COVER FOCUS: SOLAR POWER
New Materials, Efficiency Upgrades Advancing Solar Technologies
Advancements in solar power technology are coming rapidly as growth in the
sector resumes after a pandemic-related slowdown. Partnerships and collaborations
are supporting research and development of new materials for higher
efficiency panels, better racking methods, and upgraded equipment designs.
FEATURES:
HYBRID POWER
Why Thermal Energy Storage Offers Hot Prospects for Power
Thermal energy storage (TES)-the temporary storage of energy by heating
or cooling a storage medium-is gaining interest and traction as a crucial
enabler of reliable, secure, and flexible energy systems. While molten storage
systems dominate TES applications in the power sector today, technologies
under development could facilitate demand shifting, variable supply integration,
sector integration, network management, and seasonal storage.
POWER EVENTS
Power Event Attendees Welcome the In-Person Experience
POWER brought energy industry executives, engineers, workers, and others
together in San Antonio, Texas, in October for its Experience POWER, Distributed
Energy Conference, and inaugural HydrogeNext events. For many, it was
their first in-person gathering in nearly two years, and attendees relished the
opportunity to meet and network with power generation industry colleagues.
CYBERSECURITY
How to Manage Cyber Risk as Grid Modernization Efforts Intensify
Cybersecurity in the power generation sector is only growing in importance,
with more bad actors and cyber criminals expected to prey on utilities and
the transforming transmission and distribution network. Companies need the
best tools at their disposal in order to manage those risks.

ON THE COVER
The cover includes a typical photovoltaic
module, and a graphic depicting the type
of solar cell that has traditionally been manufactured-the
p-PERC solar cell (shown
in the bubble on the left). Solar cells tend
to degrade over time. One hypothesis for
light-induced degradation of the silicon (Si)
bulk material is shown in the right-hand
bubble. These structures feature a substitutional
boron (B) atom and an oxygen (O)
dimer for the defect structure. The hydrogen
(H) atom represents the regeneration
process, where the H interacts with the
defect to completely passivate the structure.
