Is Selenium Still Used In Solar Panels

By adding cells to the outside of the body the mission time could be extended with no major changes to the spacecraft or its power systems.

Is selenium still used in solar panels. Cdte panels have been found to produce electricity at lower costs than silicon panels and there has been a dramatic gain in efficiency brought about by adding an element called selenium to the cadmium telluride. A team at the lawrence berkeley national laboratory in berkeley california embedded selenium in zinc oxide a relatively inexpensive material that could be promising for solar power conversion. Five lights would utilize 300w in an hour. By embedding the element selenium in zinc oxide researchers have made a relatively inexpensive material that could be promising for solar power conversion by making more efficient use of the sun.

As a result electricity from cdte solar farms is being produced more cheaply than it is from fossil fuels. Research teams have announced that the use of nickel and selenium in the production of solar cells could make them less expensive and more efficient. This secure power supply will provide up to 2000w of energy. A bioplastic used in a solar cell is built to last for the typical 25 year life of the cell.

Vanguard i the first solar powered satellite was launched with a 0 1w 100 cm solar panel. 1959 hoffman electronics creates a 10 efficient commercial solar cell and introduces the use of a grid contact reducing the cell s resistance. So most dismissed them from the realm of further scientific inquiry. It must be able to withstand the high temperatures generated by photovolatic modules and be water tight.

For comparison a 60w light bulb will use 60w in an hour.
