Solar Energy Corp. of India (SECI) has kicked off 2.4 GW of renewables tenders, including a 1.2 GW procurement exercise and a 1.2 GW round.

Scientists in China have tested the influence of panel row spacing in increasing a PV system performance in a full-scale outdoor PV array experimental platform. They found that larger row spacing plays a limited role in improving thermal convection, observing that solar irradiance and wind speed are the key parameters for optimal PV system design.

Solertix claims to have reduced yield losses in cell-to-module scaling by utilizing ultranarrow interconnection of 19.5 μm. It also says the proposed interconnection technique may be used to achieve a 30% efficiency in area-matched 4T tandem designs featuring a perovskite module over a silicon cell.

The latest government installation figures reveal a slower start to the year for the United Kingdom, with small-scale installations accounting for the majority of additions. As the UK General Election approaches, there are calls from industry for the next government to act quickly on the issues hindering capacity expansion.

Researchers from Japan’s Riken Center for Emergent Matter Science have fabricated an organic solar cell that has achieved waterproofness without reducing flexibility. At 3 micrometers thick, it is thought to be the first cell of its kind to survive a washing machine cycle and retain efficiency after multiple cycles.

JinkoSolar says it has achieved a 33.24% efficiency rating for its perovskite-silicon tandem solar cells, confirmed by the Shanghai Institute of Microsystem and Information Technology under the Chinese Academy of Sciences (CAS).

Chinese wafer manufacturer TCL Zhonghuan says it wants to invest around $197.5 million to increase its stake in Maxeon from 22.39% to at least 50.1%. A Maxeon spokesperson told pv magazine that the plan would place the company in a solid financial position.

In a new weekly update for pv magazine, Solcast, a DNV company, reports that a strong polar jet stream and a record-breaking heat dome in May resulted in a stark contrast in irradiance patterns across North America. The western and central USA, along with Mexico, experienced higher than normal irradiance, while the Gulf and East Coast regions faced lower irradiance.

An Indian-US research team has fabricated a four-terminal perovskite-cadmium telluride tandem solar cell by utilizing a highly conductive and sputtered transparent electrode to increase the current density of the bottom cell. The tandem device combines a 18.3%-efficient top perovskite cell and a 19.53%-efficient cadmium telluride bottom device.

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.
