Shedding light on tandem perovskite solar cell progress

Perovskite PV devices are set to become the next big thing in solar with market analysts at S&P Global Commodity Insights predicting 1 GW of production by the end of 2024, rising to 6 GW in 2025. Perovskite tandem devices are at the front of the queue for commercialization but their characterization presents technical challenges.

Tesla’s new power play

The first installations featuring the Tesla Powerwall 3 are currently being completed in the United States, with the company promoting a fully integrated solar-plus-storage and electric vehicle (EV) residential system, with big backup power capacity. While the first Powerwall created a new market segment, the latest iteration enters a marketplace in oversupply.

The long read: Thin prospects

The production of PV ingots and wafers remains the most highly concentrated of all the production stages in the silicon solar supply chain. Yet efforts to re-establish production in Europe and the United States are not for the faint-hearted.

Rooftop solar’s success results in ‘struggling’ large-scale segment in Australia

As rooftop solar racks up records in Australia, price cannibalization has resulted in a “struggling” large-scale market segment. Bruce Mountain, head of the University of Victoria’s Energy Policy Centre, says that increasingly depressed wholesale electricity prices during the day are squeezing out big PV.

Connecting HJT

The application of busbarless cell interconnection approaches could unlock the potential of heterojunction (HJT) technology, primarily by reducing the historically high silver usage of negatively-doped, “n-type” cell technology. As HJT manufacturing increases, a wave of applications may very well be on the horizon.

Shingle all the way

While shingled cells have been around for a while, Tongwei’s adoption of the technology is notable as it is a manufacturer with considerable scale. If shingling can overcome some hurdles, it could prove a welcome solution as unshaded sites for PV become elusive in mature solar markets.

The long read: Putting solar capital to work

Venture capital investment in solar and energy storage companies in sub-Saharan Africa brings with it considerable risk, but also holds the promise of making an outsized impact in delivering clean energy access. KawiSafi Ventures Managing Director Amar Inamdar says that venture capital investment in frontier markets will be a key part of the “capital stack” required to pursue the joint goals of leapfrogging fossil fuel energy development in the continent and lighting up African lives.

The long read: Clear winds of renewables change

After a decade of under-delivering on its potential, there are changes afoot in Southeast Asia’s renewable energy development, says Assaad W. Razzouk, the CEO of Singapore-based developer Gurin Energy. Razzouk points to success stories in the region and notes that political will and clear regulations for developers are needed.
