First attempt to build ‘shingled’ perovskite-silicon tandem solar cells
Fraunhofer ISE researchers have demonstrated for the first time the feasibility of the shingling approach with perovskite-silicon tandem solar cells. They also produced full format photovoltaic modules with a power conversion effciency of 22.8%.
Novel solar module encapsulant based on glass-fiber, epoxy resin
Researchers in Spain have used a glass fiber reinforced composite material with an epoxy matrix containing cleavable ether groups as an encapsulant material for photovoltaic panels. They found that new material still has issues with performance stability, but they also ascertained it ensures lower electrical losses.
Hybrid photovoltaic-tidal energy system for island resorts
Scientists in India have proposed to combine solar PV with tidal energy and storage to cover the entire electricity demand of island resorts. They found the system could help to reduce energy costs for residents and businesses.
Japanese scientists design flexible crystalline silicon solar modules with PET front cover
The new solar panels have flexible properties and are suitable for roofs with loading restrictions. According to their creators, the modules showed high reliability under both high temperature and high humidity conditions.
