This article is very misleading. Solar is measured in power/area, not power/weight. Telling us the power/weight ratio merely tells us that these cells can be produced cheaply. 18 times more power per kg, but weighing 100 times less, means that if I have 2 solar panels with the same surface area, the one made from the new material will produce 0.18 …

A solar module comprises six components, but arguably the most important one is the photovoltaic cell, which generates electricity.The conversion of sunlight, made up of particles called photons, into electrical energy by a solar cell is called the "photovoltaic effect" - hence why we refer to solar cells as "photovoltaic", or PV for short.

A photovoltaic cell is an electronic component that converts solar energy into electrical energy. This conversion is called the photovoltaic effect, which was discovered in 1839 by French physicist Edmond Becquerel1. It was not until the 1960s that photovoltaic cells found their first practical application in satellite technology. Solar panels, which are made up of PV …
Although Yang et al.
