Italian researchers have analyzed different ways to assess the levelized cost of energy (LCoE) of perovskite solar cells and modules. They said a common approach should soon be defined to increase the market maturity of the tech.

The potential of perovskite solar cells and modules is still held back by issues such as stability and efficiency losses when scaling up from cell to module. But Annalisa Bruno, a scientist at Singapore’s Nanyang Technological University, says most of these challenges could be overcome in the near future, with this technology extending from building-integrated PV to conventional solar projects.

Egyptian researchers have used paraffin wax as a phase-change material (PCM) to reduce the operating temperatures of PV modules. They have found that the material improves power yield by more than 15%, compared to a reference module without cooling.

Scientists in Austria have developed a long-term energy storage system that uses regenerative braking to adjust the descent speed of sand in mine shafts and generate electricity.

Researchers and project developers throughout the world are increasingly looking at agrivoltaic installations with vertically oriented solar panels.

An international consortium led by Italy’s Eurac Research launched the Symbiosyst project to adapt PV modules, mounting structures, and maintenance technologies to the needs of various crops in agrivoltaic installations in different climates.

Qatari researchers have looked at the degree to which cleaning robots could threaten the physical integrity of solar panels. They found that cleaning machines have a very minimal impact and that modules of similar sizes tend to exhibit roughly the same amount of vibration.

Chinese researchers have developed a new passivation technique for shingled solar panels based on tunnel oxide passivated contacts (TOPCon) or heterojunction (HJT) tech. It reduces recombination losses in the cell-to-module process and reportedly increases open-circuit voltage, fill factor, and efficiency.

Canadian scientists have developed a new way to measure the energy yield of bifacial PV systems. They said they considered the spectral albedo of ground cover like snow and sand to predict energy gains of up to 2%, in comparison with the International Electrotechnical Commission (IEC) standard.

Japan’s Shintora Kosan has developed a novel water jet technology to recover glass from end-of-life PV modules. It says it can pulverize the solar cells and the backsheets without damaging the glass.
