A solar panel battery is actually a set of separate (photovoltaic) solar cells arranged together. These cells have the ability to convert sunlight into electricity. This is very different from ordinary batteries, which convert chemical energy into electricity. While such batteries have the ability to store energy (in the form of chemicals), solar panels must rely on external storage.

Solar cells consist of a certain type of semiconductor treated with impurities – they become very sensitive to light. It is a medium that causes electrons to move toward one end of the material, creating a potential difference – also known as voltage. Scientists discovered this phenomenon by accident. Humanity soon realized the potential of their invention and searched for better materials for producing more efficient photovoltaic cells.
The first solar cells were part of a one-component semiconductor made of silicon. The production of these solar cells requires a huge amount of energy, which is why they are very expensive. Scientists then succeeded in making various forms of photovoltaic materials. Some of them are cadmium telluride (CdTe), copper-indium-gallium-selenide, amorphous silicon, and neuromorphic silicon.
Engineers have also discovered that this new material can be applied to thin pieces of glass or ceramic. This reduces the mass of the solar cell. Better materials in combination with better manufacturing processes do not promise higher energy conversion but reduce production costs. This certainly helps introduce solar panels to household consumers.
The efficiency of photovoltaic cells (as we know them today) is almost 20%. Studies show that one day more research could push that figure to 60%. However, there are theories that have proven that this is impossible…no one really knows. But we believe that we can increase the efficiency of photovoltaic cells by using more of the solar spectrum by using ultraviolet and infrared wavelengths.
