A United States-based collaboration between the National Renewable Energy Laboratory and CubicPV has yielded a perovskite minimodule with certified efficiency of 24.0%. The two noted that it is the first time a U.S. effort has set a record in the perovskite mini module category.

In a novel combination of micro-concentrators and picosecond laser processing, Italian researchers are tackling two metal halide perovskite solar PV challenges to reduce the use of lead and extend stability of the power conversion efficiency.

PV module manufacturing capacity in Southeast Asia has reached 86.5 GW across 61 active sites, according to Hong Kong-based quality assurance firm Sinovoltaics. The figures come from the company’s latest “Southeast Asia Solar Supply Chain Map” report.

Researchers from Swiss and Austrian institutions have demonstrated a novel design for a glass-free, structurally robust silicon PV module. With a weight below 6 kg/m2, the targeted application is older buildings with weak roof structure.

An international team of researchers used a novel interfacial treatment to improve the performance of perovskite solar cells across a range of narrow and wide bandgap single junction, tandem, and mini-module samples. An all-perovskite tandem solar cell demonstrated its use with a certified efficiency of 29.5%.

Researchers in Netherlands and Belgium have created a numerical model to simulate the moisture ingress in PV modules. Their research work showed that climate in which a PV module is installed has a much higher impact on the moisture ingress than the choice of materials for the encapsulant of the backsheet.

An international research team studied the solar PV impact of emissions from a coal-fired power plant in the Atacama Desert, Chile finding that after five months of exposure, the deposited dust on co-located PV panels reached a maximum of 1.63 mg/cm2 with a 23 % reduction in photocurrent. The accumulation at the co-located plant was 3 times greater than nearby PV sites with similar coastal climate conditions.

Researchers at Thailand’s Vidyasirimedhi Institute of Science and Technology demonstrated a novel hydrogel that has high cooling effect on silicon PV panels.

To make it easier to adopt building integrated PV as a glazing material, a group within the IEA Photovoltaic Power Systems Program (IEA-PVPS) has tackled the solar heat gain coefficient calculation for BIPV. It is part of IEA PVPS Task 15 international standardisation efforts.

UNSW researchers were able to recover silicon from end-of-life solar PV panels pure enough for re-use in silicon carbide-based devices. Their novel multi-step method, that includes thermal and chemical processes, also recovers silver.
