Modules & Upstream Manufacturing

Falling module prices will help PV post another record year after an estimated 132 GW was installed worldwide in 2020, according to an energy transition investment trends report published by Bloomberg New Energy Finance.

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.

Iranian scientists have assessed a new active approach for solar module cooling based on water spraying. Water sprayed from different angles can reduce the operating temperature of PV modules, with limited water consumption. However, the team noted that they have yet to assess the economic viability of the system.

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.

Western Australia-based solar glass developer ClearVue has commenced installation of its transparent solar PV glazing panels at what will be the world’s first clear solar glass greenhouse.

Huawei has strengthened its technology partnership with Chint, while TBEA is planning an IPO for its polysilicon unit Xinte Energy. Furthermore, glass manufacturers keep acting to overcome current bottleneck.

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.

The German research institute has proposed a technique based on the surface structure of the wings of the morpho butterfly to produce colored BIPV panels for facades and rooftops. The process is claimed to make it possible to color the modules with an optical effect and not with color pigments, which reduce their efficiency.

Some 15% of the finance disbursed must fit the wider definition of being ‘sustainable’ and banks and other lenders have been warned penalties will be applied for non compliance.
