AbstractNonfullerene organic solar cells (OSCs) have achieved breakthrough with pushing the efficiency exceeding 17%. While this shed light on OSC commercialization, high-performance flexible OSCs should be pursued through solution manufacturing. Herein, we report a solution-processed flexible OSC based on a transparent conducting PEDOT:PSS anode doped with trifluoromethanesulfonic acid (CF3SO3H). Through a low-concentration and low-temperature CF3SO3H doping, the conducting polymer anodes exhibited a main sheet resistance of 35 Ω sq−1 (minimum value: 32 Ω sq−1), a raised work function (≈ 5.0 eV), a superior wettability, and a high electrical stability. The high work function minimized the energy level mismatch among the anodes, hole-transporting layers and electron-donors of the active layers, thereby leading to an enhanced carrier extraction. The solution-processed flexible OSCs yielded a record-high efficiency of 16.41% (maximum value: 16.61%). Besides, the flexible OSCs afforded the 1000 cyclic bending tests at the radius of 1.5 mm and the long-time thermal treatments at 85 °C, demonstrating a high flexibility and a good thermal stability.

Two water/alcohol soluble conjugated polymers (WSCPs), based on naphthalenediimide and amino-functionalized 3,4-(propylenedioxy)thiophene were synthesized via direct arylation polycondensation (DArP). The polymers worked well as electron transporting layers (ETLs) for fullerene-based...

Different Types

This paper investigates the performance of organic solar cells by using different types of metal contact. The metal contacts that have been chosen are Ag, Au and Pt. The different work function of the metals will influence the efficiency of the organic solar cells. From the results it can be seen that the absorbance value is quite high around 0.5 which absorb more photon when it is illuminated. The efficiency of the device using Pt shows the highest efficiency which is 10.62x10-3% followed by Au with 8.01x10-4% and Ag 1.25x10-4%.
