Description

[Technical field]

[0001] This invention relates to a thin-film solar cell device installed in a multipurpose heat-retaining pipe house. [Background technology]

[0002] The New Energy and Industrial Technology Development Organization (NEDO) is supporting the development of larger solar cells and sealing technology from 2021 to 2025 as part of the government's Green Innovation Fund project. Sekisui Chemical, Toshiba, Kaneka and others are advancing research and development. The Agency for Natural Resources and Energy is promoting the development and popularization of perovskite solar cells, which will help reduce carbon dioxide (CO 2 It is estimated that this will reduce the amount of emissions from solar panels by approximately 600,000 tons in 2030 and 100 million tons in 2050. The market for silicon-type solar cells has been taken over by cost-competitive Chinese companies. Chinese companies are also moving forward with mass production of perovskite-type solar cells. In May 2024, a council of around 150 organizations, including domestic manufacturers such as Sekisui Chemical, the Ministry of Economy, Trade and Industry, and the Tokyo Metropolitan Government, will be launched to promote the spread of thin, flexible "perovskite-type solar cells." A target for the amount of solar panels to be introduced will reportedly be set in order to be reflected in the next Basic Energy Plan, which will determine the electricity mix for fiscal 2040. The United Nations calls this the "boiling era," and says that unstable plant cultivation or breeding is difficult due to climate change or bad weather. Therefore, expectations are high for a multipurpose, heat-retaining pipe house thin-film solar cell device that promotes the cultivation or breeding of multiple plants in a heat-retaining pipe house equipped with perovskite-type thin-film solar cells or tandem-type thin-film solar cells, and that is characterized by its preservation.

[Summary of the Invention] [Problems to be Solved by the Invention]

[0005] Conventionally, the heat insulation of a pipe house with vinyl was configured by providing multiple layers of vinyl. Therefore, a pipe house with a heat insulation structure provided with foamed resin was invented (Utility Model Registration No. 2521638) or patented (Patent Documents 1 to 7). The solar cells provided in the pipe house with the heat insulation structure were crystalline silicon or amorphous (non-crystalline) silicon. The crystalline silicon solar cell panel (Patent Document 2, Japanese Patent Laid-Open No. 2002-272282) had problems with weight and bending. The amorphous silicon thin-film solar cell had problems with the electromotive force of about 8 to 10% conversion efficiency. To promote stable plant cultivation or breeding in a heat-insulated pipe house due to climate change or abnormal weather, which is called the boiling era of the United Nations, a lightweight or bendable thin-film solar cell was developed for a heat-insulated pipe house with a storage facility, and the problem of electromotive force was solved. In recent years, thin and bendable perovskite thin-film solar cells are said to be lightweight, inexpensive, and have high conversion efficiency, but the problem is that their durability is as short as 1 to 2 years. Therefore, Sekisui Chemical announced in 2022 that it "achieved durability equivalent to 10 years outdoors and has a prospect for mass production." By applying technologies such as sealing materials for liquid crystals, it was devised so that liquids and gases do not enter inside, achieving durability of about 10 years and a conversion efficiency of 15%. Also, it is planned to sell a 1-meter-wide perovskite thin-film solar cell in the second half of 2025. Toshiba developed a film-forming method for uniformly coating materials in 2021 and achieved a conversion efficiency of 15.1%. The highest conversion efficiency of the commercially available HESTA solar next-generation solar panel is displayed as 20.3%. The highest conversion efficiency of the perovskite type is said to be 26.1% in 2024. (Source) National Renewable Energy Laboratory of the United States. Using vacuum deposition for the perovskite type, fullerene C 60The conversion efficiency of a perovskite-type photoelectric conversion layer is improved, which includes an electron transport layer using a new material with an oxygen atom or the like attached, a power generation layer with an organic compound added as a material, and a hole transport layer with an organic compound added as a material to the power generation layer and the layer transporting positive charges, and is 20% or more. Sealing on a film substrate to prevent the intrusion of moisture and the like will lead to the realization of 20-year durability (research institutions working on improving conversion efficiency and durability: Nagoya University, Okayama University, University of Toronto). In addition, it is characterized in that it can be manufactured by a simple process such as a coating method, a printing method, or a vacuum evaporation method using a resin film or a flexible glass film (a research institution for trial production of glass film: Hokkaido University) as a substrate. The present invention has a configuration in which a perovskite-type thin-film solar cell or a tandem-type thin-film solar cell with an amorphous silicon thin-film layer junction is provided in a multi-purpose heat-insulating structure pipe house.

Means for Solving the Problems

The electric power generated by charging the electromotive force of the perovskite-type thin-film solar cell into a storage battery is used for temperature adjustment and humidity adjustment by the operation of LED lighting with an emission color suitable for plant cultivation or breeding in the house and air-conditioning equipment, and a thin-film solar cell device of a multi-purpose heat-insulating structure pipe house characterized by promoting the cultivation or breeding of a plurality of stable plants.

[0007] In the top cell layer of a tandem thin-film solar cell, recombination due to a heterojunction with an i-type amorphous silicon thin-film layer in a perovskite-type thin-film conversion layer is suppressed. In the bottom cell layer, a tandem-type semiconductor thin-film photoelectric conversion layer with a nip-type or np-type amorphous silicon semiconductor thin-film conversion layer junction has flexible glass films on both the front and back adhered and sealed. The tandem thin-film solar cell thus formed is installed on the roof and wall surfaces of a heat-insulated structure pipe house. The generated electricity from the tandem thin-film solar cell, which is charged into a storage battery, is used for temperature adjustment and humidity adjustment by operating an LED lighting with an appropriate emission color for plant cultivation or breeding in the house and an air conditioner, thereby promoting stable cultivation or breeding of multiple plants. This is a thin-film solar cell device for a multi-purpose heat-insulated structure pipe house with such a feature.

[0008] The electricity obtained by charging the generated electricity from a perovskite-type thin-film solar cell or a tandem thin-film solar cell installed in a heat-insulated structure pipe house into a storage battery is used for temperature adjustment and humidity adjustment by operating an LED lighting with an appropriate emission color and an air conditioner, thereby promoting multiple cultivation or breeding of plants in a greenhouse, low-temperature greenhouse, or constant-temperature greenhouse. This is a thin-film solar cell device for a multi-purpose heat-insulated structure pipe house with such a feature of storage.

A CdTe thin-film solar cell with high conversion efficiency is desirable as a tandem thin-film solar cell, but it contains toxicity. In Japan, it is not currently used due to the toxicity of "itai-itai disease" that occurred in the Jinzu River basin of Toyama Prefecture.
