The 5x5cm device was developed by a Japanese research group. The thickness of the perovskite films was increased to reduce defects and pinholes and this was achieved by adding ammonium chloride to the lead iodine solution used in the formation of the films. The device was able to work for 1,600 hours at more than 80% of this efficiency.

Furthermore, Risen predicts its solar module shipments will reach 15 GW this year and Sze Tan Hung has increased her stake in solar cell and panel maker Solargiga.

The interconnection tech, developed by scientists at the Belgian research institute Imec, is based on a three-dimensional fabric of encapsulant with incorporated horizontal and vertical solder‐coated metal ribbons. Mini solar modules built with the proposed technique have provided interesting results in tests for thermal cycling reliability, showing very limited degradation.

Longi and Risen both announced plans to build up new module and cell manufacturing capacity. Furthermore, the State Power Investment Corporation (SPIC) has revealed it deployed more than 10 GW of solar power last year.

Scientists in Spain and Colombia took a closer look at the degradation mechanisms affecting perovskite solar cells, and developed a new, high throughput method to characterize their performance in an outdoor setting. The group evaluated the method through outdoor testing on perovskite modules manufactured in a lab. it expects its findings to offer easier device characterization and better understanding of the degradation mechanisms affecting perovskite solar cells, both important factors in the technology’s development.

German scientists have designed a manufacturing process to reduce the thickness of the molybdenum diselenide interface layer in kesterite solar cells. They used two different configurations of silicon-oxynitride diffusion-barrier layers.

German scientists have fabricated an enhanced amorphous germanium PV cell that confines light in an ultra-thin absorber. It has the potential to combine PV with photosynthesis in new solar applications on bio-reactors, greenhouses, and agricultural land.

Australian scientists have built a perovskite solar cell based on 2D and 3D salts. By adding a fluorinated lead salt in the processing solution – normally used to form 3D methylammonium lead iodide – they were able to achieve a 21.1% efficiency, an open-circuit voltage of 1.12 V, a short-circuit current of 22.4 mA/cm2, and a fill factor of 84%.

Italian researchers have engineered a hole extraction layer with water-splitting additives to reduce the impact of moisture in perovskite PV devices. They claim that the method ensured a power conversion efficiency of more than 9% in perovskite cells stored for a month in a water-saturated atmosphere.

Trina Solar has secured a 4 GW solar module order from US company Nextera Energy and wafer manufacturer JYT Corporation closed deals to supply a total of 1,906,000,000 wafers.
