A few years later, in 1883, Charles Fritts actually produced the first solar cells made from selenium wafers – the reason some historians credit Fritts with the actual invention of solar cells. However, solar cells as we know them today are made with silicon, not selenium. Therefore, some consider the true invention of solar panels to be tied
