Thin Film Solar Cell (1) – is by Eren Ore, a second-year PhD student in the electronics, power and energy conversion group. The image is of a solar cell, the kind used to harvest the Sun's energy. However, solar-cell technology is very costly to produce. Ms Ore is trying to develop very thin cells to produce efficient solar cells that cost less. In this photograph, a multi-layered thin film solar cell has developed various bubbles and crinkles – resulting in this beautiful, microscopic picture.
