AI Customer ServiceA homojunction solar cell based on single crystalline silicon with an efficiency of 6% was firstly reported in 1953 . There was little progress in this area until 1970s when a dramatic increase in the efficiency of up to 16–20% was observed for Si p-n homojunction solar cells .
The homojunction tandem organic solar cell is a prototypical organic tandem structure designed to boost the efficiency of a single device by improving absorption and charge extraction .
A thin film based homojunction solar cells requires the proper choices of active materials, contact electrode materials as well as synthesis techniques. Moreover, their efficiencies can be further boosted by adjusting various doping levels for p and n-type semiconducting materials.
We review the development of homojunction solar cells with two-dimensional (or thin film) based materials, one-dimensional materials (nanowire/nanorods/nanotube), and zero-dimensional (nanodots and quantum dots) based materials.
Recently significant development has been achieved in the p-n homojunction QD solar cells, with improved V oc and stability in these solar cells, which were mainly attributed to the solid-state ligand exchange and ligand effect due to the properties of QDs .
Whereas the homojunction solar cells are based on layers of same or similar semiconductor materials with different doping levels , and p- and n-types are created in the same or similar materials thus generally producing a good lattice matching.
