Embodiment 1

[0047] Using yellow carbon quantum dots as fluorescent materials to prepare solar cells with single-sided integrated solar concentrators:

[0048] 1) Cleaning of the fluorine-doped tin oxide FTO glass substrate: use glass cleaning solution, deionized water, and isopropanol to ultrasonically clean the FTO glass substrate for 30 min in sequence. Then the glass substrate was taken out, rinsed with isopropanol, blown dry with a nitrogen gun, and finally placed in a plasma cleaner and cleaned with air for 3 minutes.

[0049] 2) Preparation of the electron transport layer: the SnO 2The colloidal solution was dissolved in deionized water (volume ratio 1:5) to form a solution, and stirred for 30 minutes. After filtering with a 0.22μm polytetrafluoroethylene filter head, spin coating for 30 seconds, 4000rpm speed, and 2000rpm / s acceleration on the cleaned FTO glass substrate, then placed on a heating table, and annealed at 150°C for 30 minutes , naturally cooled to room temperature. ...

Embodiment 2

[0057] Using green carbon quantum dots as fluorescent materials to prepare solar cells with single-sided integrated solar concentrators:

[0058] The preparation method of the perovskite solar cell device is the same as the preparation process of the solar cell device in Example 1. The specific process for the preparation of green light carbon quantum dots is:

[0059] 1) Add 30mg of m-phenylenediamine and 10mg of lignin (dealkalization) into 10mL of ethanol, and stir magnetically at room temperature until the raw materials are relatively evenly mixed. Then, the above solution was transferred to a 50mL polytetrafluoroethylene-lined stainless steel autoclave, after a high temperature and high pressure reaction at 200°C for 10 hours, it was cooled to room temperature, and the solution after the reaction was taken out to obtain the green light carbon quantum dot stock solution. Finally, the carbon quantum dot stock solution was centrifuged at 10,000 rpm for 10 minutes to remove ...

Embodiment 3

[0065] Using yellow light carbon quantum dots as fluorescent materials, solar concentrators were prepared by spin coating:

[0066] The specific process for the preparation of yellow light carbon quantum dots is:

[0067] 1) Add 30 mg of o-phenylenediamine and 10 mg of lignin (dealkalization) into 10 mL of ethanol, and stir magnetically at room temperature until the raw materials are relatively evenly mixed. Then, the above solution was transferred to a 50mL polytetrafluoroethylene-lined stainless steel autoclave, cooled to room temperature after a high-temperature and high-pressure reaction at 200°C for 10 hours, and the reaction-completed solution was taken out to obtain a yellow light carbon quantum dot stock solution. Finally, the carbon quantum dot stock solution was centrifuged at 10,000 rpm for 10 minutes to remove large particles of precipitated impurities, and then the supernatant was mixed with an equal volume of ethanol for dilution, and the diluted supernatant was ...

Abstract

The invention belongs to the technical field of solar cell and solar light collector materials, and particularly relates to a solar cell integrated with a solar light collector and a preparation method of the solar cell. The solar cell integrated with the solar light collector comprises a substrate and a solar cell device arranged on a conductive surface of the substrate, the solar cell device is provided with a metal electrode layer, and a light-collecting fluorescent material layer is arranged on one surface, opposite to the solar cell device, of the substrate; and / or an up-conversion fluorescent material layer is arranged on one surface, back to the solar cell device, of the metal electrode layer. Through the arrangement of the light-collecting fluorescent material layer and / or the up-conversion fluorescent material layer, the solar energy utilization rate of the device can be effectively improved, and the application prospect of the device is widened.

Description

technical field [0001] The invention belongs to the field of solar cell and solar concentrator material and technology, and in particular relates to a solar cell integrated with a solar concentrator and a preparation method thereof. Background technique [0002] Since 2012, perovskite solar cells have stimulated the research interest of a large number of scholars. Perovskite semiconductor materials have many excellent properties, such as direct bandgap semiconductor, high light absorption coefficient, excellent carrier transport rate and so on. The photoelectric conversion efficiency of its single cell has increased from 3.8% reported for the first time in 2009 to the current 25.5%, and the photoelectric conversion efficiency of stacked cells combined with crystalline silicon solar cells has reached 29.5%. Such rapid development makes perovskite solar cells a strong contender for a new generation of commercial thin-film cells. The device composition of perovskite solar cel...
