as well as highly efficient photovoltaic cells (known as gallium arsenide photovoltaic cells) to convert that concentrated solar energy into electricity. Though concentrated solar thermal power
Its gallium arsenide photovoltaic cells though more efficient than standard PV cells, are not cheap. Add up construction costs and the costs of the fancy cooling system,
The majority of today's wireless devices use gallium arsenide-based microwave chips due to their superior high-frequency operation and power handling capabilities.
However, gallium arsenide can be environmentally toxic, particularly in the massive quantities of discarded wireless electronics.
"I've made 1, 500 gallium arsenide transistors in a 5-by-6 millimeter chip. Typically for a microwave chip that size,
Typical semiconductor lasers for telecommunication systems made of gallium arsenide for example however are costly and consist of elements from main groups III
