# ∂PV
A photovoltaic simulator with automatic differentation, built on `JAX`.
Pull requests welcome!
Currently targeting inorganic materials.
For more examples, including performing efficiency optimization of a perovskite solar cell and discovering unknown material properties in a cell, see the following [Google Colab](https://colab.research.google.com/drive/1d2vY01LhXUKOHasNOOZj17FO7qGgWBph?usp=sharing)
To install via `pip`, simply use the command
```
pip install deltapv
```
`deltapv` features a simple interface for most common cell structures. For a simple p-n homojunction, the following code computes the IV curve:
```python
import deltapv as dpv
material = dpv.create_material(Chi=3.9,
Eg=1.5,
eps=9.4,
Nc=8e17,
Nv=1.8e19,
mn=100,
mp=100,
tn=1e-8,
tp=1e-8,
A=2e4)
des = dpv.make_design(n_points=500,
Ls=[1e-4, 1e-4],
mats=material,
Ns=[1e17, -1e17],
Snl=1e7,
Snr=0,
Spl=0,
Spr=1e7)
results = dpv.simulate(des)
```
Several convenient plotting functions are provided to visualize important quantities.
```python
dpv.plot_iv_curve(*results["iv"])
dpv.plot_bars(des)
dpv.plot_band_diagram(des, results["eq"], eq=True)
dpv.plot_charge(des, results["eq"])
```
