Indian PV manufacturers are looking beyond tunnel oxide passivated contact (TOPCon) solar. Back-contact (BC) devices are an enticing prospect but many feel the technology is not mature enough. Uma Gupta considers the cost, yield, and reliability challenges that BC solar has to overcome.

The latest supply chain map from Sinovoltaics tracks growth across Southeast Asia, with module capacity reaching 78.8 GW, and 58 production projects tracked.

India’s cumulative solar module manufacturing capacity reached 77.2 GW, and solar cell manufacturing capacity totaled 7.6 GW as of June 2024, according to Mercom India.

Livguard has launched its high-frequency solar inverters that are compact, lightweight, and low-noise.  

ESG (environmental, social, and governance) measurement is often inconsistent, as there are multiple ESG rating agencies, sustainability reporting standards and data providers and all deploy their own methodologies and parameters. That makes it challenging for the investors and other stakeholders to evaluate critical ESG metrics and make well-informed choices.

Honeywell is integrating ultrasound scanning-based comprehensive battery cell testing in its Battery Manufacturing Excellence Platform (MXP) software solution, enabling high-quality battery production by giga-factories. Also, it is launching new safety sensors that detect thermal runaway signs in EV batteries before a potential fire.

Considering India’s energy demand doubled between 2000 and 2020 and is set for a tremendous surge to the tune of 73 exajoules (EJ) by 2050, we really have to focus on achieving sustainable energy security for decades to come. This systemic transformation won’t come merely with government directives or policy measures but would warrant a mindset change towards sustainability.

A group of researchers has proposed a new method for the sizing of PV systems that do not rely on an anti-dump system and operate without the possibility of injecting power into the grid. The novel approach requires an estimate of the annual hourly profile and the minimum power demanded, as well as the use of an irradiance meter and an electrical network analyzer.

Researchers at the University of New South Wales claim to have identified new TOPCon contact degradation mechanisms that are significantly influenced by the combination of ions and aluminum-silver paste compositions. The primary degradation mechanism was a significant increase in series resistance.

Avaada will set up a wafer-to-module project to support the company’s existing PV module plant in Dadri. The factory will also manufacture next-generation batteries and electrolyzers.
