on page 1420 .
