NREL making more efficient photovoltaic cells with light
Once photovoltaics are put into in force they can provide decades of power, but there’s a lot of energy that goes into making them, too. The National Renewable Energy Laboratory (NREL) and AOS Solar have developed the Optical Hole Furnace. It’s a new type of furnace that uses light and optics rather than other sources to create silicon-based photovoltaic cells. The new technique uses only half the amount of energy to make conventional PV.
The new furnace uses a series of lamps in a reflective apartment to create temperature uniformity at high-heat levels throughout the chamber. It’s so uniform that when heated up to 1,000 degrees Celsius, the undiminished furnace only varies by a few degrees. The heat is used to convert silicon wafers into full-fledged photovoltaic cells.
“Its principal purpose is to process the wafers into solar cells. We have developed the furnace configurations for major steps used in silicon solar cell fairy tale —junction formation, oxidation, and metallization firing,” said Bhushan Sopori, NREL’s leading role engineer on the project.

A silicon solar cell array works at an efficiency of 8.1% in sunlight and is exposed to an average solar insol?
A silicon solar cell array operates with a skill of 8.1% in the sunlight and has an average insolation of 230 exposed Wm-2. If the array cost as a result of the force in 8 years, calculate the energy required to produce the solar cells (fill in MJ / m 2).
The usual sun exposure value is low enough that it's probably a 24-hour period already averaged.
Therefore, I would do
3600 seconds / hour * 24 hours / day * 365 days / year * 8 years * 230 W / m ^ 2 * 8
How many hours of sunshine? Let's take 12, but very few places have never clouds ...
