Alexandre-Edmond Becquerel (1820–1891): The French physicist who first discovered the photovoltaic effect in 1839, laying the foundation for solar cell technology. Charles Fritts (1850–1903): American inventor credited with creating the first true solar cell in 1883, using a thin layer of selenium coated with gold.
The construction of a solar cell is very simple. A thin p-type semiconductor layer is deposited on top of a thick n-type layer. Electrodes from both the layers are developed for making contacts. A thin electrode on the top of the p-type semiconductor layer is formed. This electrode does not obstruct light to reach the thin p-type layer.
Here are some notable applications of solar cells: Residential Solar Power: Solar panels installed on rooftops of homes generate electricity for household consumption. Excess energy can be fed back into the grid or stored for later use, reducing electricity bills and reliance on non-renewable energy sources.
The diverse applications of solar cells underscore their potential to reshape energy systems, drive environmental sustainability, and enhance resilience in various sectors worldwide. Solar cell is a device which converts solar energy into electrical energy without using any chemicals or moving parts.
