Chinese researchers have developed a solar cell using CsSnI3 perovskite, known for its unique phase transitions and near-IR emissions. By simulating the device with various electron transport layers (ETLs) and hole transport layers (HTLs), they determined that the optimal cell could be created using a titanium oxide (TiO2) ETL and a nickel(II) oxide (NiOx) HTL.

A new generation of flexible, lightweight modules is entering the market. With back contact technology offering its own form of design flexibility and robustness, the new products could crack a hard-to-address market segment, as Jonathan Gifford explains.

Sharp’s new IEC61215- and IEC61730-certified solar panel offers a power conversion efficiency of 22.07% and a bifaciality of more than 80%. The operating temperature coefficient is -0.30% per C and its power tolerance is 5%.

Hungarian company SolServices has published a white paper outlining ways to make solar farms more compatible with nature and wildlife, from insects and amphibians to birds, bats, rodents and big game.

The Australian government has presented its 2023-2024 budget, with $2 billion (USD 1.35 billion) to be invested in hydrogen, while Austria, Germany, and Italy said they have started moving forward on a southern hydrogen corridor from North Africa to Northern Europe.

University of New South Wales researchers have identified four failure modes caused by damp heat in heterojunction solar panels with a glass-back sheet configuration. The failures could result in power losses ranging from 5% to 50%.

Researchers at the VTT Technical Research Centre of Finland said that chemical energy storages were needed for short and long-term balancing in every climate region, especially in the northern climates. Meanwhile, companies are moving forward with their plans to produce hydrogen in Namibia and Morocco.

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.

JinkoSolar, Long, JA Solar, and Trina Solar have all reported impressive growth figures for the first quarter of this year.

The International Renewable Energy Agency has released new data on the cost of capital for solar PV, onshore and offshore wind in the period between 2020 and 2021. Results show that Australia has the second lowest cost of capital in the Asia Pacific region at 4.6%, beaten out by China at 3.9%.
