Solargewinnung

Solargewinnung, also known as solar energy harvesting or solar power generation, refers to the process of capturing and converting sunlight into usable energy. The primary method involves photovoltaic (PV) cells, which are semiconductor devices that exhibit the photovoltaic effect. When photons from sunlight strike these cells, they excite electrons, creating an electric current. These PV cells are typically assembled into solar panels, which can then be used in various applications, from small-scale residential power systems to large-scale solar farms.

Another significant method of solargewinnung is solar thermal energy. This process uses mirrors or lenses to concentrate sunlight onto a receiver, heating a fluid. The heated fluid can then be used directly for heating purposes or to produce steam, which drives a turbine to generate electricity. Concentrated solar power (CSP) systems are a prominent example of this technology.

The gained solar energy offers a renewable and clean alternative to fossil fuels, contributing to reduced greenhouse gas emissions and combating climate change. The technology has seen significant advancements, leading to increased efficiency and decreased costs, making solar power increasingly accessible and competitive. Challenges remain in terms of energy storage solutions for periods without sunlight and the land footprint required for large-scale installations, but ongoing research and development continue to address these issues.
