In ternary organic solar cells (TOSCs), three different components are mixed to form the
photoactive layer, opening up opportunities to boost the power conversion efficiency—for …

Organic solar cells are composed of electron donating and accepting organic
semiconductors. Whilst a significant palette of donors has been developed over three …

The exciton, an excited electron–hole pair bound by Coulomb attraction, plays a key role in
photophysics of organic molecules and drives practically important phenomena such as …

Bulk-heterojunction organic photovoltaic devices with nonfullerene acceptors (NFAs) exhibit
efficient hole transfer with small interfacial energy offset, which results in power conversion …

All-polymer solar cells (all-PSCs) consisting of polymer donors (P Ds) and polymer
acceptors (P As) have drawn tremendous research interest in recent years. It is due to not …

The power conversion efficiencies (PCEs) of single‐junction organic solar cells (OSC) have
now reached over 18%. This rapid recent progress can be attributed to the development of …

Organic solar cells are currently experiencing a second golden age thanks to the
