We already know that concentrated solar power (CSP) is shaking things up in the solar industry. A subset within the industry is turning up the heat. “Extreme” Concentrated solar magnifies intense sunlight onto a solar cell, at temperatures that could melt it, to boost efficiency for less money.
The holy grail of renewable energy is not just efficiency but competitive pricing. Most consumers don’t want to wait 5-10+ years to earn back their investment in energy savings, assuming that they can afford solar. Never mind the added value of generating some of your own energy. Utility-scale facilities hinge not only on cost, but infrastructure. If you build your solar/wind farm in the desert, transmission lines may not come out to meet you. So when someone claims to have a cheap, efficient solar technology, people pay attention.
