'Although the development of bifacial solar cells dates back to the 1970s, due to the expensive cell structure, bifacial modules have remained a niche product in the market.

'In contrast to single sided cells, bifacial cells collect radiation on the front and rear side as they capture light reflected from the surface beneath the module and from the surroundings. On flat roofs, ground-mounted installations or locations that might not initially seem the best for a solar panel, however, bifaciality can improve energy generation by up to 25% more than standard panels.

'The advent of new and economically viable glass provides the ideal technology for generating higher energy yields. However, before this technology sees large-scale market distribution, several hurdles have to be overcome. Unlike single-sided panels, we need to examine the 'albedo' (light reflectivity) of the surface underneath the panel that can affect performance and then make accurate energy yield assessments by adapting and using state-of-the-art modelling tools. We will also perform a detailed investigation into high albedo surfaces in relation to radiation augmentation of bifacial modules, ageing, degradation, costs and environmental impact.'
