The first generation of solar cells refers to the earliest types of photovoltaic (PV) cells that were developed for converting sunlight into electricity. These solar cells primarily used crystalline silicon (c-Si) as the semiconductor material. First-generation solar cells played a crucial role in the early development of solar energy technology and set the foundation for modern solar power applications.

First-generation solar cells were developed in the 1950s when scientists at Bell Laboratories in the United States created the first practical silicon-based solar cell. These cells were based on the photovoltaic effect, a phenomenon in which certain materials generate an electric current when exposed to sunlight. The silicon material used in these solar cells was chosen due to its abundance, stability, and excellent ________ _____ ___ ____ ____ ________ _______ ________ ___.
