PV modules

The result is claimed to be the highest efficiency ever reached for a large-area, polymer film-based perovskite photovoltaic module. The device has an area of 703 square centimeters and was fabricated through a new coating method.

Scientists in the United States explored the use of all back contact architectures for perovskite solar cells. The group notes several advantages to this strategy, as well as challenges to overcome. Ultimately, the work outlines a route to cell efficiencies better than 20%.

The Latin American country may see unprecedented growth for PV systems not exceeding 5 MW in size during this decade, according to Brazil’s state-run Empresa de Pesquisa Energetica (EPE) agency. New rules now under discussion in the parliament may further boost this market segment and lead, eventually, to another 30 GW of installed solar power.

The three Chinese panel manufacturers found an agreement on the module size and the mounting hole spacing.

Brazilian researchers have proposed a new mathematical model to change parameters for wind and solar resources and different levels of energy demand. The model was originally conceived for tropical regions, but it can actually be used in any location. The new methodology models a highly complex system featuring wind turbines and PV modules, as well as solar collectors, fuel lines, gas boilers, engine-generator sets, recovery boilers, absorption and compression chillers, and grid electricity.

Maxwatt Solar has built a PV system that is purportedly India’s largest residential on-grid residential solar installation, with 540 Wp modules. It uses 68 of JA Solar 540 Wp half-cell mono PERC modules and a 27 kW Fronius inverter.

Scientists in China found that a change to the hole transport layer material helped to reduce voltage loss in a perovskite solar cell. The discovery demonstrates a promising new pathway to overcoming a major challenge for perovskites – particularly those used as the top layer in a tandem device.

A booming overseas market has offset falls in demand in China caused by rising solar module prices, according to Flat Glass. In common with its PV glassmaking rivals, the company is pressing ahead with production expansion, betting reduced prices for its products will feed even greater demand.

The frameless design of the 50 kW facade was made possible by a concealed suspension technology that, according to its creators, eliminates the need for additional edging at the edge of the module. The installation was built with 135 W CIGS solar modules.

The mounting structure relies on a 5.8m long support rail that does not lie on the roof but is connected directly to a purlin placed below with self-drilling support screws.
