Conjugated Polymer Donors for Organic Solar Cells

Nickel(II) Nitrate Hole‐Transporting Layers for Single‐Junction Bulk Heterojunction Organic Solar Cells with a Record 19.02 % Efficiency

“…Owing to their unique features of light-weight, tunable optical properties, mechanical flexibility, semitransparency and ease of fabrication for large-area devices, organic solar cells (OSCs) possess great potential for versatile applications, such as being integrated into smart windows, wearable and portable electronics, etc. [1] Thanking to the great efforts devoted to the photoactive blend layers, including development of new photovoltaic materials and morphology control strategies, [2] OSCs have witnessed rapid progress in recent years. The state-of-the-art OSCs have realized impressive power conversion efficiencies (PCEs) exceeding 19 %, [2b, 3] showing their bright future for practical applications.…”

Organic–inorganic hybrid cathode interlayer materials for efficient organic solar cells

“…1 Owing to the advantages such as light weight, exibility and semi-transparency, OSCs have great application prospects in wearable equipment, colorful windows and internet of things. [2][3][4] Beneted from the extended absorption range of photoactive layers, including both polymer donors and non-fullerene acceptors, and energy loss mitigation of corresponding OSC devices, [5][6][7][8][9][10][11] power conversion efficiencies (PCEs) of single junction OSCs have exceeded 19% to date. [12][13][14][15] With respect to charge generation and transport, interfacial layers between the photoactive layers and electrodes are generally necessary.…”
