However, the efficiency of thermoelectric devices, or the amount of energy they are able to produce, is currently limited.
The Process of Solar Electricity Generation. When sunlight hits a photovoltaic cell, its energy is absorbed by the semiconductor material. This energy excites electrons in the atoms of the material, causing them to break free from their atoms and create electron-hole pairs. The electric field at the p-n junction then separates these electron-hole pairs, causing the …
