Researchers led by Germany’s TÜV Rheinland have created a database of technical risks and mitigation measures for PV installations. Their broad overview of quantification methods has shown that further standardization is required.

A new scientific paper takes a closer look at the record-breaking efficiency that Australia’s Sundrive announced for a silver-free heterojunction cell in September 2021, as certified by Germany’s Institute for Solar Energy Research.

The Asia Europe Clean Energy (Solar) Advisory revealed that most of the planned new solar cell production capacity relates to high-efficiency n-type cell technologies such as TOPCon and HJT.

Spanish scientists have built a cooling system featuring heat exchangers on solar panels and U-shape heat exchangers installed in a borehole at a depth of 15 meters. The researchers claim that this reduces panel temperatures by up to 17%, while improving performance by about 11%.

Scientists in China have designed a new methodology to simulate the near-surface climate of utility-scale PV plants. Their findings suggest that the new tool could be used to design more climate-friendly solar parks.

Australian manufacturer GreatCell has built a cell with roll-to-roll coating technology. It designed it without a hole transport layer (HTL) and used carbon composite back contacts, which offer excellent electrical conductivity.

JinkoSolar has set another world record for n-type solar cell efficiencies with its TOPCon technology, this time reaching 26.1%. The new record was confirmed by China’s National Institute of Metrology.

The government of the Philippines has introduced a new preferential dispatch policy for renewable energy in the country’s wholesale electricity spot market. It has also started to amend the Renewable Energy Act to remove a 40% ownership cap on foreign investments in clean energy projects.

The Chinese Academy of Sciences has switched on a 100 MW compressed air energy storage system in China’s Hebei province. The facility can store more than 132 million kWh of electricity per year.

Enel Green Power’s new solar panel has average efficiencies ranging from 22.6% to 22.9% and a temperature coefficient of -0.24% per degree Celsius. It is based on an n-type solar cell with G12 format and a power conversion efficiency of 24.6%.
