Modules & Upstream Manufacturing

U.S. scientists have demonstrated a perovskite-silicon tandem cell they claim has low reflectance losses and strong potential for commercial production. The tandem architecture involves a manufacturing process featuring the solution-based blading of perovskites onto textured silicon wafers.

Taiwanese manufacturer Heliartec Solutions is offering BIPV panels for building facades that can be designed to mimic different kinds of textures in conventional building materials. The panels can also work as colored laminated safety glass and replace traditional cladding in the ventilated facades of buildings. They vary in length from 60 cm to 240 cm, with widths ranging from 30 cm to 120 cm. Depending on their size, the panels can offer power outputs of 90 W to 150 W per square meter.  

The patent infringement claim concerns a process for separating photovoltaic strips from silicon solar cells for use in more-efficient tiled or “shingled” solar panels.

A new paper published by researchers at Malaysia’s Multimedia University provides a new method to assess the effectiveness of different cooling systems for photovoltaic modules. The proposed technique relies on measuring the output of the module with added cooling and comparing this to its power rating under standard test conditions.

The losers in a world which no longer runs on fossil fuels are obvious but the dividend from shrugging off hydrocarbon dependency will be spread around most of the world so it is the nations which are winning the cleantech manufacturing and intellectual property race which appear best positioned for the future.

The Fraunhofer Institute for Solar Energy Systems’ (ISE) CalLab has confirmed the new efficiency rating. The researchers have combined semiconductors, perovskites and CIGS to produce a monolithic two-terminal tandem cell.

Although the energy price recovered this week, ultra low levels driven by bumper solar power generation on a sunny weekend in Germany reportedly put further pressure on the business case for conventional energy.

A failed top rail girder connection was responsible for the 2019 roof collapse at AZ Alkmaar’s football stadium, an investigation by Dutch engineering firm Royal HaskoningDHV has revealed. The collapse was triggered by strong wind loads during a storm.

The new regulations state that import duties on solar modules will now be calculated per kilogram rather than by square meter, as they were under the old regulations. This could favor Turkish manufacturers, as high-efficiency modules are generally now heavier than they were a few years ago. Under the previous rules, PV panel imports enjoyed reduced value-added tax rates as yields increased and module sizes remained unchanged.

The lure of building integrated photovoltaics continues to attract entrepreneurs and startups.
