Modules & Upstream Manufacturing

Researchers in the Middle East have developed a new design for energy systems combining PV power generation with Trombe walls in buildings. They claim their new system configuration with reflective mirrors offers improved overall system efficiency both in terms of heating and electricity production.

Researchers in Austria have analyzed the crack propensity of backsheets made of polypropylene (PP) and have concluded these may be potentially used in solar module manufacturing, unlike co-extruded polyamide backsheets, which caused many headaches to the PV industry in the past. Furthermore, PP backsheets are claimed to have lower stiffness and higher flexibility than their laminated counterparts.

Solar Energy Corp. of India (SECI) has started accepting bids from solar manufacturers to supply 1 GW of PV modules built with domestically manufactured solar cells. Bidding closes on Aug. 17.

Scientists in Cyprus evaluated six different models used to predict the power losses caused by the accumulation of dust, dirt, and other substances on the surface of PV panels in the island’s arid climate. Results from the various models were compared with soiling loss data from a “test bench” installation at the University of Cyprus in Nicosia, revealing a potential advantage for machine-learning approaches backed by satellite data.

JinkoSolar says that its solar panel shipments reached 30 GW in the first of this year.

In this exclusive interview with pv magazine, Guoguang Chen, President of Smart PV & ESS Business at Huawei Digital Power, in this, discusses company strategy and recent announcements around FusionSolar, latest technology and product innovations in solar and storage, and more.

US scientists developed a monocrystalline solar panel relying on “minicells” based on polysilicon on silicon oxide passivating contacts. The module works with laser light and can reportedly achieve a photoconversion efficiency of over 40% and an open-circuit voltage of 7 V.

The National Renewable Energy Laboratory (NREL) has made highly bifacial perovskite cells with a front-side efficiency of 23%.

French eco-organization Soren, which collects and recycles end-of-life solar panels, has published its 2022 annual report. Last year, more than 10 million solar panels were put on the market in France, up 25% from 2021.

A Chinese-Swiss research group has fabricated a 2D-3D perovskite solar cell with a world-record power conversion efficiency. The cell uses a 2D perovskite layer at the interface between the perovskite and the hole transport layer, which the researchers said can improve charge-carrier transport/extraction while suppressing ion migration.
