Perovskite-cadmium telluride tandem solar cell based on special electrode achieves 24.2% efficiency

An Indian-US research team has fabricated a four-terminal perovskite-cadmium telluride tandem solar cell by utilizing a highly conductive and sputtered transparent electrode to increase the current density of the bottom cell. The tandem device combines a 18.3%-efficient top perovskite cell and a 19.53%-efficient cadmium telluride bottom device.

Assessing feasibility of solar arrays at airports

A team of researchers developed a methodological framework for assessing solar potential at airports and applied it to seven Indian airports. They found the greatest potential at an airport in Raipur, central India, where they say an at least 21 MW array could be installed without compromising customer experience or safety.

UIS installs recoating solution at 2 GW solar wafer factory in India

UIS Technologies has commissioned polyurethane (PU) recoating and regrooving solutions for wire guide rollers (WGRs) at Adani’s 2 GW solar ingot-wafer plant in Gujarat, India.

PV string fault detection technique based on multi-layer neural network

Scientists in India have proposed using a multilayer neural network to find line-to-ground, line-to-line, and bypass diode faults in PV module strings. They tested the new approach on a 22.5 kW solar array and reportedly achieved “competitive” accuracy results.
