British media said that a company is currently developing a new type of combined solar power generation and storage for the UK. According to reports, the company combines thin, soft and light solar panels with energy storage materials to power buildings or charge off-grid vehicles. The report said that Solivus, which developed the device, plans to cover the roof of large industrial buildings with solar materials. These buildings include supermarket warehouses and courier company distribution centers. However, Solivus also plans to manufacture solar installations or "curves" for home use. The goal is to create local renewable energy, allow residents and businesses to have their own electricity supply, and help the UK achieve its goal of zero net greenhouse gas emissions by 2050. This solar material is a carbon-based film, which the company calls "organic photovoltaics." It is a material that absorbs sunlight and produces energy. The company said the film is only one-tenth the weight of traditional films, does not contain rare earth or toxic materials, and has a lifespan of up to 20 years. The company said that its efficiency in the laboratory is about 13%, but as the temperature continues to rise under natural light, its efficiency remains stable. The inventor of this combined power generation and storage device is Joe Parker-Swift with a background in biological sciences. She has established, developed, and sold two companies. Solivius ’medium-term plan is to install thin-film devices in large commercial properties and stadiums in the United Kingdom in 2021/2022. They anticipate that a 10,000 square meter roof will provide about 1 megawatt of energy-perhaps enough to power an apartment. The company is also working with the University of Manchester Graphene Engineering Innovation Center to study whether graphene can play a role. Graphene is a powerful 2D material that is only one atom thick, and it can effectively conduct heat and electricity. The next step is more gentle-solar panels have been installed on a farm building. And this film has been shaped into an "arc", designed to absorb more light. It is expected that a unit will be a 1 kW system, which can supply 1,000 kWh per year. Researchers at the University of Surrey in the UK are evaluating the public's response to this idea and design. Professor Michael Walls of the Renewable Energy System Technology Center at Loughborough University said that the concept of using light photovoltaic cells in buildings is "exciting" because it opens up new fields of application for solar energy. But there are also economic and practical obstacles. The current scale of the flexible photovoltaic product market is much smaller than the traditional rigid solar panel market, which means that manufacturers of flexible photovoltaic products cannot achieve economies of scale like rigid solar panel manufacturers. Walls said that some flexible solar films also have problems with water penetrating into the coating and eventually causing degradation. He said: "If they can sell products at a reasonable price and avoid technical problems, it will be a great thing, but there are many challenges."
It is composed of 3 levels. The upper level and the lower level are Woven Geotextile and non woven textile. The middle level is bentonite grains, which are carefully selected from Liu Fangzi crude and filled in between the two levels after special processing.

Its waterproof properties are much more durable than that of the buildings. Sodium bentonite would transform to high density septum under hydro pressure. When The thickness is 3mm, the permeability is below a×10-11/sec(a=1~9), which equals to the density of 100 times of the clay with 30 mm thickness. Water retention performance is evident.

1. Environment friendly
GCL is made of natural raw materials of sodium-bentonite. It is raw and natural materials,;aging and corrosion seldom happen. It can keep its quality and then it does not cause any injuries and pollution for human and the environment. It is not only waterproof, but also has good ventilation performance. It can stick up for the exchange of the ecological environment. It is a pure natural, new, green waterproof material.
2. Permanent waterproof, excellent performance
Natural sodium bentonite was formed billions of years ago.
3. Easy to construct
Bentonite powder, nails and washers are enough for connection and fixation. Construction is not constrained by weather conditions and it could be taken under cold or wet conditions. Bentonite powder is spread on overlap point. When water comes, GCL would be overlapped automatically. It is so far the only material that starts the waterproof effect by water in the world. It is not necessary to take additional examination when the construction is completed. The repair works are easy in case of waterproof defects. Among the existing waterproof materials, GCL`s construction period is the shortest and its operation is the easiest. It has an eminent effect on shortening the construction period as well as saving the cost.
4. Strong Self-Restore Capacity
The integration between waterproof material and its target enables GCL a 20~28 times swelling volume. Even if concrete structure trembles or subsides, the bentonite in GCL would restore the crack of 2mm or below on the concrete structure immediately. Even if the diameter of perforation reaches 30 mm, the restoration will be finished within 15 days completely.
