Experts seek policy for solar manufacturing base
Listen to article Experts at a high-level consultative session stressed that Pakistan must urgently develop a comprehensive policy framework to strengthen its domestic solar manufacturing ecosystem amid rising energy demands and growing reliance on imports. The session was hosted by the US-Pakistan Centre for Advanced Studies in Energy (USPCAS-E) at NUST. The event marked the launch of a study titled "Crafting a Sustainable Business Model to Drive Indigenous Solar PV Panels Manufacturing in Pakistan," presented by Dr Nadia Shahzad, Associate Professor at NUST. The study provides a roadmap for establishing a 100MW solar PV panel manufacturing plant in Pakistan, with scalability up to 1.0GW. Developed through site visits and stakeholder consultations, the model is seen as a practical starting point for local production. Welcoming the participants, Dr Adeel Waqas, Dean and Principal at USPCAS-E, underscored the need for a self-reliant solar manufacturing sector to meet the country's energy needs and reduce import dependency. The session brought together policymakers, academics, and industry leaders, all echoing the urgency to build a strong domestic solar base. Maud Osman Mohammad of LONGi Solar praised the study's clarity and urged aligning policy with market realities. Similarly, Muhammad Basit Ghauri from Renewables First noted that battery imports exceeding Rs90 billion in just three months reflect the market's potential. He emphasised the need for data-driven planning and integration of storage solutions behind the grid. Dr Omais Abdur Rehman supported a role for the Engineering Development Board, while Dr Noor ul Huda Khan of BUITEMS advocated for alignment with next-gen solar technologies such as Perovskite modules. On the technological front, Sohaib Asif Sipra, CEO of SkyElectric, warned that nearly half of Pakistan's solar installations remain informal, risking quality and safety standards. He called for the formation of a dedicated think tank to drive standardisation and innovation in battery and inverter manufacturing. Representing local battery production, Mansoor Jamil Khan of Atlas Battery highlighted their joint venture with Japan's GS Yuasa and advocated for lithium-ion safety protocols alongside continued dominance of lead-acid batteries. Policy-level recommendations were reinforced by M Umer Khan of the Private Power and Infrastructure Board (PPIB), who proposed targeted subsidies and strategic import duties to promote indigenous manufacturing. Hasnat Khan of the Pakistan Solar Association detailed their training and certification drive in partnership with institutions like TEVTA, NUTECH, and PPIB to ensure quality assurance in solar installations. Concluding the event, Dr Majid Ali, Associate Professor at NUST, reaffirmed the university's commitment to advancing indigenous solar manufacturing and called for ongoing collaboration among academia, industry, and government. The session served as a powerful reminder of the need for cohesive action and strategic investment to transform Pakistan into a hub of solar innovation and manufacturing.

As we delve into the intricacies of this innovation, it's clear that these flexible solar cells hold the promise of a brighter, more sustainable future. The Role and Importance of Perovskite in Solar Cells Perovskite, a crystalline material, has revolutionized the solar cell industry due to its outstanding optical properties. It is known for its remarkable ability to absorb light efficiently and its cost-effective production process. This material is particularly adept at converting a broad spectrum of wavelengths into electricity, making it an ideal candidate for solar cell applications. Moreover, its structure can be tailored to enhance performance. Unlike traditional silicon-based solar cells, perovskite can be deposited in thin layers, paving the way for flexible and lightweight applications. However, its long-term stability has been a persistent challenge. Recent studies, like the one conducted by Professor Jichun Ye's team, demonstrate that combining perovskite with other materials such as CIGS can significantly improve its durability, paving the way for more robust solar solutions. World's Largest Solar Telescope Unleashes 5.6-Ton Tech Beast to Capture Unprecedented Images of Massive Sunspot Activity Understanding the Functionality of a Tandem Solar Cell A tandem solar cell integrates two different semiconductor materials to capture solar energy more effectively. Each material is finely tuned to absorb a specific segment of the solar spectrum. In the case of perovskite and CIGS cells, perovskite is primarily responsible for capturing visible light, while CIGS excels in the infrared range. This complementarity greatly enhances the overall conversion efficiency. The construction of a single cell from these two materials presents technical challenges, particularly regarding the adhesion between layers. Innovative techniques such as the antisolvant-seeding approach are crucial in overcoming these issues. Tandem cells are the future of solar panels, with efficiencies that could potentially surpass current technologies. Their development is pivotal for advancing the energy transition.
