What are the power conversion efficiencies of a single-junction OSC?
To date, the power conversion efficiencies (PCEs) of the rigid and flexible single-junction OSCs exceed 20 and 18%, respectively (4 – 9). The strides made in high-efficiency OSCs were predicated on the development of organic semiconductors and device structures that improve the efficiency of sunlight utilization.
What's new in a one-sun solar module?
There are five new results reported in Table 4 (one-sun modules) involving a range of technologies. The first is a new efficiency level of 24.9% reported for a 1.8-m 2 silicon module 60 fabricated by Maxeon Solar Technologies and measured by NREL. Maxeon is one of the leading proponents of the interdigitated-back-contact (IBC) cell.
Are bifacial silicon solar cells good for solar energy conversion?
Now, commercialized bifacial silicon solar cells have shown great superiority in solar energy conversion. Notably, the thickness of the silicon layer is approximately 200 μm, which allows for strong light harvesting under both front and back illumination (37 – 39).
Can solar cells be contacted with a busbar?

What is the difference between bifacial and monofacial solar cells?
The decisive difference between bifacial and monofacial solar cells is the rear transparent electrode (TE) that permits the propagation of albedo light into the active layer. However, it is well known that OSCs using rear TE are always transparent, implying severe optical loss and poor efficiency (left part of Fig. 1B) (40).
