preparation example Construction

[0102] Except for the preparation of PEDOT:PSS films, all the preparation processes were carried out in a glove box or vacuum provided with nitrogen inert atmosphere. In order to make the above-mentioned vacuum thermal evaporation metal thin film process, the growth sedimentation rate and the total deposition thickness of the film are controlled by the applied thermal power, and are monitored in real time by a quartz crystal film thickness monitor (STM-100 type, manufactured by Sycon Corporation). The ultraviolet-visible light absorption spectrum of the active layer or the polymer electron donor material is measured by a HP8453A diode array ultraviolet-visible spectrophotometer, and the wavelength range of the test is 190 nanometers to 1100 nanometers.

[0103] The measurement process of the photoluminescence spectrum of the polymer electron donor material is as follows: according to the test results of its absorption spectrum, an appropriate excitation source is selected. The...

Embodiment 1

[0107] Using poly[3,4,5-trimethoxy-1-[(3-amino-4-nitrophenyl)thio]benzene] as the electron transport layer, PFO-DBT35 as the electron donor material, PCBM as the electron acceptor material. Compared with the conventional device without electron transport layer, the open circuit voltage is greatly increased from 0.60-0.65 volts to 0.90-0.95 volts.

Embodiment 2

[0109] Using poly[3,4,5-trimethoxy-1-[(3-acetamido-4-nitrophenyl)thio]benzene] as the electron transport layer, PFO-DBT15 as the electron donor material, PCBM as the electron acceptor material. Compared with the conventional device without electron transport layer, its open circuit voltage is greatly increased from 0.60-0.65 volts to 0.85 volts.

Abstract

The invention discloses a solar cell comprising an electronic transmission layer and a hole transmission layer. The solar cell comprises a substrate, an anode, the hole transmission layer, an active layer and a cathode which are stacked in sequence, wherein the hole transmission layer is PEDOT:PSS. The electronic transmission layer is arranged between the active layer and the cathode and made of a polymer with a monomer represented by structural formula (I), and the n is an arbitrary integer ranging from 1 to 300. A in the formula (I) is selected from 4-nitro substituted phenyl represented by structural formula (II), 4-alkoxy substituted phenyl represented by structural formula (III), substituted heterocycle represented by structural formula (IV), or substituted heterocycle represented by structural formula (V). The solar cell has high open-circuit voltage and good device performance.

Description

technical field [0001] The invention relates to the field of photoelectric devices, in particular to a solar cell. Background technique [0002] With the increase of global energy demand year by year and the depletion of primary energy sources such as oil and coal, people are paying more attention and research to renewable resources such as wind energy and solar energy. Among them, solar cells based on photovoltaic effect are one of the hot spots. one. [0003] At present, mature solar cells on the market are mainly inorganic solar cells based on monocrystalline silicon, polycrystalline silicon, amorphous silicon, gallium arsenide, indium phosphide, and polycrystalline compound semiconductors. Among them, polycrystalline silicon and amorphous silicon solar cells are used in civilian applications. Dominant in the solar cell market. After more than 50 years of development, the photoelectric conversion efficiency of inorganic monocrystalline silicon solar cells has increased ...
