The drive for more powerful solar technology emphasizes the importance of future cost reductions for advancing the shift away from fossil fuels.
FREMONT, CA: The solar industry has invested centuries in lowering the cost of solar-powered electricity production directly from the sun. The companies are now concentrating on developing panels much more powerful.
With savings in equipment manufacturing hitting a flat-lining and more recently challenged by growing raw material prices, manufacturers are focusing more on technological advancements, such as better components and more innovative designs to produce more power from the same-sized solar farms.

The first two decades of the twenty-first century saw massive price drops in modules, but the rate of decline has slowed substantially in the last two years. Fortunately, new technology will result in additional decreases in the cost of electricity.
Solar Slide
The drive for more efficient solar technology emphasizes the importance of future cost reductions in shifting away from fossil fuels. While grid-scale solar farms are already often less costly than even the most sophisticated coal or gas-fired plants, more savings will be necessary to combine clean energy sources with the expensive storage technology necessary for continuous carbon-free power.
For the solar industry, larger factories, automation, and more effective production processes have resulted in economies of scale, lower labor expenses, and less material waste. The estimated price of a solar panel can be reduced by 90 percent in the future.
Manufacturers can produce a similar amount of electricity from a minor operation by increasing power generation per panel. This is important because land, construction, engineering, and other equipment expenses have declined similarly to panel prices.
Here are few ways that solar companies are super-charging panels:
Perovskite
While several present breakthroughs are just adjustments to old technologies, perovskite can be a true game-changer. Perovskite, thinner and more transparent than the standard material polysilicon, might be placed on top of current solar panels to improve efficiency or merged with glass to create power-generating building windows.
Bi-facial Panels
Solar panels usually acquire their energy from the part which faces the sun, but they can also utilize the light that reflects from the ground. In recent years, the bi-facial panels began to gain prominence, with manufacturers aiming to collect the extra electricity increments by changing opaque backing.
Doped Polysilicon
Another improvement that can result in more power is switching from positively charged silicon to negatively charged, or n-type, silicon for solar panels. Polysilicon is loaded with a small quantity of an element with an additional electron, such as phosphorous, to produce N-type material.
