Single‐Junction Organic Photovoltaic Cells with Approaching 18% Efficiency

Abstract Optimizing the molecular structures of organic photovoltaic (OPV) materials is one of the most effective methods to boost power conversion efficiencies (PCEs). For an e...

Over 16% efficiency organic photovoltaic cells enabled by a chlorinated acceptor with increased open-circuit voltages

Broadening the optical absorption of organic photovoltaic (OPV) materials by enhancing the intramolecular push-pull effect is a general and effective method to improve the power...

Single‐Junction Organic Photovoltaic Cell with 19% Efficiency

Abstract Improving power conversion efficiency (PCE) is important for broadening the applications of organic photovoltaic (OPV) cells. Here, a maximum PCE of 19.0% (certified va...

Over 14% Efficiency in Polymer Solar Cells Enabled by a Chlorinated Polymer Donor

Abstract Fluorine‐contained polymers, which have been widely used in highly efficient polymer solar cells (PSCs), are rather costly due to their complicated synthesis and low yi...

An Organic D-π-A Dye for Record Efficiency Solid-State Sensitized Heterojunction Solar Cells
