Singaporean startup unveils illumination tech that ‘rejuvenates’ solar panels

NTU Singapore researchers and startup EtaVolt have presented a high-intensity illumination device that can reportedly “patch up” the holes caused by light and heat in silicon solar cells. The new technique is claimed to reduce solar module degradation by up to five years and to be usable for about 90% of the solar modules available in the market.

Control tech for modular gravity storage

A group of researchers in China has developed an energy management system for modular gravity storage. Compared to single block gravity storage, the modular counterpart offers more flexibility in output power, ease of mass production of related equipment and better flexibility in the selection of weights.

Master-slave technique for deploying parallel inverters in PV systems

Scientists in Czechia have proposed to use parallel inverters in PV systems to not only reduce instability, but also to increase power yield. The proposed approach reportedly results in higher maximum power point tracking (MPPT) performance.

Waste heat from PV panels used to generate residential hot water

Scientists in the United States has developed a new photovoltaic-thermal system design that utilises parallel water pipes as a cooling system to reduce the operating temperature of photovoltaic panels. The waste heat generated by this process is then used to generate domestic hot water.

Bifacial PV on rooftops can provide energy yield gains of up to 22.6%

Scientists in Australia have combined Monte Carlo Ray Trace (MCRT) techniques and electrical modelling to assess the potential energy gains of bifacial rooftop PV systems compared to monofacial arrays. They found that rooftop reflectivity is a key factor in increasing a bifacial PV system performance, and that system and module design should also be carefully considered.

Reconfigurable series-parallel photovoltaic modules with high shading tolerance

TU Deflt researchers made a first attempt to validate reconfigurable solar modules using prototypes in outdoor tests. The panels consist of two or more blocks of solar cells that are connected to a switching matrix and reportedly achieve a 10.2% higher energy yield than conventional shade-resilient modules under partial shading conditions.

Martin Green’s solar cell efficiencies at a glance – updated

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.

Nuclear who?

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.
