What are solar panels made of?

not sure knowledge know purpose save solar cells later created energy
solar energy generated solar panels. solar panels slabs of semi-conductor metal. technically speaking, slab of silicon semi-conductor doped or added impurities make better conductor. solar panels made of gallium arsenide semi-conductor metal exclusively used in photo-voltaic cells.
silicon slabs polished , glossed before doping. after processing, protection, thin glass layer embossed on solar cells slab. silicon shiny , reflects 35% of sunlight. hence, anti-reflective coating applied on slabs reduce amount of sunlight lost. amorphous silicon solar panels different traditional ones made silicon slabs. amorphous silicon solar cells thinner , more efficient silicon ones , materials cost of variety far lesser traditional. amorphous silicon slabs developed superior processes makes them less susceptible breakage during transportation. makes them more viable investment when comes buying solar panels.

(for project)
know made of silicon, want made of. ex metal (what kind)
please tell me used production finished project
thank you
