Versatile organic photovoltaics with a power density of nearly 40 W g⁻¹

This is the authors' abstract. We don't add key points for this paper.

Ultra-thin OPVs with record efficiency, the highest power density and tunable colors are demonstrated. The OPVs was fabricated on a 1.3 micro-meter substrate, and demonstrated a record efficiency of 17.32% and an excellent power density of 39.72 W g −1 .
