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%.

JinkoSolar announces perovskite cell technology platform promising efficiencies close to 30%

The announcement was given by the Chinese module maker in its financial statement for the first quarter of the year. The company also stated it shipped 5.35 GW of PV products in the period from January to March and that its revenue and profits declined by 6.4% and 21.7% year-on-year, respectively.


A crowning achievement for perovskite stability

Scientists in Switzerland demonstrated a new type of nanoscale doping for perovskite solar cells. By both improving stability and reducing the chance of the cells leaking any toxic lead into the environment, the discovery addresses two of the largest remaining challenges to the development of the promising class of cell materials.

Lead halide perovskite cell based on benzodithiophene cation achieves 14.7% efficiency

Swiss researchers sought for the first time to replace phenylethylammonium (PEA) with benzodithiophene (BDT) in cations for perovskite cells. The latter showed improved stability and ensured a power conversion efficiency that was 1% higher than that of its counterpart.

New perovskite material for 23.5%-efficient solar cell

Researchers in Japan have found a new way to fabricate one of the most promising perovskite materials for PV application — the α-formamidinium lead iodide known as α-FAPbI3. With a pre-synthesized version of this material, they were able to produce a cell with a power conversion efficiency of 23.5% and a lifespan of more than 2,000 hours.

Black perovskite solar cell with 15% efficiency via thermal evaporation

The cell exhibited an open-circuit voltage of 1.1 V and was able to retain around 90% of its initial performance after 215 days of exposure to dim light at room temperature. According to its creators, this performance and the notable stability were ensured by the thermal evaporation technique used for depositing the perovskite layers onto the cell.

Flexible perovskite solar module with 10.5% efficiency

The methylammonium-free inverted solar module was built on a flexible substrate made of polyethylene terephthalate (PET). A hole transporting material made of poly(triarylamine) (PTAA) and a double-cation cesium formamidinium (CsFA) perovskite layer were deposited through blade-coating and nitrogen-assisted blade-coating.

Saule Technologies opens perovskite solar cell factory in Poland

The Polish perovskite solar cell specialist claims to be the first company in the world to have commissioned commercial production of the technology.


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.


Perovskite solar panel with 16.1% efficiency via ambient air blade-coating

The panel, fabricated by scientists in Italy, is composed of five series-connected cells, each with an area of 2.01 cm² and has an aperture area of 11 cm². It showed a power conversion efficiency of 16.1%, an open-circuit voltage of 5.59 V, a short-circuit current of 37 mA, and a fill factor of 72.5%.
