BIPV

Scientists in the Netherlands have developed a model to forecast the energy yield of a PV system. It is able to take into account factors such as partial shading and multiple module orientations. Tested against a reference cell and pyranometer, the model showed less than 5% error, and the scientists claim their approach is up to three orders of magnitude faster than more common approaches using complex ray tracing.

Estonian startup Solarstone has developed two solar tiles with an efficiency of up to 19.5% and an operating temperature coefficient of -0.41% per C. It recently secured €10 million in funds to expand sales across Europe.

Swansea University will collaborate with Indian multinational Tata Steel to investigate perovskite solar cell materials that could be applied directly onto coated steel to make building-integrated PV components. The partnership will add to an “active buildings” project that the Welsh university has been running for several years.

A research team in Hong Kong has built a solar window that can generate power on the external side via a luminescent solar concentrator and thermal energy on the internal side via transparent solar absorbers.

Taiwanese manufacturer Eterbright has developed a CIGS solar tile with power output ranging from 26.5 W to 56 W and a temperature coefficient of -0.34% per C. The product is able to withstand a snow load of 5,400 Pa and a wind load ranging from 1,600 Pa to 2,400 Pa.

A consortium led by building-integrated photovoltaics maker Mitrex wants to install highway noise barriers with integrated solar that have 1.2 MW of capacity per kilometer. The technology is currently in the pilot phase at government entity locations in North America.

With architects and construction companies across the world showing an increasing interest in building-integrated PV, one Australian company has outlined plans to clad an eight-storey building being constructed in West Melbourne with a “solar skin” that will generate almost all of the building’s base power.

German scientists have reviewed all solar cell technologies with tuning capabilities and have identified all of their possible applications.

Scientists in Italy have developed a module with an area of 0.2 sm and an efficiency of 2.7% in outdoor conditions, with a tilt angle of 60 C. They designed it by considering the trade-off between low losses and device sturdiness.

The new solar module can be purchased with different levels of transparency, depending on the project, with light transmittance ranging between 30% and 40%. It has a power output of 245 W to 300 W and a temperature coefficient of -0.30% per C.
