Solar energy is the Future

(3) Solar photovoltaics keeps growing fast—faster than any other power technology. Collective installed PV capability worldwide has actually doubled every 2 yrs (43per cent CAGR) because the year 2000, reaching ~200 gigawatts-peak (GWp) in 2014.

Only for fun, listed here is the naive extrapolation:
That said, solar PV taken into account only ~1% of our total electrical energy usage a year ago, generally there's obviously many headroom kept.
OK.

But just how can we switch sunlight into of good use energy? What’s the future of PV? And tend to be there various other non-PV solar power technologies in the R&D pipeline?
Let’s mention technology.
Solar Photovoltaics (PV)
Solar photovoltaics (aka "solar cells") tend to be definitely the key solar power technology when it comes to total deployment*. PV is very nice: It really is undoubtedly modular (just one PV component is not any less efficient than a large variety), it runs quietly as well as reasonable conditions, therefore does not require much maintenance over its 25+ year life time.
*Aside from solar heaters, which are made use of extensively in China for heating domestic liquid and in the U.S. for keeping pools hot. Solar power home heating can’t be contrasted directly with PV since its result is temperature [GW-thermal] versus electricity [GW-electric].
We typically name PV technologies by the product (or content course) regularly absorb light: crystalline silicon (c-Si), gallium arsenide (GaAs), hydrogenated amorphous silicon (a-Si:H), cadmium telluride (CdTe), copper indium gallium diselenide (CIGS), copper zinc tin sulfide (CZTS), organics, perovskites, or colloidal quantum dots (QDs), to name a few.
It's convenient to take into account these technologies regarding material complexity, which corresponds roughly toward few atoms in a device mobile, molecule, or other repeating product of a product [4, 5]. Material complexity relates to their education of disorder in the nanoscale. For current PV technologies, higher product complexity frequently translates to lower technical readiness, products make use of, processing conditions, and processing complexity. These traits frequently open up brand new applications by allowing book technical qualities, like visible transparency, flexibility, and brand new type facets.
With PV technologies, it is difficult to predict what's going to become lasting winner.
