Geometry design of tethered small-molecule acceptor enables highly stable and efficient polymer solar cells

The variation on molecular topology and aggregation behaviour of tethered small molecule acceptors is critical to device operating performance. Here, the authors designed two isomeric dimers via the thiophene-core engineering and realize device efficiency of 18.1% and long stability in solar cells.

Low-cost synthesis of small molecule acceptors makes polymer solar cells commercially viable

The high−cost of the acceptor-donor-acceptor structured small molecule acceptors impedes its commercial viability for polymer solar cells. To address this problem, here, the authors developed a simple and cheap boron trifluoride etherate-catalyzed Knoevenagel condensation with high reaction efficiency.

Cathode engineering with perylene-diimide interlayer enabling over 17% efficiency single-junction organic solar cells

It is desired to design cathode interfacial layers to simultaneously improve the efficiency and stability of organic solar cells and tune the cathode properties. Here, Yao et al. develop such interfacial layers for the best donor-acceptor system and achieve a high certified efficiency close to 17%.

11.4% Efficiency non-fullerene polymer solar cells with trialkylsilyl substituted 2D-conjugated polymer as donor

In organic photovoltaics, non-fullerene acceptors relax matching rules and allow for the development of new donor polymers. Here, Bin et al. design a donor polymer and obtain high photoconversion efficiencies despite the low energy offset for hole transfer between the acceptor and the donor.

Ultrafast hole transfer mediated by polaron pairs in all-polymer photovoltaic blends

All-polymer solar cells have shown high efficiencies but the ultrafast charge transfer processes are less known. Here Wang et al. show that polaron pairs play vital role facilitating the hole transfer, which is quite different from the exciton dominated pathway in polymer-fullerene blends.

A low cost and high performance polymer donor material for polymer solar cells

A problem that hinders the commercialization of polymer solar cells is the complication in synthesis and thus the low yield and high cost of the polymers. Here, Sun et al. synthesize a new polymer via a two-step process with a yield close to 90% and show high photovoltaic performance with efficiency of 12%.

Simplified synthetic routes for low cost and high photovoltaic performance n-type organic semiconductor acceptors

Non-fullerene organic molecule acceptors have been the hot research subject to drive the efficiency of the organic solar cells higher, but their synthetic costs are high. Here Li et al. design a simplified synthetic route for the state-of-the-art acceptors and bring down their cost by more than 15%.
