Modules & Upstream Manufacturing

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.

Two French companies have collaborated on the development of the Osmo-Watt system, which is powered by solar panels. They claim that the technology can produce up to 100 cubic meters of drinking water per day.

Scientists in Poland have measured the effect of solar radiation spectra in variable weather conditions on the performance of different kinds of PV module technologies. They found that amorphous silicon panels offer the best response to this effect in stationary or BIPV projects on facades, while crystalline silicon and CIS solar panels represent the best options in projects with trackers.

Researchers in the Middle East have proposed a new passive technology to cool off solar modules, based on highly conductive porous materials.

In many respects, the past year has been unlike any other. But the innovation and ambition driving the expansion of the solar and energy storage industries is one constant that has remained, Across seven categories, pv magazine’s award winners for 2020 demonstrate high levels of technical expertise, creativity, mass production capabilities, and real market impact from PV and power electronics companies big and small. Following on from the virtual award ceremony held this morning, the winners are….

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.
