Modules & Upstream Manufacturing

New research from renowned PV scientist Martin Green and colleagues at UNSW reveals that perovskite solar cells may struggle to deal with reverse-bias caused by uneven shading or other issues likely to appear in the field. Both the reverse-bias itself and resulting build up of heat can cause several of the materials commonly used in perovskite solar cells to degrade, and these issues have received only limited attention in research published to date. Solutions, however, are at hand.

Scientists in land-scarce Korea are proposing to use solar trees to build PV installations in forest areas. Although more expensive than conventional ground-mounted facilities, solar plants made of solar trees may capture carbon from forest land and produce energy at the same time.

The ‘cradle-to-cradle’ certification is considered a globally recognized holistic product quality standard. The assessment is made for five categories: material health, recyclability of materials, energy management and CO2 emissions, water management and social responsibility

New research from the University of New South Wales (UNSW) predicts cumulative polysilicon demand of 46-87 Mt will be required to achieve 63.4 TW of PV installed by 2050.

Scientists in Korea built an organic solar cell that is reportedly able to prevent aggregation in photoactive layers. The device could be used for applications in buildings, vehicles, and the Internet of Things.

A long-time customer of First Solar, Intersect Power is expected to be one of the largest buyers and operators of First Solar technology by 2027.

A Chinese-German research group developed the cell with an ink of graphene oxide (GO) mixed with Nafion that can be spin-coated on an n-type silicon wafer to form a high-quality passivating contact scheme. The GO:Nafion layer simultaneously creates a p–n junction with silicon and passivates the surface defects at the GO:silicon interface.

Solar manufacturer Maxeon Solar Technologies has teamed with Adelaide-headquartered solar panel collection and recycling company Reclaim PV Recycling to recover and recycle SunPower branded solar panels in Australia.

Perhaps in anticipation of California’s coming ban on small combustion engines, battery-powered electric lawn mowers have begun to appear in the market. At least one model is equipped with built-in solar power.

Researchers in Malaysia have defined a new parameter to evaluate solar module cooling techniques based on their lifespan effectiveness. They warned that the proposed methodology should be utilized only with standard test conditions, a temperature of 25 C, and a reference PV system without the cooling system.
