A closer look at Longi’s world record-breaking, 26.81%-efficient heterojunction solar cell

An international research group led by Longi Central R&D Institute has published a paper describing Longi’s heterojunction solar cell based on a full-size silicon wafer that made a sensation in November, as it beat the long-lasting efficiency record held by Japanese manufacturer Kaneka for years. The researchers attributed the cell efficiency improvement to the implementation of a p-type amorphous silicon hydrogenated layer together with a modified transparent conductive oxides contact, which they said greatly reduced the cell contact resistivity.

Machine learning method to identify residential PV adopters, reduce soft costs

Researchers have defined a new machine learning-based methodology that reportedly reduces customer acquisition costs by about 15% or $0.07/Watt. It is based on an adapted version of the XGBoost algorithm and considers factors such as summer bills, household income, and homeowner’s age, among others.

Solar module prices remain at 13-week low, spread against M10 cell narrows from January high

In a new weekly update for pv magazine, OPIS, a Dow Jones company, provides a quick look at the main price trends in the global PV industry.

Inverted perovskite solar cell achieves 24.8% efficiency via new additive

The additive consists of a molecule known as 4-guanidinobenzoic acid hydrochloride (GBAC), which is a raw material and intermediate commonly utilized in organic synthesis, pharmaceuticals, agrochemicals and dyestuff fields. The solar cell has a p–i–n structure and, thanks to the new additive, showed considerably reduced defect density on the perovskite film, which in turn results in reduced non-radiative recombinations.

India’s IB Solar deploys new 400 MW solar module manufacturing line

The company’s director Abhinav Mahajan told pv magazine the new 400 MW solar panel production line will become operational by July this year. The facility can produce M10, half-cut, 144-cell modules.

Average silver price expected to drop 2% to $21.30 per ounce this year

The US Silver Institute’s “World Silver Survey 2022” report shows that the price of the metal will fall slightly this year despite increasing demand from the PV industry.
