Problems solved by technology

[0003] At present, commercial solar cells (such as silicon cells) show very high photoelectric conversion efficiency outdoors, but when used under indoor light conditions, the photoelectric conversion efficiency is very low (Energies 2014, 7, 1500-1516; Appl .Energy, 2017, 191, 10-21)

Embodiment 1

[0108] Example 1 Preparation of IO-4Cl Compound

[0109] Refer figure 2 The synthetic route, 199.1 mg of Compound 1 (purchased from Suli Organic Optoelectronics Technology (Beijing) Co., Ltd.) and 214.8mg Compound 2 (purchased from Suli Organic Optoelectronics Technology (Beijing) Co., Ltd.) added to 50ml round bottom flask. The air in the bottle is introduced into the bottle to carry out argon protection. A 20 mL of chloroform and 0.2 ml of pyridine were added. Then, the round bottom flask was moved into a 65 ° C oil bath to stir for 15 hours. After the reaction was completed, 208.6 mg of Compound IO-4Cl was purified by column.

Embodiment 2

[0113] Example 2 A photovolus battery is prepared based on a PBDB-TF / ITCC system

[0114] PBDB-TF (from SOLAMERMETERIALINC Purchase) with ITCC (purchased from SOLAMERMETERIALIALINC) with a weight ratio of 1: 1 common mixed dissolved in chlorobenzene to prepare 10 mg / ml of blended activatable layer solution, then 0.5% by volume 1, 8 - iodine octane is prepared in the blended spiral solution. Device preparation is followed by: First, the commonly used anode modification layer PEDOT: PSS is spin coated on the surface of ITO, annealing at 150 ° C for 20 minutes. The substrate was then moved to the glove box, and the above blended activated layer solution was then copies into a membrane (2000 rmp / min, 90s) on the PEDOT: PSS layer. The film was then annealed at 100 ° C for 10 minutes. After the substrate is cooled, ZnO nanoparticles (dispersed in methanol solution) are spin on the active layer film. Finally, at approximately 10 -4 A 100 nm aluminum layer was evaporated under press...

Abstract

The invention discloses a non-fullerene organic photovoltaic cell and its application. The non-fullerene organic photovoltaic cell includes an active layer containing an acceptor material and a donor material, and the acceptor and the donor are non-fullerene materials; the application is that the non-fullerene organic photovoltaic cell is used in indoor light down-drive microelectronics. The present invention uses non-fullerene materials as the active layer of the battery, and the organic photovoltaic cell obtained by the non-fullerene donor and acceptor structure. Compared with the solar cells generally commercially produced in the market, it can realize 18 % of photoelectric conversion efficiency.

Description

Technical field [0001] The present invention belongs to the field of organic photovoltaic cell applications, and more particularly to the application of non-Fillene organic photovoltaic cells under indoor light and non-Villene photoelectric material. Background technique [0002] With the arrival of the Internet of Things, all types of distributed microelectronic products are widely used. Such products are concentrated in indoor environments, with micro-power, high dispersion distribution, small size. The photovoltaic cell can capture indoor light to provide continuous, off-grid energy sources for such products. Compared with sunlight, the emission spectrum and light strength of artificial lighting are very different. The emission spectrum of the LED (LED) and the fluorescent lamp is mainly concentrated between 400-700 nm, while the sun spectrum is typical black body radiation, and its emission spectra is very wide; in addition, the light of the indoor light is generally less tha...
