A. Nowadays humanity is solving the problem of natural resources and environmentally friendly power manufacturing. In order to find the solution to these issues, solar energy plants are becoming widely used. However, solar panels are not so effective as traditional energy plants, like hydroelectric or nuclear power plants. If traditional energy plants didn’t damage the environment badly, scientists wouldn’t need to find new decisions.

B. Scientists are trying to find ways to increase the efficiency of solar panels by using various materials and designing advanced technology. One of the newest materials to use is perovskite. Scientists got interested in this material due to its lower level of light absorption, which ensures maximum energy output to the outside.

C. One of the technologies suggested by engineers is sun tracking. They noticed that some plants move in the direction of the sun, because it heats the surface of the plants more if sun rays fall at the right angle. The phenomenon of plants tracking the sun's motion to increase light absorption is called heliotropism. This biological habit is simulated in the construction of solar panel holders. If scientists use the chemical features of perovskite with such construction, it will reduce the cost and increase the efficiency of solar panels.
