Modules & Upstream Manufacturing

While China continues to be the top solar module exporter to India, Thailand doubled its module exports to India from $55.05 million in 2018-19 to $110.39 million during the first nine months (April-December) of the current fiscal. Vietnam’s module exports to India also rose sharply from $91.97 million to $127.21 million.

The thin-film cell was manufactured through a low-temperature process and doping with alkali elements.

Bids are invited for supply of multi-crystalline solar modules, with peak power output of minimum 325 Wp each, to different substations in various districts of Maharashtra and Uttar Pradesh. Bidding closes on March 5.

Fraunhofer ISE researchers have integrated stress and temperature sensors within a PV module. They claim that the devices cover a very minimal part of the cells, and that their interaction with the module and the cell itself is quite limited. The sensors can be manufactured as part of a regular cell manufacturing process.

Predicting which technological pathway will dominate in solar cell production is somewhat of a fool’s errand. A battle is currently underway between several of solar manufacturing’s big guns regarding both wafer size and p-or-n-type technology, and the outcome remains to be seen.

Researchers from China are proposing to use spent battery lead for creating a perovskite that can be used in the production of solar cells that are based on this promising material. The proposed one-step process, which was tested in the production of a 17.38% efficient perovskite heterojunction cell, is said to be cheaper and less energy-intensive than other recycling processes for waste lead from lead-acid batteries.

A new polymer developed by Indian researchers can mend its own cracks when exposed to ultraviolet light. The unique ability makes it an ideal candidate as a smart coating for photovoltaic solar devices to prevent damages and increase performances.

The U.S. ITC has released a report highlighting changes in the domestic solar cell and module manufacturing industry, showing that while there has been an increase in domestic module manufacturing, the overall program’s success, relative to the $740 million in tariffs, has created little measurable benefit.

A Turkish research team has analyzed how big changes in temperature can affect absorbance, light transmittance and reflectivity in two types of solar glass. The scientists demonstrated lower efficiency in solar cells and the glass itself were attributable to a large number of micro-cracks and deformations on the glass surface.

Lobby group the National Solar Energy Federation of India says around 4 GW of solar plant capacity is likely to be affected by component shortages after the outbreak of the virus in China.
