Solar power glass realizes energy neutralization

Faced with a growing global population and increasing extreme weather conditions, future farmers may increasingly need to use greenhouses to produce viable crops. However, although the greenhouse can provide a safe and stable environment for growing products, especially in areas with severe temperature fluctuations, it requires constant manual heating and/or cooling.

Solar power glass uses energy from unused light wavelengths in photosynthesis to help turn greenhouses into self-sufficient solar power plants. Traditional opaque solar panels will be useless at this point because they will block light from entering the room.

A team has developed a computational model to accurately assess the power generation potential of solar cells in tomato greenhouses in three US states. They chose glass-like organic solar cells because of their light weight, low cost, and translucent structure, providing a large surface area for energy production.

The difference between solar windows and conventional solar panels
The key factor that allows solar windows to exceed conventional solar panels is their ability to use the acres of glass often used in skyscrapers, while using natural light, shadows, and artificial light to generate energy. On the other hand, solar panels can only use a small space on the roof, which is not enough to meet the high demand of buildings. In addition, by using vertical space, we can save land area for further power generation.

Advantages of transparency of solar windows
The beauty of the building in the building is preserved. Traditional solar panels are opaque in nature, and solar windows can maintain the architectural beauty and transparency of windows when generating electricity. On the other hand, solar glass can be integrated into existing window structures in buildings without damaging them.

"Building Integrated Photovoltaic" installs solar panels directly in the building, greatly increasing the surface area of ​​the building available for solar power generation. At present, Grand Glass is conducting a lot of research to develop different types of solar production windows and glass components that can be built directly on the walls. The energy produced can be used to charge electric vehicles and even power safety lights at night.
