Reducing PV module temperature with cooled air from the ground
Researchers from Iraq have used computational fluid dynamics to simulate the operation of a 100 W panel with ground cooling. The proposed technique was reportedly able to reduce panel temperature by up to 28%, with power generation increasing by up to 6.5%.
Reducing photovoltaic-thermal module temperature with iron, copper oxide
An international research team has proposed using iron oxide and copper oxide to lower photovoltaic-thermal (PVT) solar module temperature. Their analysis showed that the two compounds were able to lower the panels’ operating temperature by 23.49% and 34.58% respectively.
New CIGS solar cell design with antimony trisulfide promises 31.15% efficiency
The novel solar cell uses antimony trisulfide (Sb2S3) as the back surface field (BSF) layer. According to its creators, this layer can be included in conventional CIGS solar cells to improve their efficiency and reduce the absorber material’s cost.
Reducing PV module temperature with beeswax, paraffin wax
Scientists in Iraq have applied two different kinds of phase-change materials to lower the operating temperatures of PV panels. Their experiment showed that beeswax and paraffin wax are particularly effective in achieving this goal, even when they are combined together.
