Conversion efficiency higher U. S. and British pushing perovskite solar cells

From the point of scale effect and utilization, electrochemical energy storage in the grid side and supply side can be more concentrated and large-scale use, a user side energy storage efficiency is high, and stronger security and controllability, abroad in power supply side and grid side are introduced a large number of incentive policy, our country also should draw lessons from international experience, in terms of grid side and supply side energy storage strengthen policy support and guidance.

in 2009, Japanese researchers perovskite first be applied to the production of solar panels, not only low efficiency at the beginning, also is very unstable, cannot be produced extensively, but after nine years of time, at the beginning of efforts have paid off, and now the perovskite cell ( 钙钛矿细胞) Is seen as a solar panel star of tomorrow, not only has a higher than existing technology of photovoltaic conversion efficiency, costs are relatively low.

according to a report the TechCrunch, Britain's Oxford PV solar power company is now in the world's highest efficiency of the perovskite cell records, can be turned 27. 3% of the solar energy, even more than it is now the main single crystal solar panels by 4%.

in earlier this year, the British government provided a $30 billion fund to Oxford PV, let them continue to study the application of perovskite battery. Two days ago, according to documents received by the U. S. securities and exchange commission, the United States a company named Swift Solar also raised $7 million, hoping to turn the same technology to market.

the Swift Solar, co-founder and chief scientific guiding Sam Stranks said in a speech that perovskite allowed them to rethink these silicon Solar panels on the roof can have any other performance, and he felt the most excited is, making the cost of these batteries will be very cheap, is now making the other half of the Solar energy materials.

the production of solar panels of chemicals was highly regarded in the past, but the cost was too high, make commercial goal difficult to achieve, many manufacturers are finally directly in half, but those who survived the manufacturer or try to maintain their dominance in the industry.

the TechCrunch believes that although the technology is still have risk, but efficiency quickly make cost is low, to attract buyers and investors again.

but now, Oxford PV is developing conversion rate can reach 37% of the solar cell, polycrystalline PV than existing or silicon thin film solar panels more efficient.

the Oxford PV technology officer Chris Case, said the current commercial perovskite crystal silicon solar cells has been in trial production, they are also in the optimization of related equipment and the production process, prepare the way for commercialization.
