The researchers describe their novel perovskite-silicon solar cell in this week's edition of the

journalEnergy & Environmental Science.

"We've been looking for ways to make solar panels that are more efficient and lower cost," said

study co-author Michael McGehee, a professor of materials science and engineering at

Stanford. "Right now, silicon solar cells dominate the world market, but the power conversion

efficiency of silicon photovoltaics has been stuck at 25 percent for 15 years."

One cost-effective way to improve efficiency is to build a tandem device made of silicon and

another inexpensive photovoltaic material, he said.

"Making low-cost tandems is very desirable," McGehee said. "You simply put one solar cell on

top of the other, and you get more efficiency than either could do by itself. From a commercial

standpoint, it makes a lot of sense to use silicon for the bottom cell. Until recently, we didn't have

a good material for the top cell, then pervoskites came along."

Perovskite is a crystalline material that is inexpensive and easy to produce in the lab. In 2009,

scientists showed that perovskites made of lead, iodide and methylammonium could convert

sunlight into electricity with an efficiency of 3.8 percent. Since then, researchers have achieved

perovskite efficiencies above 20 percent, rivaling commercially available silicon solar cells and

spawning widespread interest among silicon manufacturers.

"Our goal is to leverage the silicon factories that already exist around the world," said Stanford

graduate student Colin Bailie, co-lead author of the study. "With tandem solar cells, you don't

need a billion-dollar capital expenditure to build a new factory. Instead, you can start with a

silicon module and add a layer of perovskite at relatively low cost."

Sunlight to electricity

Solar cells work by converting photons of sunlight into an electric current that moves between

two electrodes. Silicon solar cells generate electricity by absorbing photons of visible and

infrared light, while perovskite cells harvest only the visible part of the solar spectrum where the

photons have more energy.

"Absorbing the high-energy part of the spectrum allows perovskite solar cells to generate more

power per photon of visible light than silicon cells," Bailie said.

A key roadblock to building an efficient perovskite-silicon tandem has been a lack of

transparency.

"Colin had to figure out how to put a transparent electrode on the top so that some photons

could penetrate the perovskite layer and be absorbed by the silicon at the bottom," McGehee

said. "No one had ever made a perovskite solar cell with two transparent electrodes."

Perovskites are easily damaged by heat and readily dissolve in water. This inherent instability

ruled out virtually all of the conventional techniques for applying electrodes onto the perovoskite

solar cell, so Bailie did it manually.

"We used a sheet of plastic with silver nanowires on it," he said. "Then we built a tool that uses

pressure to transfer the nanowires onto the perovskite cell, kind of like a temporary tattoo. You

just need to rub it to transfer the film."

Remarkable efficiency

For the experiment, the Stanford team stacked a perovskite solar cell with an efficiency of a 12.7

percent on top of a low-quality silicon cell with an efficiency of just 11.4 percent.

"By combining two cells with approximately the same efficiency, you can get a very large

efficiency boost," Bailie said.

The results were impressive.
