The research group led by Professor Martin Green has published Version 63 of the solar cell efficiency tables. There are six new results reported in the new version.

Authors of the “World Nuclear Industry Status Report 2023” define the future role of nuclear energy in the global energy mix as “irrelevant” and “marginal.” The authors add that there were 407 operational reactors producing 365 GW in the middle of the year, which is less than installed capacity predictions for solar by the end of the year.

Sharp’s new IEC61215- and IEC61730-certified solar panels have an operating temperature coefficient of -0.30% per C and a bifaciality factor of over 80%.

Hanwha Qcells has closed its 3.5 GW solar factory in South Korea as part of plans to optimise its PV module production capabilities amid a stagnant domestic solar market.

Wood Mackenzie says in a new report that China could install 230 GW of PV and wind capacity and export more than 200 GW of solar panels in 2023. Unlike Europe and United States, the country is avoiding the high curtailment of PV and wind.

Human Geographer Thilo Wiertz speaks to pv magazine on the particular features that characterised the trajectory of renewable energies after the outbreak of the war in Ukraine. He emphasised how the geopolitical tensions arising from this conflict have reshaped the political debate about the energy transition, with the energy security perspective gaining in importance.

Tim Buckley, director of Climate Energy Finance, speaks to pv magazine about the current steep trajectory of solar module prices. He estimates that PV panels prices will end up dropping by 40% this year and predicts the closure of old technology and sub-scale solar manufacturing facilities, both in China and globally.

A Spanish-Algerian research group has tested how “cool roofs” could help increase power yield in rooftop bifacial PV systems. Cool roofs are based on coating materials with high reflectance properties.

Scientists from South Korea have designed new photovoltaic modules with both rectangular and triangular shapes and solar cells connected in parallel, which they said have higher partial-shading tolerance compared with cells connected in strings. The panels are reportedly less sensitive to partial-shading geometries than shingled modules.

A Dutch-German research team has tested how a series of framed messages may be used to boost PV system sales, addressing both self-interest and environmental concerns, and has found that all the proposed messages are effective at promoting the purchase of solar panel installations.
