Manufacturing

The polysilicon manufacturer says a lack of the raw material is causing a bottleneck for the industry but CEO has predicted it will be resolved as new production capacity comes online in the months ahead.

The Chinese photovoltaic manufacturer said the recent invalidation procedure for its patent at the Chinese Patent Office’s examination and invalidity department is only an administrative examination procedure that only examines whether or not the authorized Chinese patent complies with patent law requirements.

An extensive European Commission regulation has set the bar on those economic activities deemed to help in the war against global heating and, by implication, those which may hinder the effort.

Avinash Hiranandani, global chief executive officer and managing director of RenewSys India, speaks to pv magazine about solar module technology trends and the company’s manufacturing focus.

A British-German research team claims that organic PV technologies may become mature enough to compete with crystalline silicon and thin-film products not only in BIPV, but also in power generation in the electricity market. In order to get there, however, organic PV products will have to achieve higher efficiencies.

Scientists in South Korea demonstrated a perovskite cell with a certified efficiency of 24.4%. The device is claimed to maintain over 80% of its initial efficiency after 1,300 hours in the dark at 85 degrees Celsius.

It is now a well-established trend. After the switch to larger wafer sizes played out in 2019, this year has seen virtually all of the biggest PV manufacturers introduce new modules in dimensions above the 2-meter mark, and with power ratings in excess of 500 W – in some cases, as high as 800 W. As these modules begin to roll off production lines in larger quantities, it’s vital to take a look at the challenges and opportunities they bring to system design, installation, and long-term operation.

Researchers at the University of Malaga say they have developed a panel for building-integrated photovoltaics that improves light absorption without losing efficiency and durability.

Meanwhile, Chinese state-owned energy company State Power Investment Corporation (SPIC) has acquired a solar energy developer in Mexico and JA Solar has started construction on the second phase of its 20 GW ingot factory in Yunnan Province.

Researchers in Australia have conducted extensive research on all possible causes behind the light-elevated temperature-induced degradation (LeTID) in solar panels and presented a few mitigation strategies put in place by manufacturers to reduce its effects.
