That’s the reason for the vast versions of SPICE available now decades after the original was released, not all of which are as open or free as we might like. Qucs is a GPL circuit simulator.

The researchers built the cell with a hole transport layer (HTL) based on PEDOT:PSS and were reportedly able to reduce the ...

Researchers from Canada have developed solar cells that boast a record-breaking open circuit voltage. The solar cell design features indium gallium phosphide (InGaP), indium gallium arsenide ...

Luckily, there’s a fully featured free and open source circuit simulation software called Qucs (Quite Universal Circuit Simulator), released under the GPL, that offers a decent alternative to ...

Researchers at Tohoku University in Japan claim to have developed a tin(II) sulfide (SnS) solar cell with a high open-circuit voltage, due to an SnS interface exhibiting large band bending.
