Closed-loop recycling of photovoltaic panel materials could mitigate up to 0.2% of Flanders’ annual environmental impact

The development of future recycling technologies must be informed by data about products and materials that will enter the waste stream, but such forecasts are subject to a high level of uncertainty. In this study, researchers have proposed a methodology for predicting emerging waste materials, applying it to silicon-based photovoltaic (PV) panels. The findings show that closed-loop recycling — when post-consumer waste is recycled to make new products — of PV panel materials could mitigate up to 0.2% of the annual environmental impact of Flanders1, Belgium, if suitable technology was developed.

Modern photovoltaic systems provide competitive energy returns

Most modern societies depend on fossil fuels (oil, gas and coal) as sources of energy for development and growth. Switching to renewable energy sources, such as photovoltaic (PV) systems, is necessary for sustainable development in the future. A new study suggests that it is currently much more efficient to use fossil fuels to develop PV power plants than to combust the same amount of fossil fuels in conventional thermal power plants: thus the sooner PV systems are developed, the sooner society will reduce its reliance on fossil fuels.

Photovoltaic supply falls short of solar power targets

Europe could struggle to meet the target set by the renewable energy sector of 25% of electricity produced by solar energy by 2040 because the supply of materials, including rare metals, needed to produce photovoltaics (PV) is unlikely to meet demand. Production rates need to be drastically improved, according to a new study.

Forming graded index lens in an all atmospheric pressure printing process to form photovoltaic panels

A PV panel uses an array of small silicon sphere diodes (10-300 microns in diameter) connected in parallel. The spheres are embedded in an uncured aluminum-containing layer, and the aluminum-containing layer is heated to anneal the aluminum-containing layer as well as p-dope the bottom surface of the spheres. A phosphorus-containing layer is deposited over the spheres to dope the top surface n-type, forming a pn junction. The phosphorus layer is then removed. A conductor is deposited to contact the top surface. Alternatively, the spheres are deposited with a p-type core and an n-type outer shell. After deposition, the top surface is etched to expose the core. A first conductor layer contacts the bottom surface, and a second conductor layer contacts the exposed core. A liquid lens material is deposited over the rounded top surface of the spheres and cured to provide conformal lenses designed to increase the PV panel efficiency.
