There are misconceptions about how much solar panels costs and how will the return on investment be. The cost of solar panels has been a tale of falling prices. In 2000, the global average price of solar PV modules was 4.99 US$ per watt. In 2019 the global average price has fallen to 0.38 US$ per watt. Lower costs mean a shorter payback period.
Sustainability is the need of the hour to tackle our growing energy needs. To make progress in reducing greenhouse gas emissions energy is one of the fundamental areas we need to work on. By shifting towards renewable sources, nuclear and relying less on natural resources we can decarbonize the energy systems. It is important to harness them correctly and make maximum use of the capacity.
Oxford PV a perovskite developer has set out a new world record for perovskite-silicon tandem cell efficiency at 29.52%, edging out the previous record set less than a year ago by Helmholtz Zentrum Berlin. This new record places these tandem cells as the future of PV.
