Project Report For Solar Photovoltaic Power Plant

Monocrystalline solar cells: This form of solar cell is constructed from thin silicon wafers cut from artificially manufactured crystals. Because they are formed from single crystals grown in isolation, these cells are the most expensive of the three (approximately 35% more expensive than comparable polycrystalline cells), but they have the highest efficiency rating – between 15 and 24 percent.

Polycrystalline solar cells: Such a type of solar cell is likewise created from thin wafers of silicon cut from artificially grown crystals, but instead of single crystals, these cells are constructed from several interlocking silicon crystals grown together. This makes them less expensive to manufacture, but their efficiency is lower than that of monocrystalline solar cells, which is now 13-18%.

Amorphous solar cells: These are the cheapest solar cells to manufacture, are relatively new to the market, and are manufactured quite differently than the other two varieties. Instead of utilising crystals, silicon is thinly placed on a backing substrate. The amorphous solar cell has two significant advantages: first, the silicon layer is so thin that the solar cells are flexible, and second, they are more efficient at low light levels (such as during the winter).

Hybrid solar cells: It is a hybrid of amorphous and monocrystalline solar cells. These have higher efficiency ratings than the combined total of the other three types of solar cells and are referred to as HIT solar cells (Heterojunction with Intrinsic Thin Layer, a mouthful!). Furthermore, they perform better in hotter climates, where temperatures frequently surpass 250 degrees Celsius, producing up to 10% more power. We believe that polycrystalline cells are the best solution in many circumstances since they offer good value while being reasonably efficient.
