Multi-junction (tandem) solar cells (TSCs) consisting of multiple light absorbers with considerably different band gaps show great potential in breaking the Shockley–Queisser (S–Q) efficiency limit of a single junction solar cell by absorbing light in a broader range of wavelengths. Perovskite solar cells (PSCs) are ideal candidates for TSCs due to their tunable …
Conclusions We have demonstrated, for the first time, a maskless and contactless method to fabricate IBC-HJT solar cells. The novel element is an etching step that uses a patterned RF powered electrode in a capacitively-coupled PECVD chamber rather than a mask to create the P and N regions.
Solar cells were fabricated using an identical process to the one that generated the I–V characteristics shown in Fig. 10, but including the additional “gentle” etching step, which completely removed the (i)a-Si:H within the trench.
Notably, the Anti-Burstein-Moss effect of TTO is observed, which is ascribed to variations of stress in films. Based on this finding, TTO was first applied to SHJ solar cells, and the photoelectric tradeoff in front and rear contacts is gained by matching nanocrystalline silicon layers and adjusting TTO thickness.
Although the fundamental physics and chemistry of a particular solar cell do not change while scaling up the size of a cell, maintaining the electronic quality over large areas and achieving the high manufacturing yields necessary to be able to build modules are challenging and require the ability to reproducibly fabricate large-area cells.
In the field of thin film solar cells, pinholes are a common problem. As shown in Fig. 21, there are pinholes in the absorber layer, the metal in the back contact can fill the pinholes, so it will directly contact with the p-n junction and create a direct or a weak shunting of the p-n junction.
After this patterned etching process, a necessary step for good solar cell behavior is the removal of the top-most surface layer, which appears to be damaged by the patterned etching process, through a “gentle” blanket etching process.
