We've recently attained 40% efficiency with solid photovoltaic cell arrays. Not sure who told them that 19% was where we are at, but it's not accurate. Unless this is an aged article.
Re: 40% efficiency with solid photovoltaic cell arrays, In the case of smaller solor cells it is not required that you have 100% engery output, as they will not be used for large scale energy production.
therefore' they do not need to be as efficient as those used to produce large scale electricity.
The printable solar cells panels aswell as the The spray-on solar panels, can be used on almost any surface say for the purpose of watching television advertising on the side of a bus or even on the side of a soft drink can.

SYDNEY: An Australian researcher who led the development of the world's highest efficiency silicon solar cells has been named the inaugural Scientist of the Year by the state of New South Wales.
Martin Green, a professor at the University of New South Wales in Sydney, won the award for his group's contributions to photovoltaic technologies, including the development of high-gain silicon solar cells -
cleantechnica.com — Spray-on tans, spray-on solar panels …what’s next? Researchers at the Australian National University are working with Spark Solar Australia and Braggone Oy on a three-year project to develop spray-on solar panels that are cheap and highly efficient.
