How much light engergy is converted to electrical?

The amount of light energy converted to electrical energy varies depending on the efficiency of the technology used. In photovoltaic solar panels, for example, typical conversion efficiencies range from 15% to 22%, meaning that 15-22% of the incident light energy is converted into electrical energy. Advanced technologies, like multi-junction solar cells, can achieve efficiencies over 40% under concentrated sunlight. Overall, the specifics depend on factors such as the type of material and environmental conditions.
