Perovskite solar cells

GreatCell achieves 32% efficiency for inorganic perovskite solar cell

Australian manufacturer GreatCell has built a cell with roll-to-roll coating technology. It designed it without a hole transport layer (HTL) and used carbon composite back contacts, which offer excellent electrical conductivity.

Reliance New Energy to invest in perovskite solar startup Caelux

The new energy arm of Reliance Industries has signed the agreement to acquire a 20% stake in California-based perovskite solar startup Caelux for $12 million. The investment will accelerate Caelux’ product development and commercialization.


Solar perovskite tandems and potential-induced degradation

Scientists have found that perovskite solar cells and perovskite-silicon tandems might be vulnerable to potential-induced degradation. They exposed tandem cell devices to PID stress and found that they lost as much as 50% of their initial performance after just one day.

The economics of perovskite solar manufacturing

Scientists in Switzerland put together a detailed analysis of the projected costs of designing and operating a 100 MW perovskite solar cell production line in various locations, taking in labor and energy costs as well as all materials and processing. The found that perovskite PV could be cost-competitive with other technologies even at much smaller scale, but noted that this still depends on the tech proving its long-term stability, and impressive achievements in research being successfully transferred to commercial production.


Perovskite: The disruptive element

Perovskite solar cells have the potential to produce more energy at significantly lower costs than conventional silicon PV cells. Efforts are underway to speed up their commercialization by addressing issues such as limited stability.

CEA-INES develops 18.95%-efficient flexible perovskite solar panels

French researchers have developed PV modules with an area of 11.6 square centimeters for indoor applications. They said the achieved efficiency level marks a world record for a flexible perovskite device larger than 10 square centimeters.

Perovskite solar cell technology on the road to commercialization

A new US Department of Energy report describes the challenges of commercializing perovskite technology for the solar energy sector.


IIT Bhilai researchers develop large-area perovskite solar cell with copper metal contact

An Indian research group has built a perovskite cell that has a metal contact based on copper, instead of expensive gold. The device showed almost the same efficiency as a cell developed with gold metallization but its stability was much lower. In order to overcome this issue, the scientists suggest using a metal contact made of a thin layer of gold and a thicker, overlying copper layer.

1366 Technologies merges with Hunt Perovskite Technologies

U.S. thin-film manufacturer First Solar and Bill Gates-owned Breakthrough Energy Ventures (BEV) are among the investors in the new company, which is called CubicPV and is expected to develop multi-junction perovskite solar cells with efficiencies of around 30%.

Flexible perovskite solar cell with 21.0% efficiency, high durability

International researchers have placed a low-dimensional metal-halide perovskite capping layer on top of a metal-halide perovskite film to provide hermetically sealed encapsulation and enhanced photocarrier properties. The cell has a short-circuit current density of 23.5 mA.cm2, an open-circuit voltage of 1.15 V, and a fill factor of 0.779.
