Organic photovoltaics (OPVs) have progressed steadily through three stages of photoactive
materials development:(i) use of poly (3-hexylthiophene) and fullerene-based acceptors …

A deep understanding of defects is essential for the optimization of materials for solar energy
conversion. This is particularly true for metal oxide photo (electro) catalysts, which typically …

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

The bulk-heterojunction blend of an electron donor and an electron acceptor material is the
key component in a solution-processed organic photovoltaic device. In the past decades, a p …

Organic solar cells (OSCs) have been dominated by donor: acceptor blends based on
fullerene acceptors for over two decades. This situation has changed recently, with non …

The open-circuit voltage of organic solar cells is usually lower than the values achieved in
inorganic or perovskite photovoltaic devices with comparable bandgaps. Energy losses …

In organic solar cells, the charge-transfer (CT) electronic states that form at the interface
between the electron-donor (D) and electron-acceptor (A) materials have a crucial role in …

The field of organic photovoltaics has developed rapidly over the last 2 decades, and small
solar cells with power conversion efficiencies of 13% have been demonstrated. Light …

Over the last 5 years, research on the synthesis, device engineering, and device physics of
solution‐processed small molecule solar cells (SMSCs) has rapidly expanded …

Despite numerous organic semiconducting materials synthesized for organic photovoltaics
in the past decade, fullerenes are widely used as electron acceptors in highly efficient bulk …
