Cost of Solar Cells

Solar Cell Costs

Cost is established in cost-per-watt and in cost-per-watt in 24 hours for infrared capable photovoltaic cells. Manufacturing costs are also calculated including the energy required for manufacturing of the cells and modules in a kWh basis. These figures are added to the end price for solar investors and the energy payback is calculated from the point of power plant initialization or connection to the grid. another method of calculating the payback is to use the feed in tariff mechanism in place for
power plant remuneration. Solar-specific feed in tariffs vary worldwide, and even state by state within various countries. The energy payback time will vary depending on the country of application and the level of the feed in tariff.

Slicing costs

University of Utah engineers devised a new way to slice thin wafers of the chemical element germanium for use in the most efficient type of solar power cells. The new method should lower the cost of such cells by reducing the waste and breakage of the brittle semiconductor.

Low-cost solar cell

Dye-sensitized solar cell, and luminescent solar concentrators are considered low-cost solar cells.
This cell is extremely promising because it is made of low-cost materials and does not need elaborate apparatus to manufacture, so it can be made in a DIY way allowing more players to produce it than any other type of solar cell. In bulk it should be significantly less expensive than older solid-state cell designs. It can be engineered into flexible sheets. Although its conversion efficiency is less than the best thin film cells, its price/performance ratio should be high enough to allow it to compete with fossil fuel electrical generation.
