Solar energy: India's renewable energy boom faces a hidden waste problem

A recent study has found that India will generate over 11 million tonnes of solar waste by 2047 if it does not scale up recycling.

Terawatt Solar Photovoltaics (2014):

"We can treat the dead wafer-Si cells as impure metallurgical-grade Si and go through the rest of the process flow... There are few cost or energy benefits in such a process flow as compared to the process flow with quartz as the starting material, as dead wafer-Si cells would have to go through all the energy-intensive steps"

Solar energy will undoubtedly become a main source of energy in our life by the end of this century, but how big of a role will photovoltaics play in this new energy infrastructure? Besides cost and efficiency, there are other barriers for current solar cell technologies to become a noticeable source of energy in the future. Availability of raw materials, energy input, storage of solar electricity, and recycling of dead modules can all prevent or hinder a tangible impact by solar photovoltaics. This book is intended for readers with minimal technical background and aims to explore not only the fundamentals but also major issues in large-scale deployment of solar photovoltaics. Thought-provoking ideas to overcoming some of the barriers are discussed.

Cell Reports (2025):

"Given the high amount of energy consumed in manufacturing Si wafers and cells, solar panel design may require an overhaul to allow the full recovery of Si cells... This is important for products with more than one type of intensive input (e.g., material and energy for PV modules)."

Newer PV is thinner, cracking easier, shortening lifespans, causing concern that multiple PV product generations will expire at the same time.

"Due to silicon cell cracking, Photovoltaic (PV) module reliability issues are gaining great attention due to the increasing demand for solar power and the reduction of cell thickness to reduce cost."

Earlier generations of Si-PV last longer, for example the original Si-PV cell (1 cm thick), 70 years old, is still operational.

"The thickness of the solar cells has been decreased... These changes have rendered the cells more brittle and susceptible to fracture while handling, storage and lamination of the module."
