The status and breakthrough of agricultural photovoltaic
Environmental pollution and pollution haze are increasingly attracting the attention of government institutions.The Chinese government has made a commitment to the world: to vigorously develop non-fossil energies,of which solar energy is one of the most important clean energy.Because centralized photovoltaic power stations require large areas of land,most power stations are in the sparsely populated western region.But precisely because of that sparse population,solar power cannot be used locally where it is needed.Therefore,under the aspect of developing clean energy,the government has advised and encouraged the establishment of distributed photovoltaic power stations in densely populated eastern regions.However,in these densely populated areas,the per capita cultivated land is very limited.Under this background,new industries of photovoltaic agriculture have emerged.The construction of photovoltaic agricultural projects is not only happening in China,but also in Japan,Italy,Germany,and some other majorly important countries.However,problems which have seriously affected the growth of plants with traditional photovoltaic agriculture projects have become increasingly obvious.The traditional photovoltaic agriculture projects mainly adopt the following two methods: to place raised above the farm field polycrystalline silicon solar panels to achieve geometrical separation of sunlight or using amorphous silicon solar cells with inherent spectral characteristics to separate the sunlight.Neither of these two photovoltaic agriculture solutions match the spectrum requirement for photosynthesis of plants and this has gravely affected the quality and yield of crops.Thus,in China alone,the industrial scale of photovoltaic agriculture fell from a volume of 10 billion Yuan in 2015 to less than 1 billion Yuan in 2017.The solar spectrum separation technology of the team of Professor Liu Wen of University of Science and Technology of China accommodating an effective plant photosynthesis has solved the contradiction between simultaneous photovoltaic power generation and plant growth.The results show that this system scheme truly achieves the balance between plant growth and photovoltaic power generation.It can realize the efficient use of solar energy and land,save water resources,and improve the ecological environment.The introduction and promotion of this program may have far-reaching implications for agriculture,new energy and natural ecology in the future.
