Astigan, headquartered in Bridgewater, UK, is developing asolar energyA drone, it has a battery life of 90 days and takes high-quality photos. It hovers 20,400 meters above the ground and sends snapshot images to organizations and businesses. The first test of the Astigan-type drone is expected by the end of this year. The Astigan drone weighs 150 kilograms and has a wingspan of 40 meters. It can carry a range of interchangeable Earth observation instruments such as high-precision cameras, atmospheric monitoring systems and multispectral sensors. In addition to military applications, it is of great significance for urban planning, land management, environmental change, and even natural disaster relief.

According to the Australian website, a shopping center in Western Australia recently adopted a world-first energy experiment project, replacing the glass at the entrance of its shopping center with completely transparent glass.solar energyPower Equipment.

According to reports, Vicinity Centres, Australia's largest retail real estate giant, has recently partnered with technology company ClearVue Technology to replace the former glass doors in the Warwick Grove shopping mall in Western Australia with 26 transparent solar panels that can generate 1 megawatt hour of electricity per year. power.

On January 25, according to a news release by Jinko, the conversion efficiency of its large-area N-type single crystal TOPCon cells reached a record 24.2%.

This test was led and completed by the Quality Inspection Center of Solar Photovoltaic Power System and Wind Power System of Chinese Academy of Sciences. Using Jinko's cell design, the output power of the N-type half-cell module (60 cells) has set a world record of 387.6W.

Across the globe, a range of companies from Oxford, England to Redwood, California are working to bring the newsolar energy" target="_blank">The commercialization of solar energy technology will further promote the application of renewable energy generation. OxfordPV is a start-up company in partnership with Oxford University. Earlier this year, it received $3 million from the UK government to use In the U.S., a company called SwiftSolar raised $7 million two days ago to put the same technology to market.

As solar cell materials, lead-based perovskites have received extensive attention. However, the inherent instability and toxicity of lead (Pb) have raised serious concerns about the viability of lead-based perovskites as solar cell materials, hindering the large-scale commercialization of solar cells and similar devices based on these materials.

Although lead-free perovskites can be used as an alternative to compensate for the toxicity of lead-based perovskites, they are less useful due to their lower efficiency.

According to a recent report by the German "Aviation Journal" website, at the end of last year, a German research team created asolar energyUAVs can stay in the atmospheric stratosphere for up to 3 months. According to the research and development progress, the solar-powered UAV will be tested soon after the relevant test work. Compared with traditional aircraft, solar-powered drones do not need to carry any fuel, and can use the electricity generated by solar cells for long-distance flight of the aircraft, and can also rely on the solar energy stored during the day to continue flying at night. Because of this, solar drones have very broad application prospects, and solar drones are just a microcosm of the development of solar cell applications by foreign troops.

Engineers at MIT have come up with a conceptual design for storing renewable energy such assolar energyand wind energy, and send energy back to the grid as needed. The new design can not only power small cities when solar and wind energy is sufficient, but also power supply day and night. The study design was published in the journal Energy and Environmental Science.

According to a report by Kyodo News on January 21, Toshiba announced on the 21st that it has successfully achieved cuprous oxide for the first time.solar energyTransparency of the battery. It is envisaged to be applied to products that can be superimposed on widely available crystalline silicon solar cells to improve power generation efficiency. Cuprous oxide, an oxide of copper, is said to reduce costs significantly because copper is cheap to purchase.

According to the report, it has been confirmed that the cuprous oxide solar cells placed above can transmit light, so that the crystalline silicon solar cells placed below can maintain high power output. It is said that by precisely controlling the amount of oxygen in the preparation of cuprous oxide thin films, transparency, which has been difficult in the past, has been achieved.

According to foreign media reports, SolarEdge announced that electric vehicle (EV) consumers can now use Google Assistant (Google Assistant) to control their electric vehicle charging.solar energyinverter. Sole Technology Co., Ltd. was one of the first companies to integrate electric vehicle charging with Google Assistant.

Sole Technology offers the world's first solar inverter for EV charging, which charges up to 6 times faster than standard Level 1 chargers through an innovative solar boost mode. Integrating this technology into Google Assistant can simplify the charging process of electric vehicles for consumers and meet the needs of smart energy solutions.

Recently, the team of Wu Kaifeng, a researcher at the Dalian Institute of Chemical Physics, Chinese Academy of Sciences, proposed the concept of "quantum tailoring solar concentrator" for the first time based on nanocrystalline materials doped with rare earth metal ytterbium, and based on this concept, a prototype device of high-efficiency solar concentrator was prepared. The research was published in Nano Letters.
Fluorescent solar concentrators have advantages
Since 2011, solar photovoltaic power generation systems have developed rapidly around the world. According to a report released by the International Energy Agency (IEA), my country ranked first in the market in terms of new and cumulative installed capacity in 2017, with the newly installed capacity of 53GW accounting for 54.08% of the world's total new installed capacity.
