Problems solved by technology

The currently reported nanoparticle additives are only SiO 2 Nanoparticles, SiO 2 Nanoparticles provide channels for anion transport and form a network scaffold material, but at the same time SiO 2 Nanoparticles tend to agglomerate, thus affecting the long-term stability of solar cells
[0006] So far it has not been known how adding nanoparticles to the electrolyte of nanocrystalline solar cells affects the performance of the electrolyte and the performance of the solar cell
Our research shows that when adding non-surface modified nanoparticles to the electrolyte, the nanoparticles are easily precipitated, causing phase separation problems and affecting the stability of solar cells

Embodiment 1

[0046] Embodiment 1: Synthesis of 3-methyl-1 phenyl-4-(octadecanoyl)pyrazolone-5 (PMOP)

[0047] Add 7.0g (0.04mol) of 1-phenyl-3-methyl-pyrazolone-5 and 100ml of anhydrous 1,4-dioxane into a dry three-necked flask, heat and stir until dissolved, and add 9g of hydrogen The powder of calcium oxide and 1 g of barium hydroxide was cooled to room temperature, 15 ml (0.04 mol) of octadecanoyl chloride was added dropwise, and the mixture was stirred and refluxed for 2 hours. The reaction mixture was poured into 300ml of 0.5mol / L dilute hydrochloric acid, filtered with suction, and recrystallized twice with ethanol-water mixed solvent to obtain light pink needle-like crystals. Yield 65%. 1 H-NMR (400Hz, CDCl 3 )(δppm): 7.26-7.84 (5H, m, ArH), 2.73 (2H, t, CH 2 ), 2.48 (3H, s, CH 3 ), 1.74 (2H, m, CH 2 ), 1.24-1.43 (28H, m, (CH 2 ) 14 ), 0.88 (3H, t, CH 3 ). Its H 1 The nuclear magnetic resonance spectrum is shown in Figure 2.

Embodiment 2

[0048] Example 2: Synthesis of 3-methyl-1-phenyl-4-decanoylpyrazolone-5 (PMDP)

[0049] Add 0.01mol) 1-phenyl-3-methyl-pyrazolone-5 and 100ml anhydrous 1,4-dioxane in a dry there-necked flask, heat and stir until dissolved, add 9g calcium hydroxide and 1 g of barium hydroxide powder was cooled to room temperature, and 0.01 mol) of decanoyl chloride was added dropwise, and stirred and refluxed for 2 hours. The reaction mixture was poured into 100ml of 0.5mol / L dilute hydrochloric acid, filtered with suction, and recrystallized twice with ethanol-water mixed solvent to obtain white needle-like crystals. Yield 72%. 1 H-NMR (400Hz, CDCl 3 )(δppm): 7.29-7.85 (5H, m, ArH), 2.74 (2H, t, CHH 2 , 2.48 (3H, s, CH 3 ), 1.76 (2H, m, CH 2 ), 1.26-1.44 (12H, m, (CH 2 )6), 0.88 (3H, t, CH 3 ).

Embodiment 3

[0050] Embodiment 3: the synthesis of 3-methyl-4-octadecanoyl oxazolinone (OxOP)

[0051] Following the same method as in Example 1, but replacing 1-phenyl-3-methyl-pyrazolinone-5 with 3-methylazolinone-5, to prepare 3-methyl-4-octadecane Acyloxazolones (OxOP). The crude product of this product can be purified by recrystallization from ethanol. The melting point is 78-80°C.

Abstract

In this invention a nanometer crystal solar energy battery and its producing method are illustrated. On the wide band semiconductor nanometer crystal film, the organic ligand beta-diketone covered nanometer particle is settled on, which substitutes the liquid electrolyte to solve the sealing problem. Without reducing the effect of the photovoltaic conversion of the battery, the working life of the solar energy battery is greatly prolonged.

Description

technical field [0001] The invention belongs to the technical field of nanometer materials, and in particular relates to a quasi-solid-state nanocrystalline solar cell using beta-diketone ligand-wrapped nanoparticle as a scaffold material and a preparation method thereof. Background technique [0002] With the continuous growth of the world population, human beings are faced with two major problems of food and energy. The development of new clean energy has become an important topic. [0003] According to statistics, the annual solar radiation reaching the ground is 3×10 24 J (equivalent to 1.3 million tons of standard coal), if a solar cell with a conversion efficiency of 10% covers 1 / 1000 of the global surface, it can meet the energy needs of all mankind. Therefore, converting solar energy into electrical energy has become one of the important research fields in recent years. At present, as one of the types of solar cells, a new type of thin-film solar cell, especially ...
