WW says:

There are 3 main types of solar cells.
Mono-crystalline silicon is the most efficient and therefore produces the smallest solar cells for a given power, but are the most expensive.
Poly-crystalline (or multi-crystalline) silicon produces the best compromise between performance and cost, as it is the next most efficient type of solar cell. Recent improvements technology are bringing these modules closer to monocrystalline in size, efficiency and heat tolerance characteristics.
Amorphous (or thin-film) silicon uses the least amount of silicon, are the cheapest, but are also the least efficient.
