Lead absorbing encapsulant for perovskite solar cells
Scientists in the United States developed what they describe as a ‘scotch-tape like’ solution, which can absorb potential lead leakage from perovskite solar cells, preventing the toxic material from entering the environment. The tape, according to the scientists, can easily be integrated with existing encapsulation strategies, and was shown to absorb 99.9% of lead leaked from cells from that were severely damaged.
OCI reports strong sales growth for polysilicon business
High polysilicon prices helped South Korean supplier OCI to achieve strong results in the third quarter. Tight supply and demand conditions will likely continue until the first half of 2022, the company said.
Bifacial tandem perovskite-CdSeTe solar cell with 20% efficiency
Developed by U.S. scientists, the cell is claimed to achieve an equivalent bifacial efficiency of more than 20% with an open-circuit voltage of more than 2 V. The choice of the bifacial architecture is intended at increasing the device’s power yield in order to offset the high costs for producing the CdSeTe sub-cell.
Cadmium sulfide, a poor partner for selenium tandem solar cells
A Danish-German research team has shown that using cadmium sulfide as an n-type partner in heterojunction tandem solar cells based on selenium does not produce satisfying results. The team has discouraged other scientists from following the same path.
Future climate scenarios to adversely affect Australia’s PV capacity
Australia is blessed with an incredible solar resource, but it will be diminished by global warming.
Chinese PV Industry Brief: Daqo wiped debts as poly price continued to rise
The worldwide solar boom is proving so profitable the polysilicon manufacturer is even thinking of turning to PV panels to power its manufacturing operations, rather than cheap coal.
PV system design for low-cost hot water production
Developed by Spanish scientists, the proposed system design is said to be able to achieve water temperatures above 70 degrees Celsius and to cover around 85% of the annual sanitary hot water consumption of a household with six people.
Lead-absorbing encapsulation for 18.5%-efficient mini perovskite solar module
The solar module has an area of 31.5cm2 and is relying on perovskite cells with an efficiency of 22.9%. It was encapsulated with a special ionogel that is claimed to enhance the module’s impact resistivity and stability, as well as to reduce the possibility of lead leakage.
Another Chinese module maker may face WRO enforcement in the U.S., Roth Capital warns
Given the Withhold Release Order (WRO) and the potential anti-circumvention tariff challenges, U.S. module supply risk is material, the analyst firm said in a note to clients.
Analyzing the opportunity for perovskite solar module production in India
Scientists in India conducted a techno-economic analysis for a 100 MW production line for carbon-electrode perovskite solar modules, located in Himachal Pradesh, India. The analysis concludes that, even at the smaller scale, this emerging technology could achieve cost levels comparable with today’s silicon solar products.
