Modules & Upstream Manufacturing

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.

Coming up at Moda village in Valsad district, this will be Waaree’s third solar modules investment in Gujarat after Surat and Umargam plants.

Consultancy Bridge to India has looked into its crystal ball to predict India will add 10 GW of solar capacity this year and the same next year before deployment slows to 7 GW per year in 2022 and 2023, dogged by hurdles such as an inexplicable ongoing demand for new coal-fired power plants.

Delay in sourcing of PV modules from China can cause project cost and time overruns, inviting penalties for missing the commissioning date.

The state-owned engineer has specified the dimensions of the devices required and the bid window will close on Friday.

Solar module manufacturers should begin testing new technologies in higher-value niche markets, say scientists at the U.S. institution. For example, bringing perovskite technology directly to the mainstream market remains prohibitive in terms of initial investment but segments such as building-integrated PV or microelectronics devices may offer better routes to commercial maturity.
