In the 1950s it became possible to produce pure silicon crystals. Since the photovoltaic effect in these crystals was significantly greater, the effect was first used in light sensors.
A further boost for the application was space research, where large-area silicon elements provided power to satellites. Today, solar cells are again the focus of research, as they provide an alternative to coal, gas or nuclear power.
In this first part you experience in 8 experiments the photovoltaic effect in semiconductors. To do this you use solar cells and photodiodes.
In the second part (Go on...) you experience in 8 more experiments applications of the photovoltaic effect.
Let's go...and have fun...
