Bifacial Solar Cells
Our ‘Solar Shutters’ ‘Superbright Solar Panels’ and ‘Superbright Solar Wall Cladding’ utilise Bifacial solar cells that are designed to allow light to enter from both sides. They typically employ a front surface design similar to that used in industry standard screen-printed solar cells with the major point of difference being the structure of the rear surface contact. Rather than cover the entire back surface with a reflective aluminium contact, a ‘finger’ grid is used in its place in order to allow sunlight through the rear.

Typically, the silicon material used for bifacial solar cells must be of superior quality such that photo-generated electric charges near the rear surface can contribute to power production as they travel towards the ‘emitter’ on the front surface. This design also necessitates the use of transparent encapsulating materials on both sides of modules.

Historically bifacial solar cells were targeted towards ‘Building Integrated Photovoltaic Applications’ or in areas where much of the available solar energy is diffused sunlight which has bounced off the ground and surrounding objects i.e. extreme latitudes and snow‑prone regions. However, the combination of plateauing peak efficiencies from standard screen printed solar cells has pushed bifacial solar modules back into the spotlight.

Vertically integrated
In order to better match onsite demand with PV generation profiles throughout the day a vertical panel orientation where both the front and rear sides of the panels are exposed to peak morning and afternoon direct and diffused sunlight creates a ‘double-peak’ profile that can better match on-site electricity use, especially for residential and commercial installations.

This unconventional approach of vertically installed bifacial modules would more than halve the number of modules needed for an equivalent installation. This configuration would again produce two generation peaks but would also benefit from the additional diffuse light entering the module from the indirect side.

Cost comparisons
In comparing the financial merits of single-sided against bifacial modules, the effective levelised cost of electricity (LCOE) over the project lifetime should be used as the deciding metric and not just the dollars‑per‑peak‑watt cost of respective modules. For grid-connected PV consumers, the ability to more closely match PV generation profiles with onsite demand throughout the day – thus maximising the use of generated PV electricity rather than feeding it back into Australian grids at reduced rates can boost returns on a PV investment, despite a marginally higher upfront cost with bifacial technology.
